How an HHO generator works and helps you save gas

An HHO or Brown gas generator is an interesting and often misunderstood technology.
The Brown gas generator uses electrolysis to split water (H2O) into it´s base molecules, 2 hydrogen and 1 oxygen molecule.
This is why it is often referred to as an HHO gas generator.The HHO in itself is not an alternative to gasoline but a additive
to boost the efficiency of the engine. Gasoline engines are unfortunately not burning gasoline to its full potential. See
The average gasoline engine in a car is about 18% to 20% efficient. That leaves a lot of room for improvement and Brown gas is one good way of improving the efficiency. The reason for this is simple, the hydrogen is highly flammable much more so than gasoline so when your engine ignites the hydrogen the explosion ignites the gasoline with much better results (cleaner, less waste and fewer emissions) than it would otherwise have done.

Some basics the burn speed of hydrogen is 0.098 to 0.197 ft/min (3 to 6 cm/min) compared
gasoline´s 0.00656 to 0.0295 ft/min (0.2 to 0.9 cm/min).

The hydrogen explosion is so fast that it fills the combustion cylinder at least 3 times faster then the gasoline explosion and subsequent ignites the gasoline from all directions  (it is like putting flue on a fire), instead of just a spark in one end of the combustion cylinder, and we would like to do that because the gasoline only has a short time in the combustion cylinder and if its not fully burnt in that short amount of time then it just goes out the exhaust and is lost.It is also preferable to ignite all of the gasoline when it is under maximum compression in combustion cylinder to get the maximum amount of energy out of it (this is a small time window),whonce the piston starts going down the energy transfer from the explosion to the engine becomes less efficient.

The hydrogen´s higher burn temperature and explosive force is such that it cleans the soot that collects in the engine (it is like having the engine consistent maintains) and with a cleaner engine you get better mileage and fewer oil changes .

Step 1: Tools and Main Components

Picture of Tools and Main Components


Glue gun
Drill and bits
Metal saw
Soldering iron
wire crimp
wire cutters


HHO Generator
Pulse width modulator (PWM)
Electronic Fuel Injection Enhancer (EFIE)
Electric wires
Air connector
On/Off switch
Cable connectors
One way air valve
Piece of sheet metal
Peace of rubber

Step 2: The Brown Generator

Picture of The Brown Generator

I modified the Brown generator I bought on ebay by adding connections to the places and replacing the spacers with smaller ones to increase the surface area.
You will have to buy bottled water because tap water can have  metal in it that will rust the plates.
You will also have to ad an electrolyte to the water  to speed up the electrolysis.
The highest production of  hydrogen occurs with the plate polarity alternate as in +-+-+.( It also consumes the most amount of electricity)

Step 3: Pulse Width Modulator

Picture of Pulse Width Modulator

Is an important tool to control the electrolysis. A simple generator can be built without PWM but that is like having an engine with only the possibility of full throttle or no throttle at all. The pulse width modulator is necessary for a controlled electrolysis. The specific frequency and power for the most efficient electrolysis wares form generator to generator.
You will have to fine tune the PWM your self but that is simple. You just fine tune the frequency first, by tuning the frequency up until the bubbles from the electrolysis plates start decreasing after you hit maximum bubbles and then go back to the best setting (producing the most
amount of bubbles) and then do the same for the power setting. It is best to get a powerful PWM at least 35 Amps preferably more.

I use a 50 Amp PWM and a LCD Display from canakit.

Step 4: EFIE

EFIE (Electronic Fuel Injection Enhancer)

The EFIE is intercepting signals from the oxygen sensor to the computer and fools the computer by giving it false exhaust readings from the Oxygen sensor.This is necessary because the computer is set up for a regular burn of fuel and compensates for the more efficient and cleaner burn by dumping more gasoline into the engine (until it gets the reading it expects) which ruins your fuel savings.
Gasoline burns better (cleaner less waste) with HHO gas because the increase burn temperature .

You can buy a EFIE on the internet or if you have the skills you can build one.

Step 5: Installation

Picture of Installation

I made a hole for the wires from the PWM to the Brown generator along side the existing electric cables,
the I put a peace of metal (with rubber on one side) around the Brown generator and screwed it to the frame of the car.
I drilled a hole in the air intake behind the air filter and inserted the air connector. I then put one way air valve on the hose
and connected the Brown generator to the engine.

Then I lengthen the cables of the PWM, thunk the variable resistors out and attached them til long wires, I also mad an manual on-off
switch  extension. I then used the glue gun to glue the PWM  to the top of the small glove box under my steering while,connected the wires slid the glove box into place  and then glued the variable resistors and the LCD Display in the small hatch where the fuses are.
It is all easily accessible bot not visible.

I'm pretty sure the additional electricity your alternator has to provide to generate the hydrogen outweighs the additional efficiency provided (a.k.a. perpetual motion). Throw some large solar panels on the top of your car/truck to power the HHO generator exclusively and then you might have something.

lucek (author)DarkStarPDX2011-08-05

Yeah he's got a rather poorly designed pseudo electric car. Forget the fact that even with a pretty good energy source thees devices can't produce that much gas/minute. producing the same amount of force from thees it take 3 times the mass of water then gasoline. You rarely see one of thees devices with more than a few gallons of water. And again is you have the perfect device at the theoretical best efficiency 94% (best devices ever made are in the range of 70%, I've not tested this device but a device in a lab under perfect conditions are working at 70% this ain't even close.)

JayY2 (author)lucek2017-09-01

These are fuel SUPPLEMENTAL systems, NOT fuel replacement systems. You can run a vehicle off straight hydrogen, but that is not what these on-demand systems are for. They are merely for causing the fuel you pump into the tank to burn more efficiently. They are NOT perpetual and NOT classified as perpetual. I don't know where that came from: Probably from Big Oil companies trying to kill it.

JayC97 (author)JayY22017-09-09

No it doesn't. Every single time these are tested by people who aren't invested in HHO they don't work.

Again it doesn't matter if it's supplement or replacement or catalyst (which it isn't even close) conservation of energy comes to play. Any energy generated by the burning of the brown gas can only I repeat can only produce at most the energy used to split the water. That's with 100% efficiency in every part of the system. Best case scenario in make believe world this adds nothing to the system but extra weight. Even that is crazy however as getting 10% efficiency total is a pipe dream.

lapsik (author)lucek2015-07-06

For every gallon of water you can get 4707 litres of H2, thats at atmospheric pressure and freezing point. So, it would seem on the face of it that H2 production by electrolysis is worthwhile. I agree the main problem is producing enough to properly suppliment your current fuel, but this talk of inefficiencies and costing more to produce than it delivers is hogwash. The weight of an H2 generator is under 10kg fully loaded. The H2 generated will improve combustion, reduce emmissions and should save money long term. Thats 3 positive benefits. "There are none so blind as those who will not see"

PierreM33 (author)lapsik2016-04-14

On an enegy level, there is no difference, no improvement.. but on the COST side, yes there could be a lot on money saved.. water cost a lot less then gasoline (unless you drink Perrier) but tap water in here is cheap, real cheap and if it can help some fuel.. that is where someone will save.. But not on the energy ratio created.

lucek (author)PierreM332016-04-14

If the electrolysis of the water and combustion of the brown gas were 100% efficient (which physics tells us they aren't) there would be no net increase in energy produced by the engine. So no burning brown gas produced by electrolysis is more costly. IE it is infinitely more costly. You are wasting money to do nothing. But as said above that is if the system is 100% efficient, it only get's worse when we start talking about 30% efficient engines and 40% efficient alternators and a electrolysis device with no known measure.

lucek (author)lapsik2015-07-19

Flat out no it doesn't. Messing with the O2 sensor changes compression increases pollution and damages the vehicle. Adding the trickle of brown gas does just about nothing either way. Don't trust me. Look up tests where the system is turned on and off without messing with the O2 censor. Hell do it yourself. Efficiency increases when the brown gas generator is off.

lapsik (author)lucek2015-07-19

3 ways to easily bypass the O2 sensors, remove them, remove the cat(s or fool the ecu into thinking your not running too lean. If you take off the cat(s) you gain a much free'r flowing exhaust. If you then are able to produce sufficient hydrogen to effect efficient combustion then you will have a cleaner burning more efficient SI/CI engine. Just bypassing or removing the O2 sensors wont have a detrimental effect on the engine, it will have a detrimental effect on the cat(s), so best to remove them.

lloydrmc (author)lucek2012-04-01

That's the spirit!

Actually, modern day alternators are designed in such a way with such thick windings that the average auto owner will never use more than 50% or 60% of the what the alternator is capable of producing. That includes when you have all your lights on and every accessory in the vehicle going simultaneously. Auto makers have put over sized alternators in their vehicles(at least the domestics) since the mid to late 80s. Which consequently is about when they started EFI (Electronic Fuel Injection) as a standard, which an HHO application would require to have any effect anyway. The alternators used in modern vehicle's use electro magnets and voltage regulators in order to be able to restrain the alternators way back as to not over charge the system. Your HHO generator would have to be putting quite a draw to really have much, if any, effect on your engine or fuel consumption.

Long and short, your analysis isn't INCORRECT entirely. There are clearly some variables to be considered in each case. However your line of thinking is more in line with the generators they used to put in vehicles in the 60s and earlier, which had permanent magnets and were affected by every extra voltage draw as opposed to the alternators of today with electro magnets.

Please excuse my rant, I'm by far no chemical expert, I'm just starting my research on HHO generators in automotive applications. I do however know cars and quite a bit about generators and building them, so I just wanted to throw my 2-cents in. Thanks, this rant was fun!

Jurie-W (author)rattlesnake289772016-02-28

I do however know cars and quite a bit about generators and building
them, so I just wanted to throw my 2-cents in. Thanks, this rant was
fun! ........To control voltage and current output of all car generators and alternators, the current flow through the field/rotor electro magnate is altered. No permanent magnets is/was used. Some residual magnetism of the generator field coil core is there to start a generator working [They must be polarized correctly]

A medium sized vehicle will use 1 liter more fuel in an 8 hour day driving with lights on on a smooth level surface at 60 mph with no wind blowing.....Think how much this system will waste.....Better just feed some water to the intake when the engine is hot and stop adding water 30 minutes before the engine is stopped. As very old motor mechanic and motor- teacher I advise that you stop wasting your time on this brown gas system.

JayY2 (author)Jurie-W2017-09-01

You, sir, are thinking of the old car generators that become hard to turn the more they are asked to supply. Modern alternators don't do that. The need the same amount of energy to turn when outputting 10 amps as they do when outputting 100 amps. They are by far more efficient than the old generators that the output is proportional to RPM. I have been working on automobiles for over 40 years. These supplemental systems do work with modern alternators, but not with old generators.

JayY2 (author)rattlesnake289772017-09-01

HHO generators are efficient on carburated engines, also, you just have to manual tune to where it runs good at a certain point (idling down, timing), and then go. It just won't make the variable adjustments as you drive as with EFI. It's not quite as efficient, but it's the difference always inherent between carburated and EFI.

Darkstar is correct, even though an alternator is capable of producing more than what the vehicle needs to run the electronics. It is only generating what is required. There isn't 100 amps of current being generated and simply waiting to get used. As you increase energy demands the magnetic field inside the alternator gets stronger, the engine uses more fuel to overcome the stronger field and in return outputs more energy to meet the demands of the system. The question at hand is, if you have a system that is running at 30A and you add an hho generator that wants and additional 10A. How much more fuel do you have to burn to overcome the additonal load? And how does that compare to the efficiency the hho adds to the combustion process?

Jurie-W (author)buck.brown.102016-02-28

Seems to me that no one knows how alternators work! An alternator deliver only what is asked by the complete electrical system.

mracksmith (author)DarkStarPDX2017-02-01

Hi, I know that perpetual motion at this particular period of time is not possible, personally I believe it will be a reality one day but that's another topic. The thing that concerns me a little is the amperage required. I have heard numbers like 29 amps. That is considerable, the question is what will those additional amps require? Well, it will make it harder to turn the altenator, there by requiring more power in order to spin it, robbing the engine of some of it's, HP. But that's (as far as I can see) not really the question here. What I mean is that if we look at the current in vs the hydrogen out, I would agree that there is little doubt that the amperage would out weigh the hydrogen produced, hence illustrating that it is not perpetual motion. But I think we should also remember that 1, apparently the hydrogen enhances the burn of the fuel by virtu of it's higher and more complete burn scenerio. Apparently, and I didn't relize this until recently the efficiency of the typical internal cumbustion engine is not that high, again I have heard (second hand) that it is around 30%. That kind of surprises me. I am going to inquire about that. Anyway not only does the hydrogen burn hotter, it also burns faster and this apparently aids in ignighting almost if not all of the gas o2 mixture. So if we can reduce the amount of gas because of the increased efficiency then I could see how less fuel would be required, if we adjust the o2 sensor to permit the difference in efficiency, I guess we can do that? Let's not forget that the hydrogen is also going to expand thereby helping to increase the compression as well. The altenator is part of a closed system that puts out more electricty than what is needed, yes it will increase the resistance to spin the altenator but to the point where we loose enough hp to increase the fuel consumption to the point of burning more fuel that without the HHO generator? I think not but I'm not sure. I would guess no though. I mean, I think our present set up with internal combustion is far from perfect and I'm sure we have all heard the stories about carberator's that have been deveoped in the past with far greater efficiency than anything we have ever seen but the blue prints have been bought and shelved by those of us who benefit from the volume of fuel burned. If not I have heard stories of that nature going back decades. All I'm saying is that I do believe it is possible to increase the level of efficiency, especially if what I have heard is true and it's only 30%. I hope it's true!

JayY2 (author)mracksmith2017-09-01

HHO generation is not perpetual motion. You must have an outside source to use it each time. The system is a system enhancement. Just like burning gasoline in engines are not perpetual, neither is using Hydrogen perpetual. In order for it to be perpetual, it would have to draw it's fuel source from thin air, instead of having to add anything as a fuel source.

JayY2 (author)DarkStarPDX2017-09-01

Unless you already have a faulty alternator if will not reduce engine efficiency. No matter the output of an alternator, it does NOT cause more drag on the system. It either has a drag for charging, or it doesn't. There will not be more drag if more amps are used. And an HHO system is NOT wired straight to an alternator, anyway, it goes through the battery which acts as a regulator it's self.

GioV1 (author)DarkStarPDX2015-10-23

You couldn't be more wrong. There is a lot of unused power generated by the alternator that simply gets sent to ground once 14.4v is achieved with the use of a properly tuned system one can make use of the otherwise "waste energy" for hho creation. Additional power will be created by the more complete burn of the already existing fuel in the combustion chamber. The use of a pwm (pulse with modulator) is ideal for such tuning. EFIE is used to resist the signal coming from the oxygen sensor. The oxygen sensor sees the additional oxygen (the "o" in your hho) and reacts by asking for more fuel.

imaging (author)GioV12016-07-08

There is no unused power. The alternator is instructed by the voltage regulator (which may be built into the computer) to produce only as much power as is needed.

mracksmith (author)imaging2017-02-01

Yes, but that doesn't mean the altenator is functioning at it's max capacity, right?

JohnR620 (author)GioV12017-01-06

I know Ford. The 'oxygen' sensors are in the exhaust manifolds just forward and aft of the catalytic coverters. Since, the brown gas is stocichiometric due to process, there should be no increase in oxygen at exhaust. I would theorize that there would be a reduction of oxygen sensed if the gasoline combustion is 'more' complete. Perhaps the reference is to the mass-air flow sensor which is at the air intake? Then I could see that indroducing more oxygen in the air intake system would have an effect, if there were oxygen sensors in the mass-air flow sensor, which I believe there is no oxygen sensers in the intake system. The only oxygen sensors I know of are in the exhaust system.

JohnR620 (author)JohnR6202017-01-06

Okay - after looking at the description of "EFIE" function, I assume that an EFIE is added when oxygen is added such as when injecting Nitrous Oxide.

With HHO there should be no increase in oxygen. Could the EIFE also be used to compensate for the decrease of remaining oxygen in the exhaust?

rinksrides (author)GioV12016-07-04

huh?! Modern Alternators have 90A+ capability, PWM based regulators and a steady regulated output voltage of 13.8V. A correctly functioning alternator will have 0A output at 0A load. You should upgrade/replace your alternator if it operates as you describe. Also if this system causes the ENGINE to run lean then you run int detonation, worst case = spun rod bearings or melted pistons.

PierreM33 (author)GioV12016-04-14

there is not waste energy, there is more energy potential. And alternator or gererator use mecanical energy to make electrical energy, the more power you ask at the generetor, the more mecanical energy it need to make it. Think of a small dynamo you had on your bike. When the light where off the dynamo was easy to turn and all was well, not turn the light on, and you had to work a lot harder to acheive the same speed..

lucek (author)PierreM332016-04-14

You may want to check your theromodynamics again. Every system has waste energy. And as the only energy source is the gassoline that's a problem.

Jurie-W (author)GioV12016-02-28

Gio, Please learn how an alternator works as it charges the battery.

A lot of energy goes to waste when the alternator change the engines mechanical energy to electrical energy [used for electrolysis] and no electricity is grounded when the battery is fully charged.

Luis-Mario (author)DarkStarPDX2016-12-08

No one is saying this is a perpetual motion something for nothing. Hydrogen gas is cheaper than gasoline if you make it yourself, like a home-made apple pie is less expensive than a commercial one.

mayur.phadte (author)DarkStarPDX2012-03-02

So u say that electrolysis of water takes up more energy than hydrogen explosions?
Hydrogen burning=Chemical energy harvested
Hydrogen separating=bonding energy destroyed
I know u are applying conservation of energy.
But the energy liberated after burning H was not the energy provided by electrolysis.It is chemical energy,it was already there.

squiggy2 (author)mayur.phadte2012-03-12

Bond energy IS chemical energy. Breaking the bonds in water molecules requires exactly the same amount as is released when those same bonds form in an explosion. wikipedia enthalpy if you would like to know more.
The problem is though, that alternators are not 100% efficient, and nor is the electrolysis process, due to electrical resistance. Therefore, it takes more energy to split the water you get back from the combustion.
To my understanding, correct me if I'm wrong, but using HHO as a fuel additive isn't as simple as getting only as much energy as the HHO provides, but I think it actually improves the efficiency of the petrol combustion, so you would end up getting more out of your engine despite working the alternator extra hard.
Can someone confirm this?

mayur.phadte (author)squiggy22012-03-14

During electrolysis,H20 separates,so molecular bonds are broken.
during HYRDROGEN explosion,I don't know the actual REACTION EQUATION.So I maybe wrong there.But understanding the amount of energy evolved in a hydrogen gas explosion I don't really think it is supplied by the battery.

Jurie-W (author)mayur.phadte2016-02-28

Petrol consists of many different chains of molecules which ignite at different temperatures thus is burn very fast but it does not explode! If your engine detonates, you hear a pinking sound [part of the fuel mixture explodes]. This is bad for the engine.

squiggy2 (author)mayur.phadte2012-03-14

Sorry I didn't really understand your response, but am I right in thinking you meant to say:
"Electrolysis supplies energy to breaks molecular bonds. Hydrogen gas explosions release a lot of energy, which was not originally put in by the battery".
If that's what you meant, then this is my reply:

The equation for electrolysis of water is as follows
2H2O + energy => 2H2 + O2

The equation for combustion of hydrogen is thus
2H2 + O2 => 2H2O + energy

It's the exact reverse. Hydrolysis is just a backwards explosion.
If you don't believe me there, here's something to ponder...

The first law of thermodynamics states that "energy can be neither created nor destroyed"
This means that the total energy of the system, in all its forms, must be equal both before and after a reaction. So...
If the system has x amount of energy, provided by the battery to electrolyse the water, where does the extra energy come from which is released by the hydrogen explosion?
The energy has to be in there originally, to be released, so according to your explanation, if you electrolyse water, then combust the hydrogen, electrolyse that same water and repeat 100 times, then the hydrogen would eventually run out of energy because electrolysis doesn't put back in as much as combustion releases...

mayur.phadte (author)squiggy22012-03-14

All you say is right,provided the explosion reaction reaction of hydrogen is the same as you have written.I don't know,though that's logically right(the reaction).
So,yes if thats right then the combustion helps in the fuel burning properly.
:P Thanks :P

AjitM1 (author)squiggy22015-09-12

Yes... I have tried a locally made fuel saving device which produces HHO, has given me an additional mileage of 30% in city and more than 50% on long drive in my 2 wheeler. I am from Mumbai, India.

BungotT (author)AjitM12016-01-04

can you share your schematics for my 2 wheeler Fi automatic scooter... 125cc...

Right on the head for the solar panels! Since the govenrment charges us for the water, maybe someday they might charge us for the solar rays we harvest! LOL!

JayY2 (author)2017-09-01

FYI: These systems don't use tap water because too many contaminants, and aren't efficient enough. Use distilled water with baking soda in it. Or you can use urine....

ChrisB473 (author)2016-05-19

don't you only want to add the hydrogen to the gas and not the oxygen. i think if you just add the HHO as is, in it's perfect ratio the propensity it will take is to just reform a H20 molecule and not in acting as a catalyst or fuel accelerant of any kind. There should be ample oxygen in the air mixed with the gas to combust the H2 and ideally it doesn't just form a steam molecule that you paid to separate in your generator and reform in your engine. If you hydrogenate the gasoline, what occurs? I'm sure they've been done on saturating gas with hydrogen and oxygen separately and i'm certain they've been done trying to add peroxides. For God's sake don't try to add peroxides to any fuel to increase its efficiency, just ask a submariner.

JayY2 (author)ChrisB4732017-09-01

If you add just hydrogen you do not even need gasoline, and will have to make much more modifications to use it. The hydrogen STILL needs oxygen to burn, and having the oxygen introduced with the hydrogen is what happens in all fuel systems, no matter what the fuel. Yes, the left over hydrogen and oxygen will turn back to water and drain from the exhaust, but that is after combustion, an the action that causes this is the running of the engine no matter what fuel source you use. Just think of the things that can burn under water or in space: They can do that only because they carry their own oxygen supply. Otherwise, as with any car, whether injected or not, the must have oxygen added. Air has to be added to the fuel, or the car won't run. Cars don't burn liquid fuel, they burn vapors, part of which is oxygen.

RedstoneM (author)2015-10-03

So you make hydrogen from battery power which is generated by the alternator driven by your motor which is supplied by fuel? So you use more fuel to add some hydrogen to the fuel?

bhenry2 (author)RedstoneM2015-10-04

No the car is started off of regular fuel the battery is already receiving enough energy from the alternator so the energy the energy that's being robbed is barely noticeable when the pressure in the hydrogen cell gets high enough the hydrogen fuel goes in through the air intake so when the engine opens to basically inhale air it pulls some hydrogen in too so the car isn't trying to do anything more than it was already doing the difference is is that the car won't have to use as much fuel in the combustion chamber to move the piston down it will use a smaller amount to receive the same input so imagine if this is how it was broken down.

Only an example not real values from an experiment
(1unit of gas + 1 unit of oxygen + spark= 2 units of power

With the hydrogen cell it'll be like this

1/2 unit of gas + 1/2 unit of hydrogen + 1 unit of oxygen + spark= 2 units of power)

In the end you received the same output power with less fuel input and we all know it's cheaper to put water in the tank than it'd be to put gas so the savings would be outstanding. Use this in your daily driver to save gas.

RedstoneM (author)bhenry22016-07-08

Nah, this won't work.

2 units of power + 1 unit of water -> 1 unit of HHO + heat

1/2 unit of gas + 1/2 unit of HHO -> 1 unit of energy + heat

Engines are about 40% efficient, that HHO generator too isn't very efficient. Energy conversion law, you can't get out more that you put into it. (If you would heat the fuel to a few million degrees and the atoms would fuse together, then that would be another thing.)

JayY2 (author)RedstoneM2017-09-01

You do know that diesels use HEAT for combustion, don't you? Heat also helps in combustion of gasoline....... That is why cars when they get to hot "run on" when the car is turned off. And the increased heat from using a HHO supplement? Negligible to non-existant.

SufiD (author)2017-01-02

During the past three years, I've made myself three HHO generators by studying plans on the web and test driven them on three different cars, but all old twin barreled carb types. There's many trolls out there, who are very skeptical, who've never done it, tried them out, yet criticize. The Mitsubishi was a 1600 cc, the Mazda was a 1300 cc and the Nissan was a 1500 cc. The average improvement on fuel consumption was 15 - 24%. Recently, for larks, I hooked on a Shell Solar PV Panel of 45 watts (Panel surface area - 19" X 39") and I was amazed that the production of HHO was quite healthy (My electrolyte base is a mixture of Lab Grade KOH + Distilled water @ a dilution rate of 8 - 10%). Like this article mentions with clarity, HHO is not an alternative fuel, it is simply, a healthy, simple additive. There's a lot of definitive plans around of making HHO work for you, with EFI engines by overriding the O2 sensor using EFIE systems. As far as taxing the alternator and battery is concerned, this is highly exaggerated, it's a load of bull.

i want some help in HHo formation.

sir i have made this hho generator for my electric generator.i insert 8 stainless steal plates. i am giving 12 volt dc with 8.3 ampere.the plates are 5 cm long and 5 cm is marking hho but with less pressure.kindly tell me what to do to increase pressure of hho.that each bolt is attached with 2 electrodes which is in master paint air tite box
and the arrangement of electrode is like that 2 negative plate then 2 positive plates then 2 negative then 2 positive plates. grand total 8 plates
waiting for your kind reply
JayY2 (author)shanu22017-09-01

The system does not have to be pressurized beyond the natural pressure from the separation process. That is what makes HHO generators safer than hydrogen fueled engines using pressurized tanks. But, if you really want to pressurize it and use it in tanks instead of on demand, you can build a compressor to do so, but then it wouldn't be on-demand, nor likely run off 12v car systems.

CharlesC232 (author)2017-04-10

Now does anyone know what the best grade of stain less steel is and how to get ahold of it? I have about twenty voteing mechines with a bunch of stainless plateing in them how can I tell the the grade? Any help would been awsome.
