# How to Convert Water into Fuel by Building a DIY Oxyhydrogen Generator

Here's how to build a sexy looking generator that uses electricity to convert water into an extremely powerful fuel!  In this project, you'll learn how to build an OxyHydrogen generator from scratch.

## Step 1: What Is an OxyHydrogen Generator?

An oxyhydrogen generator, like this one, uses electricity from your car battery to split water into hydrogen and oxygen gasses.  (Electricity + 2H20 --> 2H2 + O2)  Together, these make a fuel that is much more powerful than gasoline, and the only emission released is—water!

Of course, to be a completely clean fuel, the electricity used to generate the gas needs to be from a clean source.  Solar, wind, or water power could be a few examples.

This video shows step-by-step how to make one.

NOTE: The amount of electrical energy required to make the gas is more than the energy you can obtain from it.  This is NOT an energy generator so much as it is an energy converter.

## Step 2: Getting Metal For The Generator Plates

For this project, you're going to need some stainless steel and some ABS pipe fittings. I visited a local fabrication company, and not only did they have plenty of scrap metal to choose from, they were even willing to help me cut it to custom sizes. A job that would have taken me hours with a pair of tin snips and a hacksaw took only a matter of minutes with their equipment.

I used 20 gauge stainless steel, and with the help of their hydraulic punch, cut precise holes in the tops and bottoms of the plates. When finished, I had 12 plates measuring 3" x 6", 4 plates at 1-1/2" x 6", and three 1" connector bands that were 6", 4-1/2", and 3 1/4". A belt sander was used for smoothing down the jagged edges around the hole.

## Step 3: Increasing The Plates Surface Area

Next I used 100 grit sandpaper to sand each of the plates diagonally. You can see the "X" pattern I sanded into both sides of the plates. This increases the surface area of the plate, and will assist in producing more gas.

## Step 4: Configuring The Plate Assembly

The plates are joined in a configuration so that the 2 inner plates are connected to one electrical terminal, and the 2 outer plates connected to the other terminal.  Plastic rods, plastic washers, and stainless steel nuts help to form the proper electrical connections.

The generator plates are assembled in the order of plate, plastic washers, plate, stainless steel jam nuts until 8 plates have been connected.

To see a step-by-step of the generator plate assembly, watch that specific portion of the video here.

When the plates are assembled, a 4" ABS clean out plug is attached at the top with some stainless steel bolts.

## Step 5: Making The Generator Body

The body is made from two 4" ABS clean out adapters, with a 4" plug inverted and cemented into the bottom. A 4" tube of acrylic or ABS makes the body, and the generator plates and cap screw down into the top.

A water bubbler is made in a similar fashion out of 2" clear acrylic tubing, but needs a way to clip onto the side.

## Step 6: Making Clips For The Bubbler

Clips can be made from scrap acrylic or ABS tubing, and glued to the side of the body.

To make these clips, I cut 3/4" off the 2" tubing I used to make the bubbler, then cut the top 1/3" off to form a claw.  These were then cemented to acrylic rods, and attached to the side of the generator body.

## Step 7: Adding a Check Valve

Some poly tube, and a one-way check valve is added to the top elbow, making sure the valve will let gas out, but nothing back in.

## Step 8: Making The Electrolyte

The electrolyte is distilled water and about 2-4 teaspoons of KOH (potassium hydroxide). Salt or baking soda could also be used, but may dirty and corrode the plates over time.

I stirred the KOH flakes into the water, then used a coffee filter to strain the solution into the generator casing (after it had been cleaned thoroughly).

Note: Potassium Hydroxide is caustic and can burn the skin.  Avoid direct contact!

## Step 9: Finishing Touches

Water is added to the bubbler, then the cap is put back on, and the poly tubes are hooked up.

I tested it out with a 12 volt car battery and some jumper cables. The gas formed is collected it in a small water bottle, and ignited with a flame.

On 12 volts, this produces about 1.5 LPM.  I also hooked it to 2 car batteries in series, and on this higher 24 voltage, the system produced over 5 LPM and filled up a gallon milk jug in 38 seconds!

Note:  Higher voltages allow more current to flow through the system, and it heats up quickly over time.  If allowed to continue, there is a risk the plastic casing will melt from prolonged exposure to high temperatures.

## Step 10: How Powerful Is The Gas?

This system was not designed for use in a vehicle, but more as a device to demonstrate the electrolysis of water and what the gas can do.

To see some experiments where the gas was ignited, and some useful features of the generator, check out the video.

How large of a unit would I need to build to help an F-250 Powerstroke get better mileage?

would the effort result in more MPG?

And before the whiners start..

I DO NOT expect to make a diesel run on Hydrogen.

Just help on the economy.

Haha, don't even coun't the energie you lose from your batterie with all the waste to make hydrogen.

And that's before the injection/combustion process.

At this rate, you make more economie to try to put directly your batterie energie into the motion. Lol

Weish and Kurt explain it to you clearly and paulH11 give you a link for if you realy want to know.

But at better you say you are sure they are wrong (at worst, you know it, but hope faith in you misundesrtanding gona alternate reality).

So why would you that i explain to you in an bad english (not my birth language by the way) when you don't listen on 3 people who explain clearly ?

Personaly i know why, cause you think you know science, because you read a lot about N. Tesla on Conspiracy theorist /Illuminati /UFO sites.

And for proving what i said, first YOU argh and proove nothing, second i'm not an expert, but the little i know is from real science book (in your language often for remebder. So you can easly find them) and the most important :

If a man argument that if he run enough fast and light weigh he can fly, lot of people gona try to explain to him that jumping nude from a cliff is not a good idea and a realy bad understanding of science studies. But if you don't listen to them and call them "obstacle of new finding" for exemple, i don't gona loose my breath for him and just watch him realise too late that he better have REALY read science than just aving faith in HIS reality.

So yeah. Our comments reflects our intellectual capabilities !

A tips for the futur, if you don't want to sound like a conspiratie fan, read science mag and books where they don't speak about illuminati and UFO. It's easy to find in your language most of my science books are in your language.

Those people that are putting a hydrogen generator on their vehicle to create hydrogen that they mix with the gasoline or diesel to get better mileage are either shysters trying to sell a system or deluded users that don't understand physics and conservation of energy. It can not work.

And if you had a hydrogen generator in your backyard how are you going to get the hydrogen to your vehicle anyway. A gallon jar full of hydrogen gas is very little hydrogen and you have to pressurize the hydrogen to make it a liquid. Can you do this?

Then even if you did get a source of hydrogen to your vehicle the mix of gasoline and hydrogen has less energy that pure gasoline. Same with diesel. Hydrogen has less energy per pound that either gasoline or diesel.

Mixing hydrogen with gasoline to improve fuel mileage does not work. You can reply to me and argue all you want, you can say it did or does for you, you can say you tried it and it does work. You measured incorrectly. It does not work. Don't reply and challenge me as to what makes me an expert. Read and learn some physics. It's not my idea, it's physics.

Using electricity to make hydrogen in order to use the hydrogen as an energy source is a losing proposition. Just use the electricity instead.

Well to be true it is possible as i have just watched it on tv a company have created a car than can run on hydrogen and you put the water in the car using the same system you are obviously out of date with your information i believe the car company called scorpion
4 days ago

No, it is not possible. No I am not out of date. That system has been around for 40 years. It does not work. It is a scam. You believe everything you read on the internet. I have some swamp land I'd like to sell. It's pretty cheap and you can drain it with a \$10.00 drill pump.

4 days ago

You are absolutely correct, but don't waste your breath explaining actual science to people who believe anything they've seen on TV.

Law of conservation of energy clearly states that a system cannot generate as much energy as it consumes; hence, generating the electricity to split water into H2 and O will consume FAR MORE FUEL than is saved by feeding the hydrogen back into your engine.

I've watched a lot of magic shows that seem real as well, and scam artists are good at what they do.

This is a beautifully made project, but the ONLY current use for hydrogen as a fuel source is storing excess generated energy long term, which will leak from conventional batteries. Hydrogen is exceedingly abundant in our universe, but good luck getting it in its raw form without using some other form of energy. It's that extra energy consumption that makes it not worth the effort (at least given current technology).

4 days ago

mmmm Kurt?

Following your lead, it is "impossible" to generate enough energy by converting water to Hydrogen because it takes more energy to produce the Hydrogen than can be generated by the produced Hydrogen.

So, the car that starts on gasoline, then switches to produced Hydrogen will not produce enough Hydrogen to keep the engine running....

BUT the vehicle not only produces enough to produce the Hydrogen, but there is enough left over to power the vehicle at highway speeds.

3 days ago

Seriously, WTF are you talking about?

If you have created or found a perpetual motion machine, then you deserve a gold star. Do you have any idea how anything actually works?

We're not talking about Hydrogen Fuel cells - that is a totally different ballgame which has absolutely nothing to do with gasoline. A car does not "start on gasoline" then switch over to anything, except in the case of some hybrid-electric vehicles.

The engine runs from an internal combustion (a litteral explosion) from a mixture of gasoline and oxygen. Adding hydrogen to the mix CAN increase performance; however, you CANNOT produce the hydrogen from electricity generated by the car itself. That electricity is powered by the alternator (which charges the 12V battery and such) which is turned by the engine which RUNS ON GASOLINE. Not Hydrogen. To produce enough electricity for electrolysis, the engine has to work harder, hence it consumes more gasoline.

Note, I said "gasoline" here because people seem to be confused by the term "fuel." Diesel or ethanol could have been used as well.

3 days ago

You just stated that Hydrogen is not combustible enough to power an engine.

Would you be interested in rethinking that comment?

And nobody mentioned any "perpetual machines" so quit pretending to have any clue as to the actual subject of this thread.

Next you will say that cars can't run on Propane because they only run on gasoline.

2 days ago

Again, WTF are you talking about. I have never once said "Hydrogen is not combustible enough to power an engine."

Nope. Not even close. I did say this: "the ONLY current use for hydrogen as a fuel source is storing excess generated energy" as well as this: "Adding hydrogen to the mix CAN increase performance."

But nowhere did I say whatever nonsense that is that you think I said.

You actually said this: "BUT the vehicle not only produces enough to produce the Hydrogen, but there is enough left over to power the vehicle at highway speeds." Which is pretty much the definition of a perpetual motion machine. A system CANNOT produce more energy than it consumes. CANNOT.

Hydrogen is not a viable fuel source because we don't have a steady supply, even though is the most abundant element known to man. The current best ways to get it are by steam reforming of fossil fuels (no better than just burning the oil as fuel) or by electrolysis - a process which consumes more energy than the separated hydrogen can produce. It can also be captured from thermal decomposition, but again, that consumes more energy than is released.

Of course a car can run on hydrogen or propane or a bottle of your farts (If the engine is converted properly). A car can also run on coal, human feet, or even burning hotdog buns. The point is that it is impracticable and pointless.

Kurt, this is for you and all the "Nay Sayers" that have taken to time to comment.

Apparently you read a book that said "All knowledge Shall CEASE advancement", and took it to heart.

Inquiring MINDS never stop inquiring because previous inquiring minds never topped asking.

A well known Physicist wrote a 'textbook' on Physics in 1937 that contained the latest knowledge at the time.

In 1949 he wrote a sequel that contained the latest knowledge on the subject.

Two entirely different books.

HE Never Stopped Thinking.

Advances in knowledge come from those who THINK instead of those who openly declare the thoughts and ideas of others that disagree with their personal mindset to be unthinkable and a waste of time.

The very concept of INSTRUCTABLES is based on minds working together to find ways for people to improve their lives and Minds.
This is accomplished by the sharing of ideas and knowledge gained through their own efforts and observations.

Incidentally, the Physicist died in 1971 with an entirely KNOWLEDGE and UNDERSTANDING of the wonderful world of Physics.

He never assumed that his knowledge was complete and without error.

You might give it a try.

I am all for advancements and changes to our knowledge base of the universe. I never stop questioning and learning. This is not a simple matter of believing I know all there is to know - not even close. This is a simple matter of knowing that what you imply is not possible. Yes, Instructables is about a community helping each other to achieve greater things, but part of that is through criticism. When someone claims something that has been thoroughly tested and debunked, or otherwise goes against well established knowledge, that claim should be refuted.

If the devices you talk about were possible, they would instantly solve the entire energy crisis of the world. Forget automobile efficiency, this could power anything and everything. The fact that it is being targeted at low-income, low-educated people should be enough to alert red flags. I bet they have cure-all-snake-oil for sale as well. Do you honestly believe that some random guy (with no education in chemistry, physics, mechanics, or electrical engineering) could create something that world-class professionals cannot replicate?

This entire comment thread has gotten a bit uncivil, and I am also apologetic for that.

You seem to be familiar with engine mechanics, so let me try to explain what is going on. First, consider a gasoline powered electric generator. An engine burns gasoline. The potential energy contained in the gasoline is transformed into a rotational motion as the engine turns a rotor. This rotor then turns an alternator which (through electro-magnetic fields) generates an electric current. You can plug appliances into the generator. The more current drawn from the generator, the more gasoline it consumes. So far so good?

Now, what if the generator was retrofitted to be powered by an electric motor rather than a gasoline engine. The electric motor could also turn the alternator to generate an electric current. So, could the electric motor be powered from the generator itself? Absolutely not - this is a perpetual motion machine! It is impossible for the generator to produce enough power to turn the motor that is turning the alternator which creates the electric current for the generator itself. Energy is wasted as heat, vibration, and other such things.

Now, back to the issue at hand. Adding hydrogen to the oxygen in an internal combustion engine can increase performance. Oxyhyrdogen has been used in industrial equipment for this reason. However, the energy required to generate the gas will ALWAYS exceed the energy released during combustion. This is a fundamental principle of the universe. It is the exact same reason the generator in my previous example cannot power itself.

With that said, if you want to generate hydrogen at home via renewable energy (solar panels, wind turbine, etc), compress that gas in a tank, and then connect that tank to your car, go ahead. You will have an increase in performance and a decrease in fuel consumption. A lot of research has gone into the efficiency of storing energy from solar panels and windmills in hydrogen as opposed to batteries.

However, the hydrogen CANNOT be generated directly by the engine itself, or the system will decrease in efficiency. This is the first law of thermodynamics - it's also how the entire universe works.

Consider this, could you put a large pinwheel on top of your car so that the air passing through and spinning the pinwheel generates electricity? Sure, why not... Can you then use the electricity to power the vehicle, or in anyway increase its efficiency? Not at all... The excess drag on the vehicle with always be more than any gains from the wind energy, even though it seems "free."

This is exactly the same reason these "increase MPG with brown's gas" devices are scams. The generation of the hydrogen will increase fuel consumption which offsets any gain in efficiency that might be possible from the oxyhydrogen combustion.

I should also add, hydrogen fuel cell technology is a TOTALLY different story. It has nothing to do with internal combustion engines, but rather captures the energy released when combining hydrogen and oxygen to form water. This is converted to electric energy which turns a motor. This is also almost the exact opposite process as the electrolysis used in this instructable to produce hydrogen.

electrolysis breaks water into hydrogen and oxygen by breaking the bonds between the atoms. if you then take that perfect stoichiometric mix of H and O, and ignite it with a spark, there will then be a release of energy as the bonds between the H and O reform. the kicker is, less energy is released when those bonds form, than is needed to break them in the first place, a net loss of energy.

on the other hand, lets say you had a cheap way of producing and compressing hydrogen gas, lets imagine for now it's running off solar power and getting the water from a stream or lake, so you don't need to add anything to this theoretical hydrogen bottling plant. if you carried a bottle of pre made compressed hydrogen, and injected that into your fuel mix, that actually could improve fuel economy, because you're not creating an extra load on the car's electrical system to produce the gas you're burning. but even then, the savings wouldn't be great and would be unlikely to be worth the costs of the equipment to make the bottled hydrogen, or the modifications to your car necessary to properly burn hydrogen as a supplementary fuel ala nitrous oxide. we all like the idea of getting something for free, whether it's lunch, fuel, energy, or a science lesson, but when what you "want" isn't reasonable, sensible, or even possible, it's time to move on, not defend a flawed idea because you want it to work.

2 days ago

<b>if you then take that perfect stoichiometric mix of H and O, and ignite it with a spark</b>...

You will be disappointed because there is insufficient Oxygen to allow combustion to occur.

You just compared a combustible fluid to a non-combustible fluid, then claimed there is more energy in the combustible fluid per pound.

But, while we're on the subject, what is the amperage of the generator I am already driving?

And what would the resulting loss in horsepower be?

What would the ultimate cost in fuel mileage be in my circumstances?

So far, I am the only one working with known numbers and all the 'naysayers' are declaring 'superior intelligence' when they are working with 99% unknown variables.

And yet I am required to "be nice".....

2 days ago

you know, you're right that i don't have all the numbers, but i don't need them either. for any given horsepower of engine and amperage of alternator, adding extra load to the system requires more power be put in, and that power has to come from somewhere. if you're using a leaned out mix of gasoline or diesel plus hydrogen and oxygen gas, and that's exactly what proponents of these systems always describe, the fuel being input to the cylinder for combustion has a lower overall energy density than pure gas/diesel fuel, so you therefore need more of it to do the same work. that's just chemistry and physics, that's literally how the world works, you're exchanging energy for work, minus losses from heat, friction, etc. if you ask a system to do more work, you need to put in more energy, this principle is one of the tenets of thermodynamics. energy does work, and you can't create energy from nothing, it all comes from somewhere.

with an electrolytic cell added to a vehicle, you're making the system do more work, in the form of breaking the molecular bonds between hydrogen and oxygen by way of electrolysis. the energy to do that has to come from somewhere, and you need to account for losses to to less than perfect efficiency. this means even if you could perfectly capture and use 100% of the energy released by burning that H and O alongside your fuel(and you'll never see 100% efficiency in any mechanical system), you're still at a net loss because the electrolysis itself isn't 100% efficient. ergo, in our imperfect world, adding this electrolytic cell to an engine can only lower the overall efficiency of the system.

How large of a unit would I need to build to help an F-250 Powerstroke get better mileage?

none, no size of unit could increase the fuel mileage of your engine

would the effort result in more MPG?

no, it wouldn't. and i don't need to know a thing about your truck, its engine, or its alternator, other than that they exist in the real world where heat and friction losses exist, to be absolutely certain of that fact.

i'm sorry if you feel i'm being somehow rude or insulting to you, all i'm doing is answering the question you asked and explaining the principles behind my answer, based on scientific fact and natural, physical law. if you dislike the answer, that's a shame, but but the basic laws of physics aren't exactly a matter of opinion or interpretation, they are, observably, what they are.

So in this magic car ... is the exhaust captured and fed back into the "hydrogen generator"? If not, they're wasting the resultant water for no reason, and if so, it's clearly a perpetual motion machine.

No Paul, you didn't get baited by "trolls", but the jeen*yusuzs that failed to comprehend my question learned what it's like to clean the spittle off their computer monitors.

There is more in play in my simple question of how much Hydrogen gas would I need to increase my fuel mileage.

In the process of shoving their failures to comprehend i learned a lot about some "I'M SMARTER THAN ANY OTHER LIVING CREATURE" posters.

But, in the long run, it was interesting to watch the temperamental screeching.

This site has a be nice policy but so far it's really difficult to be nice here. I would imagine anyone posting anything here wouldn't change your mind, but honestly, you really should do some research on energy sources. How energy is converted from one source to another.

Yes, you can create a car that runs on Hydrogen, it's been done and done well, but you cannot make a car that runs on water converted into hydrogen on the "fly" (enclosed in the engine by itself without outside sources doing the conversion) it is not possible, you need energy to convert water into hydrogen "H20" is water.. The car you are referring to claims to do this with the help of the gasoline engine...

This is just basic science.

Each water molecule has two hydrogen atoms and one oxygen atom, each hydrogen atom is attached to the oxygen atom with a polar covalent bond, you need to split off the oxygen to create pure hydrogen, doing that takes energy, which by the way currently takes more energy than you get out of it. and at best, a perfect system (of which there will never be one) it will be 99.9% efficient and never a net gain. If we could freely convert H20 to hydrogen we would have unlimited energy on the planet right now.

You can simply do a google search to prove yourself completely wrong.

Stanley Meyer disproved Faraday by inventing a method to break water into its basic gases of Hydrogen & Oxygen, at a WHOOPING 1600% efficiency. This permitted him to run an engine on water, because he needed very little energy to run his gas generator. The reason why this has not yet come out into the open is anybody's guess. Read between the lines and you might get the answers.

2 days ago

You do know that Stanley Meyer was convicted of fraud, right? He wasn't a scientist. He had no idea what he was even doing. His numbers, measurements, and results are wildly inaccurate. Efficiency cannot be greater than 100%. In practice, efficiency cannot be higher than 99.999%.

The only thing Stanley Meyer proved was how gullible the average person can be.

I agree with everything you have said, and I have read thus far, but I have one question. Wouldn't the amount of energy provided by the combustion of the gas be increased because it's a mixture of Hydrogen AND Oxygen gas? Or does the presence of Oxygen just merely facilitate the Hydrogen's ability to combust?

Fantastic instructable and very amusing discussion. So full of of life. And grumpy old goat don't use a calculator or a science book. Build a hydrogen generator, fit it into your vehicle, feed your air inlet with the mix of hydrogen and oxygen gas mix and watch your exhaust, the feel when you accelerate, and your wallet at the end of he month. Simple. Oh and btw for a 2.5 litre engine you should produce about 8 litre gas per minute. I dont know why and how BUT IT WORKS. I get it daily proved what ever science is telling but I don't have rus coming out of the exhaust of my jeep any more. It seems to help to burn the fuel more effectively which is a win already.

How many gallons of water must my vehicle carry to generate 8 litres of hydrogen[gas] per minute? Since water weights 7-8 pounds per gallon how will this extra weight affect fuel efficiency? If I am on a trip will I be stopping for water more often than for fuel gas /diesel? What will my mileage per gallon of water be?

Thank You!

So, for a 7.3 I would need about 24 liters per minute.

For my first generator I used 14 stainless steel sheets 4"x6". They produced about 16 liter gas per min. Without any electrolyt in the water. I would say try the 14 x 4"x6" and add some electrolyt and you should be fine for your 7.25 liter engine. I addded a second alternator and a second 95 amp battery into my vehicle that actually does the trick. These generators are quite power suckers. ;o)

I already have extra batteries, and the generator is far above the 'factory' model.

I figured the draw would be serious and was planning on controlling both the electricity and the current to see if it could be tweaked to provide a better return on investment of energy.

Thanks for the help. I think I'll double the length of the plates for more surface area.

That should help with the amount of current required.

So, maybe I missed it, but there is no separation of oxygen from hydrogen in the gasses produced (I mean, while you're producing both gases, you're not filtering one from the other). This is extraordinarily dangerous if you attempt to store any significant amount of gas. Electrolysis rigs generally try to separate the two gases via filtration, which is difficult but necessary if you're going to store the gases for any sort of bulk use.

If, however you're making the blend and burning it immediately in small batches, then go to town.

Very interesting idea i like this very much

hugbear16 hours ago

Why do people insist in getting the electrical energy necessary for electrolysis from the same source (petrol) the're trying to save? Focus instead on recovering the vast amount of THERMAL energy that is basically wasted. Try coating the engine and exhaust with Peltier cells using the Seebeck effect to extract usable electrical energy and you would be on a right(er) track. It's not perfect, it might not generate enough HHO for the engine's need but at least it won't be trying to pull itself up by the bootstraps...

2) 'new way to power automobiles"...been around for a while.

3) Our education system is failing badly. The technique to separate water into H and O is generally termed electrolysis. My 6th grade science teacher did a similar experiment. I went home and duplicated it. My 11th grade chem teacher taught me the chemistry behind it. My 11th grade physics enlightened me about the laws of physics, particularly energy balance and energy transformation (note: it is a 'truth' that energy cannot be created or destroyed...only altered). My hs/undergrad school math teachers gave the me tools to express observations into quantifiable 'truths'....just like the previous experimenters: Ohm, Faraday, Ampere, Coulomb, Heavyside, Maxwell, Rutheford, Boyle, and many, many more.

4) just because one makes a claim about a very small subsystem, doesn't mean the same claim holds when the entire system is considered. Learn to do analysis of the system.

Lastly, simple solutions is usually just that....simple.

Maybe the "King" should rewrite this and put the note paragraph at the top instead of the bottom.

"NOTE: The amount of electrical energy required to make the gas is more than the energy you can obtain from it. This is NOT an energy generator so much as it is an energy converter."

This is only cost effective if you can use solar to start and maintain the process. And not in this model. The alternator does produce electrical, but at the cost of fuel. The alternator is designed of chosen for the engine its mounted with. Adding an extra large load will cost you in the end.

There are schematics and plans out there that use circuits instead of raw voltage. Those are better but still have a loss across the production vs need curve. The solar panels in this setup will produce enough to start and sustain the reaction needed. You will need some special equipment to make that happen as it requires some waveform tweaking that you cant just eyeball.

Now here are some lessons learned. This can be done on the car your driving right now as long as you have a mechanic willing to do it. There is danger if you do it yourself. If your intake isnt mixing the gases in the right ratio, your at a loss. If you put too much in the intake, you will burn your cylinders or blow something up that wasnt meant to be. I am not saying treat it like a nuclear reaction, but treat it safer than you would gasoline.

Things needed for this to be marketable:

Flexible solar panels. Which as I understand are available. \$\$

Electronics technician. Hire a good one.

Auto mechanic. One that understands the science of fuel to air ratios before start.

Venture capitalist. Because I cant afford to do the research anymore.

yesterday

You can not use solar as you will not gain enough energy!

PV cells typically give less than 12%, an electrolyser less than 65% efficiency while our best domestic internal combustion engines are only 30% efficient (regardless of fuel type or mix) so we'd end up with a 2.4% fuel efficiency from our rather massive solar array which our vehicle will have to drag along with an equally large industrial electrolyser (some real tonnage here).

If we combine hydrogen systems with conventional fuel systems we simply increase the mass of the vehicle, which in turn requires more energy to accelerate which equates to lower fuel efficiency and greater running costs!

To put hydrogen and gasoline into relative perspective, 1 kg or gasolene contains 45 000,000 joules of chemical energy while stoichiometric gaseous mixture of O2 and H2 only contains roughly 45000 joules, a thousand times less energy!

To get an understanding of energy density 1 Kg of gasoline is 1.33 litres while the equivalent (in chemical energy terms) of stoichiometric gaseous 02 and H2 mixture has a volume of 11958 cubic meters! So assuming a 10 liter gasoline tank (I know this is a little small) and assuming we just carried our H2 and O2 gas, to get a 10% reduction in gasoline consumption using an 02 H2 mix at atmospheric pressure we need a fuel tank that measures 22x22x22 meters. To put it another way anyone claiming that they reduce their gasoline consumption by using any sort of hydrogen oxygen gas generator will need to generate a proportionate volume of gas to support their claims.

Looking in another direction, to produce an H2 O2 gaseous fuel that is worth the same in energy terms as 1 kg of gasoline we need to start with 1000 kg of pure water (plus additives), me thinks a 150 year old steam engine looks more attractive.

yesterday

Thanks for stating the math that I didn't. No one seems to be interested in it so I decided to stick with the easy parts. Which as I scroll through few people accept anyhow.

I can argue you on using solar panels however, I wont because I currently don't have any of the supporting documents on hand, and don't feel that it would be productive. I cant build anything right now to work out the proofs either.

If you do some digging and cross reference different research still going you will find some electronic circuits that have proven effective at lower voltage and amperage. Systems with draws low enough to be supported by solar panels. Not cheap panels, but good quality producers.

So again, it boils down to cost. And its still an overall loss situation. Overall cost versus use life of equipment.

Thanks for agreeing in a different way.

Lol...you've heard of hydrogen powered cars right? Well they use hydrogen and oxygen as fuel, and the only thing keeping them off the streets is the safety hazards of compressed hydrogen. Once a safety method is configured around that, this will be used in most likely every future car. "Electric cars" are simply a stepping off point, they won't last.

Yeah, I'm aware of them, but it takes more power to split the water than what you will get back from the hydrogen produced in addition to hydrogen being very unstable.

The biggest problem is not only safety issue, but the energy density of hydrogen or oxygen is so much ridiculously lower than fossil fuels. You will need to burn up a couple grams of Hydrogen and Oxygen to get the same energy from just burning a microgram of gasoline.

No, what none of you seem to understand or willfully ignore is the fact that it takes more energy to separate out the hydrogen than you will ever get back by burning the hydrogen as an energy source. In other words you will spend \$10 to get \$5 in return. Does that seem like a smart thing to do?
11 months ago

After you buy the solar panel, how much does the sunshine cost that will make \$5 worth of hydrogen? That's right, zero.

Take the cost of a solar panel, about \$1 per watt and divide it by the energy generated over the lifetime of the panel. So, 250 watts, costs \$250 to purchase the panel. It produces about 1250 watt-hours per day on average. That's 1.25 kWh, at say 16 cents per kWh or about 20 cents, per day, times 365, times 25. \$1825 of electricity for \$250. Pretty good. Even when I get \$912 worth of hydrogen, it's still good.

So \$250 per kWh divided by 11,400 kWh = 2.2 cents per kWh. or perhaps 4.4 cents per kWh of the equivalent amount of hydrogen. Still great.

Solar panels are expensive and fragile to be installed in a vehicle. A simple alternator in existing engine system can do the work to sustain the HHO production while charging battery. Though, to start the system, it uses battery charge.

Exactly right. This system has been used to power vehicles already. There's a huge amount of Internet lore concerning the patents, the buyouts, the lawsuits, the conspiracy theories etc. surrounding the hydrogen engine. Pour water into the engine and go,it's real. Anyone who simply says "if that existed, we'd be usin' it" is blatantly ignoring the HUGE leverage of the existing petrol industry to continue the use of fossil fuel burning machines of all kinds.
3 days ago

...and you're ignoring the fact that fossil fuels are simply much better fuels than hydrogen - far more energy-dense, far easier to handle, much less explosive, much easier to store etc.

Unless you split the water using solar or wind power, this is an incredibly expensive way to power a car.

yesterday

Solar and wind are effective when used to generate electricity, very very poor in efficiency terms creating hydrogen that then needs expensive and careful storage.

yesterday

As far as generating hydrogen is concerned, the source of the electricity makes absolutely no difference to the efficiency.

As for storage, that is a different discussion.

yesterday

Well overall efficiency has to take into account all the inputs, true the efficiency of a single stage can be quoted in isolation, but leaving aside all the pretend physics that some are quoting, the most important aspects to consider when choosing an energy source are economics, and engineering potential (I assume we always cover safety and the environment). If we use a solar panel to farm energy we have a choice in how we use the electricity generated. If we burn it in an engine and look at the overall efficiency we get a chain of percentages due to electrolyser efficiency:storage processor efficiency:distribution efficiency:end use efficiency. In contrast we could simply generate electricity and try to distribute that, which results is a better overall efficiency (though grid balancing may kill any gains if we are not careful).

The engineering potential of a successful hydrogen economy is not all that great currently. Hydrogen in liquid form is extremely hard to distribute, if you pipe it you need to insulate the pipes otherwise a great deal of your energy will leach away as heat, bottle and tanker distribution burns yet more fuel. Local production equates to massive multiplication of efforts. Granted there are a few hydrogen refueling stations with us already (California), these are all bottle fed by trucks with the hydrogen itself either steam reformed, gasified or electrolysed, very little of it bears any renewable significance and the true cost of the energy is likely buried under a pile of environmental subsidies.

Here's that 'more energy' phrase again! Do you know how much potential energy is in a molecule of hydrogen? It's not a matter of 'more', energy is energy. It's a matter of conversion- period. Can I use an abundant, replenishable source of energy to convert to usable energy for my application? That is the question. Nothing in the universe as we know it can make more than what's there...that'd be magic. Harnessing existing energy is the name of the game. You know the sun produces immense amounts of energy, certainly enough to 'potentially' power every car on earth. Unfortunately, nobody has built the perfect engine that runs on sunshine. I imagine that when the first guy looked at a waterfall and said, "look at all the energy, let's harness it somehow and power a large city" there were people lining up to tell him how impossible that was. If we stay around long enough, someone will read these comments and laugh at the idea that we drove cars on petrol at all. Columbus was going to fall off the edge of the world. Disease was bad spirit. And on and on. It's easy to say now that this or that can't be done... Until it is. Our ability to convert hydrogen to usable energy may be inefficient and unstable,etc. right NOW. But technology paired with forward thinking produces results, and it's only a matter of time.

Actually very few people with any significant wisdom ever told Columbus that he'd fall off the world, few still would have ever doubted the possibility of powering cities from waterfalls. But it is very unlikely we'll ever find a cheap way to convert water to usable hydrogen, physics supports this.

I think he was implying that building a solar powered fuel cell generator at home, then using that fuel in your vehicle would work. Not that you would generate your own fuel on the road.

Your alternator is powered by the fuel, at a low efficiency. This fuel is generated by electricity, at a low efficiency. So using your fuel to generate more fuel is so inefficient as to be a complete waste of time. The added work generated by adding load to the alternator would never come close to being recouped.

No it would not work, because the structure required to pressurize the hydrogen is just a little expensive and dangerous. One would have to tow a tank trailer to have enough hydrogen gas to run a vehicle 100 miles or more. A large tank.

when talking about generation of power, you begin with no more than 0.5 of unity output. since 50% of the power is consumed by, the source generator. so you are starting off with a 50% reduction to begun with. with 50% maximum, left to work with. and combustion engines, are typically less than 25% efficient. and steam turbines, as high as 67% efficient. and you always loose power, generating electricity for powering anything. unity generation and consumption is an improbable dream of perpetual motion, and over unity is an impossible dream.

If the alternator makes electricity that fuels the HHO production, the alternator will have extra resistance, which will further tax the engine and burn more fuel. I agree that the HHO might make the combustion more efficient, but the electricity is not "free." It has a cost in gasoline as the alternator has more resistance. Energy cannot be created or destroyed, and it just moves around. Solar panels have been on vehicles for fifty years, including vehicles in space. Solar car races happen in multiple places every year. Anyhow I was not thinking of HHO for car engines in particular, but in general for a fuel for other purposes.

4 days ago

Sure, you could dump some of that energy into making H2, and then use a bunch of that energy to compress the H2, and then build a car to run on the H2 (it takes a LOT of energy to build/convert an engine), and then waste a bunch of H2 on an inherently inefficient motive source, i.e. an internal combustion engine. Or you could use the electricity to run an electric car ... which makes more sense?

doubtful you will get 25 years of service, from any solar panel. especially in areas prone to hail, and lightning strikes. and the panels, loose efficiency over time. then there is the problem of the toxic substances used to make, solar cells.

even using a mirror array, to make steam to run a generator has maintenance problems. but it, may be a more viable solution. since solar cell transducers, are less than 21% efficient. however adding a thermopile, to each solar cell could increase output. but also an increase in production price and cost.

4 days ago

Correction jimmie.c.

Barring lightning (and I've never heard of a solar array getting hit anywhere in the world) there's no reason well-built panels can't last virtually forever.

Certainly rate of conversion will decrease marginally, but such deterioration isn't nearly as great as in, say, your body. (and pv panels don't grow beards, either!)

There are "toxic substances" involved with the production and maintainence of just about anything you can name: including people.

.......AND they don't work as efficiently as pv panels ( the efficiency of which is about to nearly triple in the foreseeable future.)

I put up my first panels in 1982. They were 2nd hand Unisys rated at 45 watts the second-biggest ones available back then. (and I paid \$13.80 per watt for them ~ not cheap 30-odd years ago.

Point is they're still producing up to 36/38 watts on a good day ~ by a friend of mine who lives at altitude (cold climate) in a smog-free area.

These days good pv panels cost bugger-all, and any drop in production is easily compensated for by mounting another panel ...or six.

The real problem has always been storage: cost of, in terms of resources AND cash. But as more and more people (and governments!) look to alternative power those prices have come down dramatically and new technology in the pipeline will bring price and efficiency to a level as reasonable as is deemed acceptable in any other product. (and MUCH better than the cost and efficiency that can be achieved by human bodies. (particularly the hairy ones. ;) )

And though I'm a great fan of appropriate technology I'm still convinced that the KISS principle should always be the benchmark.

Lets do some math. 1 watt is about 1/750th of a horsepower. Even assuming that the solar works 12 hours a day but you only drive 1 hour/day you still need 7500 watts of cells to get 1 hour at 100 horsepower.

Plus you haven't taken into account the HUGE amount of energy required to compress the hydrogen to make it possible to carry enough to actually run an engine for more than a faction of a second. Energy used to compress the fuel is wasted energy. I leave it to you to look up the power specs to take say 10 kilograms of hydrogen at atmospheric pressure (which is what the hydrolysis cell will produce) and compress it enough so you can carry it in a tank in a car. 10 Kg of H2 is about 10Kg/2Kg*22400Liters at STP. So you are starting with about 100,000 liters (roughly 25,000 gallons) of H2 at STP. So figure out the cost to compress that 25,000 gallons down to say 10 gallons. Your final pressure will roughly 2500 atmospheres (ignoring liquifaction).

If any of these electrolysis scams actually worked every car maker in the world would already be using them. Car makers are scrambling to boost mileage by fractions of an MPG and they'll do a lot to pick up 0.5 MPG (like under sizing the battery). The first company that sold a car with these "magical" systems would dominate the market (if they worked) since fuel economy is a HUGE selling point. Within a couple years all car companies would be doing it. Since this hasn't happened that provides IRREFUTABLE real-world PROOF that the whole idea is a giant SCAM.

MichaelH5 That is a totally illogical argument. More than that it is just not smart. If the hydrogen generated by solar costs nothing, then electricity generated by it cost nothing. Run the car on batteries and electric motors. It costs far less to make an electric car than an engine that will run economically on hydrogen. Plus the tank and associated hardware to run the car on hydrogen are large, expensive and not safe.

6 months ago

On a closed-system, the energy absorbed by the HHO during electrolysis is equal to the amount of energy released during oxidation. The actual energy loss is at the electrolysis device. But, internal combustion engines use atmospheric gases energized by the sun 24/7. As HHO and Atmospheric Oxygen is mixed, there is a probability that the sun-energized oxygen is used to oxidize the hydrogen. That reaction, releases more power than what is needed to separate the hydrogen. Thus, HHO used in engines can release extra energy to run the alternator (to release more hydrogen) and enough energy to do work.

3 days ago
While that seems sound that my friend is a perpetual energy machine. Regardless if the gases DO make more energy than it takes to separate the engine will NEVER be near 100% efficient. That means that energy will be lost due to heat, light, and incomplete combustion. In theory it "might" work but IRL it cannot happen.
4 days ago

This is utter nonsense. There is no such thing as "sun-energized oxygen," and the combustion of hydrogen with atmospheric oxygen produces the same amount of energy as the combustion of hydrogen with oxygen from any other source.

Beyond this, there is an absolutely unavoidable, major loss of energy in going from gasoline to hydrogen by electrolysis and then burning the hydrogen. The heat released by burning gasoline can only be converted to mechanical or electrical energy at an efficiency of 30 - 40%. This is a fundamental thermodynamic limit. If you drive the wheels directly with this energy, that's your net efficiency. If instead you make hydrogen by electrolysis, even at 100% maximum efficiency, you still have another factor of 30 - 40% efficiency when you burn the hydrogen to produce mechanical power to drive the wheels. The maximum theoretical efficiency of such a system would be something like 15% of the energy in the fuel directed to the wheels, and an actual system would be very unlikely to capture as much as 10% of the energy originally obtained by burning gasoline (or any other liquid fuel).

These anti-scientific fantasies simply obscure the very important discussion we need to have about energy and its efficient use. If you would care to cite any reputable source for your fantast of "sun-energized oxygen," I'd be happy to read it. But there is no such study, because the idea is imbecilic.

Energy efficiency in internal combustion engines does not change with the fuel used. Efficiency is all about heat gradients. You have to get rid of the heat, and that take energy.

H'lo again chastjones,

Ok, so you're telling me that you'll end up with just as much water to create HHO as you started with after the HHO has burned? Alone, HHO is a combustible mix, but it will still come into contact with the atmosphere at some point during it's combustion. Since our atmosphere is a blend of oxygen and other gases. When HHO burns it also burns the nitrogen, releasing various oxides of nitrogen as well as what's produced with the various other gases in the atmosphere. I do not believe it to be possible to end up with the same amount of water to create HHO as you will after the combustion of that same HHO.

10 months ago

Assuming that no free hydrogen escapes to the atmosphere un-oxidized, then yes, you will end up with exactly the same number of water molecules as you started with. If some of your oxygen ends up reacting with carbon or nitrogen or some other element then free oxygen from the atmosphere will be required to completely oxidize the remaining hydrogen.

I think some people are missing the actual benefits of hydrogen.

It is non-toxic. It readily combines with nearby molecules, so spills are never an issue as far as toxicity like petroleum. While it is bound up in other molecules, it is still the most abundant element in the universe. Which is why it is not pursued: it is not a commodity, and cannot be controlled as readily. Remember what happened to Nikola Tesla when JP Morgan found out he was researching to produce devices to broadcast electricity that people could "pick up" out of the atmosphere on an antennae. No more funding.

Hydrogen is portable as a storage mechanism, and can be transported to where it is needed, like electricity, but in tanks, or pipelines. It can be made with solar panels and water. The technology costs, but the source of energy in this case is free, minus the catalyst, which is negligible in cost.

It really is not a "fuel" in the sense of gasoline. it is not refined, or drilled out of the ground. it is not found in deposits, except in stars like our sun. And it does take more energy to make it than it puts out. That's OK, we do that every day. Only about 42.25% of the total energy we put into the US energy chute makes it to an end use.

http://www.sankey-diagrams.com/wp-content/gallery/o_gallery_205/bloomberg_energy_sankey_1.jpg

But this HHO is recyclable, from water to HHO to water. Some of the oxygen is lost to nitrous oxides, but there is other oxygen in the atmosphere to combine with the hydrogen to make water again. The amount of NOx is small. With a sealed fuel cell it does not combine with the nitrogen in the atmosphere.

Hydrogen is an elegant energy carrier. We still need something to generate that electricity, but dams, wind generators, wood, and solar panels are renewable sources which can produce a portable fuel in HHO or hydrogen. Efficiency only plays a minor role.

sea water wouldn't be ideal because the salt would corrode the engine to quickly. You would have to install a desalination unit which would use even more energy to produce the hydrogen. In a pinch at the beach I would say a gallon wouldn't harm it to much. Or even deep in the woods I would say urine would do.

that kind of doesn't make sense. If water is 2 parts hydrogen and 1 part oxygen, and you separate the two and then burn the hydrogen wouldn't you only have oxygen left over?

10 months ago

Well the word "burning" suggests that something is destroyed. This is true with a fossil fuel in that the process for "burning" or oxidizing permanently changes the fuel materiel. Remember, Oxygen must be present for anything the "burn", Hydrogen is no different. When hydrogen is burned it must combine with oxygen at a 2 to 1 ratio. This is because oxygen's valance is -2 so to fill that -2 shell it needs 2 electrons and since hydrogen has only 1 electron it take 2 hydrogen molecules. Rather than use the term "burn" it is more proper to use the term oxidation which more accurately describes a chemical reaction. So, using chemical or electrical electrolyses you liberate hydrogen and oxygen at exactly a 2 to 1 ration and when you oxidize hydrogen the reaction results in the release of heat energy (exothermic reaction) and the recombining of the hydrogen and oxygen in exactly the same ratio 2 to 1 which we know is just water. Neither gas is every destroyed in the process. The only way to destroy either of those two elements or any element for that matter is thru a nuclear reaction (fission or fusion).

law of conservation of matter: matter cannot be created nor destroyed, only displaced or converted. He is not saying that nothing is being used. Water is converted to its basic parts hydrogen and oxygen. They are volatile. Catalyzed with a spark a hydrogen breaks its H2 bond and forms with the oxygen forming oxygen as an exhaust. Also, that BS about "taking more energy to produce than it a generator can make" can be fixed by just putting an alternator on the engine to generate more electricity to replenish the battery/batteries. They also have these magical things called pulse width modulator that keeps a perfect stoich for this kind of reaction. This is a perfectly good idea, I have seen people run trucks on this idea. You will see this in the future.

I love all the squabbling here over this tech. Which has been oft discussed in the popular press and isn't ready for prime time. This is a cool project, not a way to power your bunker, guys. As for energy loss? All energy on Earth starts as sunlight. Oil is an extremely inefficient use of that, just as eating beef is. But using solar, which we have plenty of, to cycle water as a fuel, has great potential for the future - when the tech is ready! This is pretty much the science. Learn it so you'll understand hydrogen when it finally hits the market.

It doesn't run out. Split water into HHO, burn it producing (mostly) H2O, and re-use.

Plus Earth has a truly unimaginable supply of water. It's everywhere. Even in a desert, using a solar still water can be wrung from thin air. (Probably not enough to power an engine but it IS there.)

Can't say that for oil - even if some of the oil is found in desert regions!

You can't split water into HHO, the process splits water into H and O. Hydrogen and oxygen.

Your statement, "It doesn't run out. Split water into HHO, burn it producing (mostly) H2O, and re-use."

If "producing (mostly) were true then indeed the water would run out.

Electrolysis produces hydrogen (H or H2) and oxygen (O). Then burning releases the energy introduced by the electrolysis process and recombines the H2 and O into HH0 which is an alternative way of writing H2O.

The only energy actually released by the process is the additional energy gained from the electricity. Energy in the form of electricity is used to separate the hydrogen from the water. The energy in the water is now in the H2 and O. All of that energy is used up by recombining the hydrogen and oxygen. While the energy of the electricity is used to power the car.

It is not possible to take water, break it down and then recombine it and get any energy from it, unless additional energy is introduced.

If one burns hydrogen from another source, then it would seem that the car is being propelled by the hydrogen. What actually happens is that the free hydrogen and atmospheric oxygen have more energy than water. Either the additional energy from electrolysis or the energy used to create the hydrogen in a far away place. When the hydrogen is "burned" or recombined with oxygen, this additional energy is released. The hydrogen is still there in the water. As some have said it is an energy conversion process, but the conversion process requires outside energy.

4 days ago

You do have a true understanding of this. People that put these hydrogen generators on there car is just converting more fuel into electricity and then using that electricity to convert water to hydrogen gas just to use as fuel energy that was taken from the fuel(gasoline) in the first place. It really does not improve the power from the engine and because of all the conversions, energy is lost in the form of heat in each step of conversion.

Over 75% of the planet is covered in water, much of it already has an electrolyte in it to speed this process. NACL . Seawater is H²O with NACL and other minerals in lesser amounts, perfect for use, though a bit (quite a bit) corrosive. The thoughtful use of stainless to avoid excessive corrosion of plates is good. Use of a solar panel generating 15VDC would be good. I don't see a downside. Energy from the Sun, breaks down the water into H² and O² channeling O² and H² to compression and use in a vehicle. Cleanest means of powering a car yet. Only product is water for the exhaust. No CO² or hydrocarbons emitted.

As Hydrogen/Oxygen fuel cells are now viable in cars, that's not too difficult..

It looks pretty good. Compression and storage of the gas would be the only thing I'd go commercial on, for added safety. You could get licensed to sell fuel cell filling.... You'd only have to contain & compress the H².

That is the beauty of HHO, its self replicating. The engine burns the hydrogen thus expelling it to the atmosphere producing more water. Let's see what gas does for the atmosphere lol

Well that sounds good. The problem being that electricity has to be used to make the hydrogen and the process used to make electricity does create emissions in the atmosphere. Even if nuclear fuel is used to create the electricity, emissions into the atmosphere occur is the gathering and creating the fuel.

Plus the creation of hydrogen from water and electricity is a net loss in energy conversion. Just use the electricity to run an electric car. That will create fewer emissions that creating additional infrastructure to make the hydrogen, store it and pressurize it.

Making hydrogen from electricity and water necessarily has to be less "green" that just using the electricity itself. LOL

The beauty of hydrogen powered engines is that hydrogen is NOT a power source in itself, but rather a way of storing energy: you get hydrogen by the electrolysis of water, then when hydrogen is used it's converted back to water.

As this is a cycle, water would not be finishing as it is "recreated" the exact moment hydrogen it's used. In order for water to finish one should either store the hydrogen indefinitely or ship it off outside our planet.

The biggest problem is that you need more energy to produce hydrogen than what it will give you back, this making electric cars a better solution in the medium term. I heard talking about hydrogen cars in the mid 90s for the first time (a Swiss made the first prototype), yet 20 years later we still have no hydrogen car anywhere nearby commercialization.

Why would the water run out?

10 months ago

the water will never run out because the car spits the used water back out. Or as RolanC suggested recapturing the water and reusing it. Altho now that I typed it it has occurred to me that once separated from the oxygen and burned the remaining hydrogen would have to be re-oxygenated to become "water" again. So I would think that this system would need the separator and a joiner of sorts.

problems with your thinking, no matter what is the source of hydrogen. two molecules of hydrogen, combined with one molecule of oxygen always produce the same amount of heat.

plus you left out, the carbon bond with the hydrogen associated with fossil fuels. with carbon being, more inefficient than hydrogen. especially when it tends to become, carbon monoxide rather than carbon dioxide. without even getting into the inefficiencies of the oxides of nitrogen being produced.

one pound of hydrogen, will produce more heat than one pound of fossil fuel. and is even a more powerful energy output, than one pound of tnt or dynamite.

your using the gas as soon as your making it. you use the engine to suck the gas from the hose and the fuel cell is under a slight vacuum. there is no problem if grounded and no leaks where they shouldn't be. the hose is less than 1/2 dia id. you can just stop the making process by shutting off the electricity about 2 minutes before you shut the engine off. you are not trying to run the car on it your just adding a little bit to the mix. so your not understanding the way it is applied and the results by proper mixing.

No, what you are ignoring is that this is the case for EVERY form of energy storage. Please feel free to cite ANY exception. Good luck with that, as doing so would violate the zeroeth law.
Car batteries DO NOT store all the energy put into them. Electric generators do not output as much power as they receive. Fossil fuels do not contain even a tenth of the energy that went in to creating it. Refineries put even more energy into the process. Gas engines do not convert 100% of the energy in fossil fuel.

the volts used to run is less than 15 . and when mixed in the fuel you get a better burn. it cleans up the process. look up the properties of using water-gas torches and you find that the gas is strange in the way it works. using the same idea and not trying to reinvent the wheel the people who are caught up in science need to apply it to see what happens. new things are discovered when you apply ideas. don't get caught up details that may not apply to the situation. yes safety first complain less later. you are not trying to make a giant amount of gas here your just making a little to mix in to get great results. you can get confused when you have too much information. if your still a naysayer then don't even try to build one. just understand many will.

There are several things keeping hydrogen powered cars off the streets.

First and foremost, is the inefficiency of creating the hydrogen. If you're going to burn fuel to make electricity, and then use electricity to make hydrogen fuel, you might as just burn the original fuel to accomplish your task, and skip the electricity and the hydrogen in between.

The second bar to hydrogen powered cars is lack of infrastructure. This *could* be overcome -- notice how we're putting electric cars on the roads, even though *most* of the infrastructure is oriented towards gasoline and diesel. Electric car infrastructure is growing, but people started buying the cars back when they could (mostly) only charge them at home.

Third is storage. Hydrogen requires either cryogenic temperatures, or insane pressures, or fancy molecular adsorbents.

Fourth, hydrogen has a bad reputation. Who hasn't heard of the Hindenburg Disaster? Sure, you know and I know that it's no more explody than gasoline (which isn't saying much), but people think about these things with their guts, not their brains.

Making hydrogen, using hydrogen cells to separate the oxygen from the hydrogen and then introducing the hydrogen into the air intake of the engine does not require it to be compressed and if the power is cut to the cell all the cell has in it is water, couldn't be safer, far safer than gasoline, propane, natural gas. there is no fuel storage tank with a hydrogen cell. It can be used to enhance gasoline combustion or used all on it's own. To turn hydrogen into a storable gas would take about 5000 PSI or greater, I believe it is closer to 8000 psi . It is a very difficult gas to compress into a liquid storable fuel, and it doesn't need to be making it one of if not the safest fuel systems there is.

You don't think oil companies might have anything to do with it? You're talking about the disintegration of one of (if not thee) largest industry on Earth. I'm sure they are just dying to leave go of those trillions of dollars... Hydrogen powered cars are easily possible and viable. There are technical hurdles of course... and yes supplementing your car fuel does work, but so minutely that it isn't a noticeable improvement. There are actually elements much better than hydrogen as a fuel source. One of which is Thorium... look it up. Also, space rockets run on Hydrogen and Oxygen... Hydrogen is unstable but that is the point... so is gasoline. My buddy has a motorcycle with a sterling engine that runs on hot and cold water.

Doubt if it ran very fast or far. Sterling engines run on heat differential. It's not the water that runs them, but the difference in heat. And the motorcycle would only have as much energy max. as the energy in kcal produced by the small difference in heat. Not very blessed much. A sterling engine will quit running when this heat difference dissipates, so to run a motorcycle you would have to burn fuel to keep it running. It might run in a shallow ditch filled with cold water.

I looked into these systems a few years ago for my vehicle. Some people call it Brown's gas. I have a cousin who installed it on his truck and claims he gets higher gas mileage. With computer controlled ignition system nowadays, the computer adjusts the fuel consumption. By adding this additional fuel via the air intake, the computer detects richer mixture and leans down the consumption of gasoline. "supposedly". I've thought about trying it, but it never made it to the top of my priority list. Regardless of the claims that you don't save because you are using more energy to produce the hydrogen, I believe you still come out ahead. None of the people who take that stance have actually proven it to be true. Just talk. I remember when gasoline was 45 cents/gallon. It's 2.50+ now, but a year ago it was \$4. So, I think the amount you pay for petroleum would be the determining factor in deciding whether the investment in this system is worth it or not for a vehicle.

BTW- this was the most professional looking system I've seen. I think it would need some better mounting hardware for a vehicle, but good job!

The burden of proof is not on those who say you can't get more energy out of an energy conversion process than you put into it. That has already been proven many times over (nevertheless, there is proof below). The burden of proof is on those that think your car can break the laws of physics.

The issue I had with mine is that it wouldn't produce enough to make a difference to my gas mileage. Your car's electrical system has plenty of surplus energy to spare, but the biggest generator I made could only produce about 3 liters per minute of gas. To have any real impact, you would need to produce at least ten times that amount. As a motor fuel, this isn't really practical, but it's still fun to play with explosive gasses. If you have a deep freeze you can even get the oxygen to drop out and have pure hydrogen.

Also, since you can't use pure water for this, on a grand scale it could be a useful way of cleaning or desalinating water which (if we used it as much as we do petroleum) would certainly invigorate the water cycle and probably create a lot of precipitation. Of course then you have to deal with the waste/precipitate in your electrolysis chamber.

On the other hand, water vapor (in a given immediate area) exacerbates the greenhouse effect of CO2. So, there's that.

I've thought that it might make both electrolytic desalinization and hydrogen as temporary energy storage more economically viable if you included them in a single system. Assuming you are using some renewable source for the initial energy production, it wouldn't be net positive, but it might make for a handy on-site way to smooth out energy demand cycles while also producing clean water.

People on here keep talking about using "excess energy" from the alternator to make hydrogen. The energy it takes to make the hydrogen isn't excess. You are increasing the drag on the engine, via the alternator, to make the electricity to electrolize the water. The increased drag on the motor takes extra fuel. The resulting hydrogen physically cannot produce as much power when burned in the engine as it took to make. Even putting solar panels on the car to this end would almost certainly create more aerodynamic drag than you could make-up for. Nothing that spins or reciprocates on a car has "excess" energy.

Now, if you were using Peltiers on the exhaust or in-line with your coolant to produce the hydrogen, that might be worth it. But it would be more worth it to use something like that to charge your battery. If they were efficient enough (currently available tech probably isn't), you might even be able to get rid of your alternator and save quite a bit of gas.

We could make arguments all day about the viability of producing hydrogen with solar or wind power and so on. Maybe there's a place for it. But making it with petroleum or, worse, from the alternator in the car you are also burning it in, is an extraordinary waste. I promise you will burn much, much more gasoline per mile using anything like that method.

Yes, I recognize that solar panels don't have to increase aerodynamic drag. But I would hazard a guess that very few, if any, DIYers are installing perfectly flush photovoltaic cells on their body molding, and that's just about what it would take.

Hydrogen IC and fuel-cell cars are technically viable, but far from economical, and it has nothing to do with oil-company intervention. Besides the problem of on-board storage, the hydrogen has to COME FROM somewhere, either fossil fuels or electrolysis of water, usually -- the former is less efficient than using the fossil fuel directly, and the latter is MUCH less efficient that using the electricity, however it may be generated, as electricity. Hydrogen is hard to transport and store, and would require an infrastructure comparable to the multi-trillion dollar infrastructures already in place for natural gas, electricity, and crude oil & refined products. All without ADDING any energy SUPPLY at all -- hydrogen is nothing but a FORM of energy, and an extraordinarily inefficient one at that.

Hydrogen-powered cars are a very long-term solution at best. Much better is to increase efficiency (i.e., "mileage") of all vehicles, continue to add plug-in hybrids so we can drive short trips on electricity, use EV's and CNG for second / "commute" and local delivery vehicles, and change our BEHAVIOR (more use of public transit, "Zip" cars & conventional rentals, mass-transit, etc.). plus renewable fuels for long-haul trucks and planes where there is no good alternative to liquid fuels. Pipe dreams like hydrogen and utter nonsense like cars that supposedly run on water just detract from focusing on workable solutions.

You can use a pwm to control the leds pulses are use the cars output pulses to the injectors. What this does is primes the oxygen on the intake with light which the atoms nucleus will absorbe which in turn will push the electrons quantum orbital position outward making it much easier to strip off when passing trough the wire mesh grid that is connected to positive terminal.

Because they are working with the oil companies. Where do you think all the worlds hydrogen comes from now? Yep - the cracking of oil distillates. They are not stupid. Neither Toyota nor our polluting devious pals in oil. The argument could be made that it is a more viable transition to all electric cars as battery technology will still be expensive compared to burning oil distillates for some time to come. But given that the electric car WILL come of age and it is a movement that cannot be stopped - if you were an oil CEO how would you keep your profits from declining? They can put a hydrogen infrastructure in place tomorrow and they manufacture it in vast quantities already. We will still be consuming fossil fuels for years to come.

As an odd thought in the people for / against using it on cars:

One thing that can be good is that the HHO combustion occurs at a prodigious pace and that it is extremely resistant to knocking. Now, in order to take full advantage of those features requires tuning and possibly even tinkering like shaving the head, but I think there are some cars (probably older ones; eg a 1974 Ford 302 only made 98 hp -- that's less than a modern 2.5l 4 banger) that can use any/all the help they can get. So there is room for tinkering, but don't let an initial setback stop you; you should be able to get much more complete burns (I imagine a RX engine could really use this!), and a much higher detonation threshold (but I don't think it can prevent preignition from low-octane gas).

As far as water in the oil, all cars get it (most minivans are worse than cars even because for a while the valve covers were "cooled" by the cool airflow past the engine)... the solution to mayonnaise-oil is to drive the car more so that the oil temp gets hot enough to evaporate the water off. This is also a major problem in propane or CNG cars since the fuel is cooler and has less power than gasoline, but oil lasts longer in those cars because the combustion side products are much less nasty than gasoline.

So, while there's no free lunch (this won't make power from nothing), and it needs tinkering to take full advantage of it, it brings some unique benefits to the combustion table...it has a power when it's there....

As yrralguthrie said, adding hydrogen will not improve the mpg of a conventional-propellant internal combustion engine. They can make vehicles that rune solely on hydrogen, but that is a different matter, as they are engineered completely differently. By using incorrect fuel, you decrease efficiency, increase wear, and vastly increase the chances for catastrophic (and likely deadly) system failure.

On the issue of "green" energy, though it might be economical to the consumer, due to various subsidies, to use hydrogen as a fuel source instead of refined petroleum, the energy cost is greater. In any system, efficiency is less than 100%, so changing fuel (like oil, coal, or wood) to electricity using a turbine (losing energy in the form of heat and light), transmitting it over distance via power line (losing energy), using it to generate hydrogen and oxygen from water (losing energy to heat and imperfect systems), and finally using that in an internal combustion engine to drive mechanical motion or electrical potential (yet again losing energy) is a very poor way to do it.

To simplify that, all energy created by the hydrogen as fuel when it burns must have been put into the water in the first place to get hydrogen. Thus, it must by its very nature be inefficient.

This experiment demonstrates a scientific principle, and is a source of usable hydrogen gas, but do not pretend it has some mystical place as part of a vehicle not designed for such. That is pure foolishness.

I told you to read some physics. And actually I followed a friends activities very closely who did this, because I wanted to laugh at him. His mileage actually decreased. He used one of the systems sold on the internet. Big web site. Con. It is actually quite silly and uneducated to believe you can put something extra on a car and get more energy out of it than the car puts into it. If that were true we could make more energy than we consume and put some oil back in the ground.

What is truly silly is the assumption that "phsyics" is "known". "Knowing" completely cuts you off from anything and everything that contradicts what you believe you know. The "faith" of the "knower" renders contrary discoveries "fake" or "impossible" in their own mind.

That's why people who prefer exploration to belief and knowing and assumption are the ones who make all of the discoveries that are blown off, initially, until they become unignorable, at which point those who blew it off for years try to claim "I already knew that. That is old news.". That is why there are a lot more physics "fans" than there are Einsteins - a lot more "knowers" than explorers or discoverers. Society teaches faith and "fandom" so thoroughly that explorers are considered crazy renegades by their own generations. C'es la vie! It just leaves an explorer with more time to explore with less interruptions!

4 days ago

Actually there is a bit of difference between thinking there is more to learn and thinking that all we have learned is false. You profess to prefer exploration to belief and knowing and assumption. That is exactly how all those people, Einstein, Plank, Rutherford, Newton thought also. What we know today from these men is based on experimentation and exploration. Even today with the study of very small particles nothing is "proven" until one person does an experiment to show it and then several others do their experiments to show the same thing. You dismiss what you claim to believe.

One can't start with a false premise to prove a truth. You are just making stuff up and then trying to prove a truth. You in effect are one of the those knowers trying render the experiments of others as false. You are saying because you believe something will work all those people who came before you and preformed experiments and explorations are false. You would have been one of those trying to turn lead into gold. Or to fly by flapping a flat wing up and down. You are not a explorer, you are soothsayer. You base your beliefs on false or non-existent knowledge. If you want to say beliefs up to now are false then prove it. It is not the responsibility of believers to prove again what is already proven.

I know one thing you cannot prove that a hydrogen generator run by an alternator will increase mpg. You can think it all you want and you can botch up an exploration and say you proved it, but there will be flaws in your numbers.

4 days ago

I don't believe. I explore.

The beauty of exploration is that no premise is required. You see something new and interesting and you explore it and play with it and the other new things it reveals. There is none of that in turning lead into gold. What would be the point? There's no reason to explore beliefs. Not when when one is surrounded by such awesomeness. Things you can touch and see and play with.

There are things right beneath your feet that you would not believe and there is no one, anywhere, who has any obligation, whatsoever, to prove it to you.

Some of us explore things and that has nothing to do with what others are doing with their lives. It isn't up for a vote. It's not something that is decided democratically. We're already outcasts. Your approval of us is of no value, whatsoever. In a lifetime of DISapproval, we had no choice but to find a perspective that doesn't include such things. And as it turns out, the perspective of exploring without the "supervision" that comes from coveting approval from others is WAY more fun.

Turning lead to gold...pffft. Only one who fears disapproval wants gold. Gold is nothing.

This may be a viable way to produce one energy source from another however, as in any conversion, from one form of energy to another and using the newly converted energy to drive a spark ignition engine, there will always be significant losses along the chain of conversion and final use. If one is going to gather electrical energy from any renewable source (PV panels or wind turbines for example) then the best thing way to reduce energy loss is to store it in an accumulator then use that electrical energy is to power an electric vehicle.

A bigger alternator may work better. The only reason this isn't done now is you add friction and it will take more fuel to create the electricity. A generator would be much more efficient.

A lot of alternators (or just one really big alternator)would transform a lot of mechanical energy into electrical power, and induce a lot of drag on the engine. The increased drag on the engine would necessitate using more fuel, so you don't gain anything.

Dear Sir: This is nothing new! People have been trying to make a hydrogen fuel for at least (Last energy seminar I attended was 1979 @ Anaheim (CA) Convention Center)--at that time Hx fuel was \$8 bucks a gallon. (It was NOT availabe for sale either! The guy would start his engine and put a gas mask hooked to the exhaust pipe on his face. The engine allegedly put out water vapor (H20) and 02 gas. Nothing has been done in the 35 years that followed. In Germany however they have a "hydrogen highway" and BMW's that run on hydrogen fuel.

'nuff said. YOU can't do enough fuel to be financially viable and AND there is no infrastructure to support this product. Good luck. Hope the LORD blesses your efforts. Big Dan Bonewacker, city of Hespermia, CA 92345 U.S.A.

If you would separate the cathode and the anode (but maintain a fluid-connection of course), could you then collect the hydrogen separately from the oxygen? You can then use the oxygen in a bottle rocket (isopropanol driven) and the hydrogen in a balloon (with a fuse for a nice boom). For the bottle, I don't know if the mixture alcohol/oxygen would be too rich in oxygen, but better more oxygen then too little I'd think...?) In the case of the balloon, the oxygen in the air should do the trick too (cur. Hindenburg).

What do you think?

Great job, very well done.

I'm a fan of people just doing it and not procrastinating. Especially when it's a young lad. I've been building stuff my entire life and became very intrigued with Hydrogen generator's ever since Stan built the dune buggy. He had it nailed down pretty much and they not only took his plans they took his life. The technology for building hydrogen or hydroxy gen's is so much better today than then. You have a fantastic shot at making a buttoned down retail unit that works continually. Many have tried some have succeeded but getting consistent results is the trick.

In order to get everything in the system to remain the same or balanced would be a better word. Volt's amp's media, containers, volumes. When working with a vehicle such as a car and using the electrical system you have to use the right electronic components. I'm cheering you on and look forward to the next step in your evolution in this field. I have built a few and had success. I have never been able to pursue it uninterrupted by life and might just take up the challenge again after being inspired by your work. I'm semi-retired now and have more time to devote. I'm sure you have heard about the lads in Austrailia years ago who were running their daily drivers on hydrogen gen's and were threatened by the men in black. They had made successful units powering their old beaters and everyone wanted one in their community. Then all heck broke loose and they had to stop making them. We have exposure now they did not have. What I'm saying is there is less threat, and many many people have been making these generators powering any combustion engine known to man, pretty much. Keep working at it, perfect it, and make it yours. You have a good design with good materials that have lasting qualities. It's cutting edge tech and will make a global difference in these trying times. Thank you for sharing with us.

ferd_berfal4 days ago

Small correction, the statement "make a fuel that is much more powerful than gasoline" is incorrect. Gasoline, as it is used in an engine, is pretty much the highest energy density fuel there is. Gasoline, as used in an engine, has a higher energy content per pound than explosives or rocket fuel. (Diesel is a bit higher energy content that gas).

The secret is that for an explosive, or rocket fuel or hydrogen+oxygen you are carrying both the fuel and the oxidizer. For a gasoline engine you are only carrying the fuel, the oxidizer is free and isn't carried as part of the fuel (since the oxidizer is air). To burn one pound of hydrogen you need to carry 8 pounds of oxygen. It is generally more efficient to not actually carry the oxygen (even if it is pure) and to just use atmospheric oxygen.

They sell these systems to plumb into a cars carburettor to increase mileage per gallon. My question is do they gain anything as the battery has to be charged from the alternator which produces drag and lowers mpg?

I knew a guy who tried this in a 1999 model ford falcon (australia) He said it gave him 2-3 l better economy but he had to deal with the occasional mini explosion when starting. Start car, let warm up, start HHO, hope doesn't explode in face, drive. Also he didn't have the output adjustable so if you were idling it would produce more gas than needed and explode in the air box. If you adjusted to equal idle requirements it would produce too little to drive with reducing the benefit. Still 2-3l is better than nothing.

Im sure if some bright spark made a safer computer controlled unit that tapped into the ECU it would work.

4 days ago

You have a keen grasp of the obvious. You get less energy out than you put in. and, you will upset a system balanced for best mileage and lowest emissions. If your car is too rich or lean, adding a different fuel might make it run better (or worse); but tuning it or cleaning the injectors will be more effective.

A very nice demonstration of the hydrolysis of water. A very nice demonstration of the gullibility of people.

A gasoline powered internal combustion engine burns the gasoline in a controlled explosion which thru various lever arms is converted into useful motion: move a vehicle, pump water, compress a gas into a liquid, etc. This gasoline is produced in a process from raw petroleum, drawn from underground. It takes immense amounts of energy (electrical, more petro-chemical, even nuclear) to do this conversion. The BTU equivalent contained in a liter of gasoline is no way near the BTU equivalent needed to produce that liter of gasoline. The KM per Liter a car gets represents a very small fraction of the real energy expended in the production of that liter, it's transportation to your cars tank, the promotion of convincing you to BUY THAT liter , rather than another brand and the loss by evaporation.

The above demonstration of the production of water into hydrogen and oxygen, to be used in the production of useful motion/energy is nice to discuss, but not really worth it commercially.

Google "High Mileage Cars" or "High Efficiency Steam Engines" to learn about heat conservation, friction reduction, , steam/gas recycling, and thermodynamic theory.

kevshouse4 days ago

It pains me to jump into these discussions but I feel I must.

Although hydrogen may be perfectly usable as an energy storage medium in some circumstances.

The question that must be asked is whether or not a suitable hydrogen infrastructure can or can not be built that is safe, effective, affordable, and does not require a radical change to our lifestyle.

Before I continue I will point out that I fully accept that I our reliance on fossil fuels has to end soon if there is any chance of avoiding our own destruction. That is assuming we have not already passed the point of no return.

Getting back to those four criteria for a successful energy infrastructure we can see that those criteria are interrelated, e.g. there is no effectiveness without safety or affordability. Thus far I have never come across a scheme that describes a hydrogen infrastructure that comes close to meeting all four elements.

We could all try to do something similar to what this instructable suggests and build our own electrolyser, but we'd still need a large energy supply and some machine to liquefy the hydrogen (or store it in metal hydrides if we wanted to use it portably). The DIY, aspect, however, may break our safety criteria, and when one considers the efficiency of running an electrolyser (at best about 65%) combined with the efficiency of technologies such as solar PV (under 12%) we in fact end up with a combined figure of < 8% when and where the sun shines. This paltry sum is before we have even thought about storing any hydrogen and a long way before we get to use any. if we pretended that we can store it for free our best internal combustion engines are only 30% efficient so we'd end up with a 2.4% fuel efficiency - not great. If we go with fuel cells and electric motors we could expect about 4.8% fuel efficiency at cell output and 3.84% at motor output at very best! In favourable contrast the world's first practical engine ever built, a few miles from my home, in 1712 by Newcomen and Savery managed about 0.5%

We could possibly up those pessimistic forecasts if we used a wide portfolio of renewable sources, but frankly I doubt that enough of us have access to a wide enough variety of useable sources of wind, tide, geothermal, solar, etc. This I fear is the most worrying problem of all, there simply isn't enough renewable to go around (unless we are happy to go back to the global lifestyle habits of a century ago) regardless of how many wind/solar/tide farms we build.

Ten years ago the thought that I would write this would have amazed me, but the only technology that I think capable of leading us to climate safety is the much maligned atomic power station. If we take care we can neutralise its waste and ensure its safety and in return it won't destroy our environment.

For those that that doubt my reasoning (for others too) I suggest thoroughly reading David JC MacKay's excellent and entertaining book 'Without Hot Air' which can be downloaded for free via http://www.withouthotair.com/

So if I were to use salt outside would it be ok and not kill me?
ronald.cody.74 days ago

The one other thing most people miss. Hopefully even the folks the for some reason choose not to believe in science will understand. If you look on the periodic table that is the first element? Hydrogen right? It's the smallest atom so containing it is HARD. The other issue is simple contact with most metals under heat and pressure like in a IC engine will cause hydrogen embrittlement. This is not a good thing for your car.

The those who think you are getting more energy out this you can do a simple test. Just post an instructable of the following test.

Built a hydrogen generator that can run a small engine on it's own. Attached a DC generator to the motor that can run the hydrogen generator. It should run as long as you keep adding water the "power source" .This is NOT perpetual motion as per the theory water is a power source.

If you truly believe this system works this test should be a simple easy demonstration.

po941104 days ago

This is just like the electrolysis experiments we used to do in 1970's grade school science. It was cool then and it still is now.

But there are a number reasons Hydrogen produced this way, or Hydrogen at all will never become a practical alternative fuel for automobiles.

1. It has been determined that it takes 4-5 times as much electrical energy to produce the same amount of energy by the Hydrogen produced (Scientific American). Currently the most efficient way to create Hydrogen is currently from fossil fuels.

2. You would not want to carry around enough Hydrogen to get you anywhere. To get that much Hydrogen in your tank, it would have to be highly compressed, perhaps to the point of liquefaction. Hydrogen is the most volatile single element on earth. It would be like driving a Corvair around with the space shuttle tank attached. This is currently the biggest stumbling block in creating a hydrogen fueled car.

3. While Hydrogen is the most abundant element on earth, most of it is bound up in seawater. Hydrolysis with seawater creates some nasty pollutants like chlorine gas, hydrochloric acid, and hydrogen sulfide. Seawater would have to be desalinated first.

4. Potable water is starting to become scare. In some places fossil fuels are more readily available than water.

"This breaks the laws of physics! You can't get more energy out than you put in!" OK, geniuses, I mean tools of the oil industry, you have to keep putting water in........... Please explain how this is creating energy out of nothing. If this were a "perpetual motion machine", you'd have to put water in once and then like magic the system would run forever. That's not what anyone is claiming. Hmmm. Just like big pharma is behind the war on drugs, big oil is the reason hydrogen powered cars aren't commonplace. It ain't rocket science, it's money and big business.

and there is no toxic fumes, associated with sodium or potassium hydroxide. even though the solution, itself remains toxic. the hydroxides remain in solution, as hydroxides unless you are using contaminated hydroxides.

i make potassium chlorate, and perchlorates using potassium chloride as an electrolyte. and will get the same result using, sodium chloride salt.

and chlorine and hypochlorite's, are made by using the electrolysis of sea water.

maybe you shld think before you speak as well :-) if you use Sodium Chloride ( 'salt') the result will be chlorine gas due to competing half reactions :

2 NaCl + 2 H2O → 2 NaOH + H2 + Cl

2 H2O → 2 H2 + O2;
by the way, the NREL
estimated that 1 kg of hydrogen (roughly equivalent to 3 kg, or 4 L, of
petroleum in energy terms) could be produced by wind powered
electrolysis for between \$5.55 in the near term and \$2.27 in the long
term

4 days ago

yes but you left out the intermediate reactions, involving sodium and dissolved chlorine prior to producing sodium hydroxide.

i worked for the predecessor of NREL when it was called SERI, as a jr scientist. and you are correct on the energy output, of hydrogen vs fossil fuels. as you go up the hydrocarbon chain, the greater is the discrepancy. the octane rating, will make a difference in the ratio. a mixture with more hexane, heptane, octane, will be more energy than with more nonane, decane and unodecane. and even a greater discrepancy, for diesel.

but i am, surprised they have brought the cost of production down that much with wind generation.

1 month ago

Since distilled water is purified and does not
contain any impurities, it is unable to conduct electricity. Water
molecules on their own have no charge and as a result they cannot swap
electrons. Without the swapping of electrons, electricity is unable to
travel through distilled water.

The apparatus generates hydrogen. Though it can be used as a fuel in internal combustion engines, that is inefficient. However, as noted above, hydrogen has other uses as fuel where electricity would not work,prominently high-temperature torches and welding, but also rocket fuel in some instances. Most other uses of hydrogen are in manufacturing and pure science.

4 days ago
also, the statement that burning hydrogen produces more energy than gasoline is just wrong.

you can verify by looking up the energy densities, but it's also common sense. a hydrocarbon is a chain of many hydrogen atoms that can be oxidized, which is why it's used so much.
4 days ago

two molecules of hydrogen, with one molecule of oxygen shall always produce the same amount of heat output. but when hydrogen is coupled with carbon, the redox involved breaking the carbon chain apart consumes a small amount of the energy. and producing carbon monoxide, is also less efficient than producing carbon dioxide. then you have the problems of the oxides of nitrogen, added to the process which also detracts from the efficiency.

so one pound of hydrogen, is not the equivalent of one pound of fossil fuel. the one pound of hydrogen, will always have a greater heat output than one pound of fossil fuel. with CH3 being, the next closest equivalent.

do not! use salt, NaCl produces chlorine gas instead of oxygen. and depending upon the energy input, will produce sodium hypochlorite, sodium chlorate, or sodium perchlorate.

Cool project, but the biggest problem with Hydrogen is storage. It is the smallest of the Molecules and is very hard to store. I would also be concerned with having Hydrogen and Oxygen in proximity, they get to each other and you get a big boom.

4 days ago

Not sure about this particular apparatus, but with an on-board converter, the hydrogen is perfectly "stored" in the water. There is no "storing of hydrogen". It is spent as it is released.

"Storing" hydrogen is about making money - not energy.

hydrogen, can be safely liquefied though it takes more energy, to compress it to a liquid. not sure it would be feasible, to add the cost to liquefy the oxygen. for the slight amount of power increase over using air.

Well now the King of Random also has weighed in on this issue, and yet the naysayers who have NEVER TRIED IT, but stick to applying the theories they think are at play into the equation and call it nonsense.

So King of random, despite showing this fuel burning, there is some magical way in which, when its put under the hood of a car, the engine knows its there and decides change the laws of physcis and not burn it.

Naysayer's basing their *opinions* on an incomplete concept of the process under the hood only think they have the complete picture. When a system is built and seen to work (nowadays have to fool the O2 sensor in the car though), it is only then the facts comes to light that this is not energy creation like naysayers think it is.

The HHO system is simply utilizing a chemical advantage as a "lever" to make fuel burn more efficiently. Lighting a stick of dynamite also releases a lot more energy than it took to strike the match - but it does not create energy from nothing. The heat and flame release the potential energy inherent in the chemical properties of the TNT. Burning HHO made from a car battery does not create energy - it uses the chemical advantage of the gases being highly flammable to improve burn efficieny.

I am not affiliated with the following ebayer - but he has close to 4000 satisfied customers who also have a forum - who utilize this type of system to imporve gas mileage:

I personally appreciate this, and I may well have most of this laying around in scrap SOMEWHERE............

And a question; is it possible with a few mods to collect the O2 separately? (Before anyone screams "Bill, you missed it! it is Just O!" No, it isn't H,N,O, and a few others are di-atomic; taking 2 of the atoms to comprise the actual element. The likelihood of a free radical simply continuing to exist after this is close to zero.)

some of you assume it is pressurized .you use it as it is being made and using the suction of the engine would put the system in a vacuum . you don't need all the expensive equipment. you need only 12 to 15 volts to generate the mix you need. just place a volume control knob in line to adjust the volts. the mix of electrolytes will change on it's own as the mix becomes concentrated . just add water to thin it back out and you get the right mix and volts. the system you need is no bigger than what he made. why do people make it complicated. the heater fan in most cars use 15 + volts does it not? you can put a propelar driven generator on the car so it only makes gas while moving. and the prop stops no gas . many ways to solve the issue and not have to build factories to buil something you don't need to build.

Someone mentioned electric cars won't last. So far they have lasted the longest of any cars. The original electric cars were powered by nickel iron batteries, something that many of us yearn for if we build solar electric systems for our homes. Still waiting for a more economical way to produce hydrogen gas, transport it, store it. There is some promise there but more development is required.

Makedo4 days ago

when you use the gas produced it makes the type fuel in your car burn better. it is the way hydrogen works. so your making a hybrid out of your car. no you do not want to just run this mix because you will not get the power you need by it self. gasoline with this mix will completely burn and you will get water coming out the pipe. and you can do this because it has been done. a chevy silverado got 65 miles to gallon when not loaded and yes under load it is less. yet still over 20 mpg when pulling a trailer. (30ft boat) try that with a prius.

@mjbedford stainless is the best material, since using platinum or gold will not make the profit any bigger, pure iron or pure steel would be better though but it would just rust in seconds attached to 24 V's. to check it just check elektrolysis on wikipedia there u'll find proof to it.

@dan.blake.7583 btw this is not browns gas, as simple as that, and it does not matter wether u use destiled or normal water. actually normal water would be better, if u would not care about a clean tube, since more minerals in the water will make it easier for it to transport the currency.

kilroy_504 days ago

Unfortunately, the energy input to electrolyze water is greater than the energy that is obtained by burning the resultant hydrogen. That's just insurmountable with current technology with the possibility that using solar or geothermal energy _could_ break that barrier.

Secondly (and probably most important concerning this type of electrolyzer), the gas generated herein is the mixture of Hydrogen and Oxygen with the proportions of two parts Hydrogen to one part Oxygen and that particular ratio of H to O is extremely explosive. A single, small spark is all that is necessary to set it off. A large quantity of the generated gas would produce a large explosion. Look up Hindenburg disaster to see what a Hydrogen explosion can do.

On a side note, the mix produced here is also known as "Brown's Gas". It (*is*) a handy fuel for some types of engines but put it in your car or motorcycle and you will probably create a very large piece of lawn art.

Anyway, it's a good instructible so be careful and have fun.

BTW, common table salt, as mentioned in the 'ible, is not quite as dangerous to handle as is the lye.

It would be amazing if you had a generator that would provide most or all of your energy as hydrogen is hard to store. If you did have a source of hydrogen the losses from compression would steal a lot of your stored energy. But wait there is a technology that can provide all your energy or at least most of it and is a lot less complicated. http://www.dailymail.co.uk/sciencetech/article-2767806/Meet-Stella-solar-powered-car-drives-500-miles-SINGLE-charge-warns-traffic-lights-change.html This vehicle driven under 150 miles a day could provide very inexpensive transportation.

I wanted to point out 3 facts:
1. If you are going to make this, you should research better metals for the plates. Stainless is cheaper and easier to obtain but not the best choice. When used in electrolysis, the metal will also release compunds from the metal such as Chromium which makes the water toxic.

2. Dome areas of the country are in a severe drought!

3. People that use forums and comments to argue and bash each other ruin the essence of forums and comments. Makes me sick. We should all be able to add our comments without getting attacked. It is frustrating when i am trying to get everyones opinion and i have to sort through this garbage. It doesnt make you look smarter than the person you are bashing FYI.

Fantastic Instructable, thank you. I have been reading about this sort of hydrogen/oxygen splitter for years. I was at first intrigued by the claims of some to be able to run a car on this technology. Ok, that was soon pretty well disproven despite some clinging to the myth... Maybe now is the time that the myth can be revisited and possibly becoming proof finally? I say this because solar photovoltaic panels are now much more efficient. Maybe these higher quality and cheaper panels could be used say on the roof of a car or other vehicle. It does not then matter that the energy you get out is less (which I fully accept) as it is still free. As you say this is 'converted energy'. Gas is easier to use to propel a vehicle than solar PV produced electricity. Perhaps a hybrid vehicle to start with? Just some thoughts of mine :)

The gas produced by the generator can be used in a water heater?

Stroover7 months ago

I'm wondering the same thing abrown39 and krash are. My fragmented mind is telling me that if the middle plates are just kind of floating there unconnected that they wouldn't produce any gas without currant flowing through them.

3 months ago

No it's not like that at all. Even I was a bit puzzled in the beginning but now it makes sense:
The plates are in pairs - sort of like how capacitors are but instead of having 8 pairs of plates connected in series, it has 2 sets of 4 pairs each. Essentially it's like having 1 set of 4 pairs of plates with twice the surface area. from the "terminal" in the middle, the current splits in 2. The one which goes right is pretty straightforward. the one which goes left, goes to the last plate, then goes through the U-bracket to join in the last plate at the terminal.

hope it helps.

5 months ago

Perhaps they're connected through the electrolyte.

7 months ago

The whole point is that the gap between the plates causes the electricity to jump the gap between the two plates by traveling through the water. When the electricity does this is ionizes the water into 2H+ and O-. Once two of the water molecules have been ionized the Ions then combine to make H2 gas and O2 gas which are more stable than the separated ions.

That way, you are radiating (wasting) more of the energy (heat) to the air. Basically, a boiling water in electrolysis generator is very inefficient process concerning energy to splitting ratio.

To prevent too much heating, increase the face area of the electrodes and decrease the amount of electrolytes in the solution. That way, the current needed in the system is decreased.

Is there a reason you are using stainless steel plates as opposed to aluminum? While both are resistant to oxidation I would think aluminum would be better as it is going to remain submerged in the water.

7 months ago
I'm not an engineer of any sort, but I was experimenting myself with different materials, aluminum included. The process is technically and electrolysis.aluminum seemed to me to transfer electrolize easier or more readily than stainless steel did. Electrolysis literally removes an atom from one plate and places it on the surface of the next plate. I tried combinations of different plates, as in using aluminum on the cathode and stainless on the anode, vice versa. Also lead and copper we're tried. Stainless seemed to be the most stable.

The process generates heat, and all metals will distort to some degree from heat. Stainless seemed to be rather stable in this as well.one thing to consider, because of the close proximity of plates is too maybe use an intrinsic insulator between the plates. This obviously needs to be porous, and the best thing I have found is, oddly as it sounds, tulle from the fabric and sewing stores. the thicker the plate, the more stable it will be also.

I'll also comment on oxidation. Aluminum itself is very reactive and does oxidize quite readily. Life experience and work as a welder and show me this. consider a roll of aluminum foil in the kitchen. As you roll it out you will notice a thin charcoal grey film. That is oxidation well simply sitting in the box not in the water. Stainless does not develop this as rapidly.it was called stainless steel for a reason, it is not as reactive.

one more thing to consider is that acidity is measured by counting free hydrogen.the more free hydrogen available in an environment the more acidic it is. Aluminum is highly reactive to acid.

Hi there,
Thanks for this great tutorial!
I have one question. You talk about the voltage applied to the system but you didn't refer the total current drain. Did you measured it? I think that although the voltage is an important parameter, the current is a more relevant one.

If you're having a high current passing over the system, this means that you are transmitting more energy than the system really needs to an efficient electrolysis and that drives you to extreme heating and thus, energy loss by heat.
I'm taking in serious consideration the built of a generator like yours.
Your answer will help me determine if i'll do it like you or with a different design.

just a few shot in the dark questions, wouldn't magnets help seperate the particles since they are ionic in nature. but regardless of that, storing the gas would be a terrible idea enough said on that. secondly would changing the plates into two cork screw shapes one inside the other both of them without touching each other help in the conversion process? thirdly could the geet system be used with the hho generator? also how about recapturing the released water? consider if u buy ten gallons of water and just keep reusing it wouldn't the cost eventually be a profit? also some other curious thoughts to ponder. the capacitor idea, can it be charged using solar power. then u could use the entire surface to directly charge the capacitor during the day. also some other thoughts, what about using that sterling motor to help the performance? ideally set it in the exhaust system and use it to help generate electical energy. or how about a turbine in the exhaust system to help recapture some of that energy since it is free energy.there are a few other questions to be had mind u. for instance what about a few wind turbines integrated in the car to help collect more free energy? also does the water come out hot after it has been rebonded? and is there anyway to tie this back into your power grid at home , i.e. i would love to flip my electrical meter back and have my power company pay me for producing energy. see i have this idea of using solar panels with this HHO generator to produce energy during the day and at night turn it off. so any energy i dont use just gets plugged back into the power grid and flips my meter.

though the water is a renewable resource, the iron/steel used is an oxidizing metal, meaning it will eventually rust to nothing. using other similar superconductors like copper will result in the same.

Have you considered using a Pulse Width Modulated power source as opposed to a car battery? Supposedly the heat you got in your 24v test is a result of inefficiencies and too much current being turned to heat instead of gas. PWM allows the water to stay cooler with higher voltages by pulsing the voltage instead of a continuous flow. It's worth a shot.

Water is made of 2 hydrogen atoms and one oxygen atom. Thus, it is known as H2O. When you apply an electric current, it splits it into 2 hydrogen atoms and 1 oxygen atom. This creates the gas you see.

apparently.... "Stainless steel contains chromium and thus the chromium is consumed, and you end up with poisonous chromates in your electrolyte. Dumping these on the ground or down the drain is illegal. The compounds can cause severe skin problems and ultimately, cancer. Hexavalent chromate is poisonous.
Does your electrolyte turn yellow? That's a sign of chromates.

This looks like a really awesome Instructable, I can't wait to make my own. My only problem is that I can't really obtain any potassium hydroxide, and I don't know where I could. Can anyone point me to another catalyst that works, or where to obtain potassium hydroxide? Thanks,
