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.  
<p>Very nice work! Man things have come along way since my old hack saw &amp; hand drill.</p><p>I made something similar when I was in high school, bout 35 years ago.... except all I used was a 5 gallon plastic bucket, 2 8&quot; carbon rods from an old arc lamp I found out in the barn, and a heavy duty lamp cord. I screwed the ends of the wires to the copper end connectors on the carbon rods and clamped them to opposite sides of the bucket, filled it with water, &amp; set it in the middle of a concrete floor. </p><p> I should probably mention at this point, being the brilliant teenager I was, I was doing this in the basement. So... I plug the wire into a dimmer box I used for 'experiments', put it on low, it hit the power switch. Immediately, Bubbles!!!! So I crank up the power a bit more, More Bubbles!!!</p><p> Now theres no stopping... The switch goes all the way to 11 baby... &amp; the bucket literaly looks like it's boiling! I figure the water level dropped 2 inches in as many minutes. Now, I know you all know what happened next. Idiot teenage, free flowing volitile gases, box of matches... One strike, a toss, &amp; there was an 8 foot volcano roaring out of that bucket all the way to the rafters, then spreading outward where gas had collected.</p><p>So... After a stunned few seconds admiring my handywork, I killed the power, &amp; the flames died almost instantly. Aside from some darkening and a few scorched corners, no damage done.</p><p>You can replicate this yourself a bit safer using carbon rods from D-cell batteries, or you can get them at most welding stores (or ebay). I use a train transformer to play around now on a smaller scale, but a 12/24v battery charger will work well too.</p><p> I don't recommend trying the AC method I did, but if ya do, do it outside, &amp; do it safe! You can us PVC pipe around each electrode to seperate to gases. I've glued up a few rigs with valves so I could fill ballons &amp; what not.</p>
<p>Wow, that is quite impressive. I was unable to get a flame from an open reaction like that.</p>
The rods where about an inch thick, which is what I 'think' made all the difference. I haven't repeated it again on that scale, as finding decent rods are hard to come by, especialy large ones. I swear some of my best results have been from when I had absolutely no idea what I was doing.<br> I salvage small ones 1/8-1/2&quot; out of AA-D &amp; lantern type batteries to play with. The last thing I made was a micro spot welder, A while back I did the carbon-arc furnace using a terracotta flower pot, that was neat as well, &amp; blinding... LOL :)<br> The old 50's issues of science &amp; mechanics had some of the best plans &amp; experiments. I found the entire hard-bound set at goodwill a couple years ago &amp; snapped it up. All the old 'build your own shop, boat, mini bike, submarine' plans..... todays parents would be terrified.... &quot;Build your own diving equiptment&quot; alone would cause an epidemic of heart attacks... ;)
<p>A lot of those are available online now, but if I ever come across the actual, physical magazines I will be sure to get them. Luckily my parents are pretty chill, so they are fine with me doing crazy stuff in my basement and garage.</p><p>Have you ever taken a look at the Popular mechanics magazines?</p>
I quite agree, sometimes experience can really be a limiting factor in the success of experiments. The epidemic of 0 danger tolerance, and the aversion to DIY projects has gotten kind of crazy over the years. Luckily I have great parents who are really supportive of my plans to launch homemade rockets into the sky or potentially build my own fission reactor in the basement, even if they do ask me to give them a long presentation on the safety precautions that I am taking, most of which they probably will not understand.
<p>Wow. I could not even get through all the comments, so bitter. Anyway, as the note says, this is not an energy generator, rather it is a converter. In my opinion the way to make this &quot;freeish&quot; energy, would be to use an off grid solar energy collection system to power it. If you could get things into place to compress it into a liquid you could use it for a lot of things. The benefit in my mind is having a system that does not rely on batteries which tend to have limited life spans at this time (09-23-2015). I'm not interested in something that will save me money as much as I am interested in having reliable power at a remote location. </p>
<p>Better yet we could power them with fission reactors as they generate a heck of a lot more energy.</p>
<p>How many amps does it draw at 12 volts on a car battery?</p>
<p>In my experience, higher current lead to more hydrogen and oxygen generation, as did higher voltage. The exact amount it draws really depends on your battery.</p>
<p>&quot;This breaks the laws of physics! You can't get more energy out than you put in!&quot; 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 &quot;perpetual motion machine&quot;, 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.</p>
<p>Well, I am not saying that this is not potentially an incredible technology for fueling cars, the energy that converts the water into hydrogen and oxygen has to come from somewhere. In this case it is coming from your car battery, which is charged by burning gasoline, or hydrogen/oxygen in your combustion engine. It is not possible to use this generator to make oxygen and hydrogen, burn them, and use that energy to continue to power the generator indefinitely, as you are subject to diminishing returns.</p>
<p>I guess you forgot that the combustion of the oxyhydrogen mixture will release water vapour.... If we can find an efficient way of condensing this water vapour back into water from the exhaust and channel it into the fuel tank(which im sure we can) it would be quite advantageous:)</p>
<p>... And there's your Perpetual Motion Machine all over again...</p><p>Reminds me of The New York Times crucifying Robert Goddard for saying rocket engines could work in space. According to &quot;the knowledge ladled out daily in our high schools,&quot; &quot;there was &quot;nothing to push against.&quot;</p><p>I guess High School has gotten worse at science since then.</p>
<p>It <strong>is </strong>rocket science... You use more kilowatt-hours (A unit of work) to get the hydrogen by electrolysis than you'll ever get out of burning the hydrogen. Period. End of discussion.</p>
<p>&quot;end of discussion&quot; &lt;-- you sound dogmatic, religiously over-zealous in your beliefs. Of course, you will get nowhere as you stay within the box that the big industrialists have put you in. I hate to break it to you, but you have spent 1,000's being lied to in college, about physics. Hint; There are open and closed loop systems. An open loop system CAN and does (it has been proven) generate extra energy by pulling it from the surrounding atmosphere. Anyone who has watched a lightning storm knows that this exists. A closed loop system, like a brainwashed mind, can not generate anything more than what is put into it. Good luck.</p>
<p>Zzzzz... Well, let me know when you tell the power company and the gas station to take a hike. And good luck catching that lightning.</p><p>&quot;In theory, there is no difference between theory and practice. In practice, there is.&quot;</p>
<p>Hey bro, i replicate your project. :)<br>the Idea is use it as a fuel saver in my car. i now start working in a PWM circuit to control the produce of gas.<br>sorry, dont have any Pictures of the full assembly with the bubbler and hose.<br>thanks for sharing with us your amazing project.</p>
Hi Rafael, does it work for fuel saver for your car? And which car are you driving?
<p>Pretty cool, kinda makes me wish I had gone with a clear housing like that.</p><p>In answer to your question JohnnyI5, it can potentially work as a fuel saver, but really you are only converting excess power generated and stored in your battery back into fuel for your car. Some people say that this improves the efficiency of your gasoline burn as well... I am no expert, but I believe it is definitely possible that this is a factor as well. If you power your car with another energy source, such as a solar panel or a fission reactor, you can convert this energy into fuel and use it in your engine, with or without gasoline, and it should work fine.</p>
Hello sir ....can i use it in my car ?? is that possible ??
<p>You could potentially use it to fuel your car, but you have to realize that you can't create a self perpetuating cycle of generation. This is turning energy into combustible fuel, and when you burn that fuel you are not going to be able to get more power out than you put in. You could, say, power this with solar panels on the roof of your car, generate hydrogen and oxygen within your generator, and burn it in your engine to propel your car.</p>
Is the water clean enough to drink
<p>Its not going to have bacteria or anything in it as long as you got your water from a clean source, however depending on the material you used for the plates and what type of electrolyte you used for the process, you could get a variety of different chemicals and substances in your water. Chlorine pitting can partially dissolve your plates, mixing the water with lead, iron, copper or whatever else they were made of, and I am not sure exactly why, but my water sometimes turned highly acidic after a few minutes of running it. Happened intermitently and inconsistently, so I still do not know what was going on....</p>
<p>How large of a unit would I need to build to help an F-250 Powerstroke get better mileage?<br><br>would the effort result in more MPG?</p><p>And before the whiners start..<br><br>I DO NOT expect to make a diesel run on Hydrogen.</p><p>Just help on the economy.</p>
<p>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.</p><p>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? </p><p>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. </p><p>Mixing hydrogen with gasoline to improve fuel mileage <strong><em>does not</em></strong> 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. </p><p>Using electricity to make hydrogen in order to use the hydrogen as an energy source is a losing proposition. Just use the electricity instead. </p>
<p>If we could just get past the water to hydrogen fuel source we could make a fuel source that will be better for the world and will help slow down global warming we could make anything happen if we put our minds to it.</p>
<p>The best way to stop global warming is to shut down the politicians and their friends that are making billions off a non- human caused phenomena.<br><br>There is ZERO data to show man has any influence.<br><br>There dose seem to be a lot of politically generated hot air, but nothing of value in thatisthere</p>
<p>True but what I am trying to say is carbon dioxide and carbon monoxide aren't doing us any favours with global warming are they so if we can create a fuel that does not produce either of them we could stop carbon dioxide and carbon monoxide poisoning.</p>
<p>&quot;Carbon Dioxide&quot; a naturally occurring gas in the atmosphere that is necessary for all forms of life on the Planet.<br><br>Fauna exhales CO2 after breathing in the oxygen NEEDED to sustain their life.<br>Flora absorbs the CO2 for it's life sustenance and emits OXYGEN.<br><br>Shall I continue?<br><br>This &quot;INSTRUCTABLES&quot; and a place of learning.<br><br>But probably not a place to hold verbal battles over politically contrived 'disasters' that are not happening.</p>
<p>But if we can make a clean fuel source we could solve many problems</p>
<p>And we come full circle to the main thrust of this Instructable.</p>
<p>And one other thing their is too much carbon dioxide and carbon monoxide in the air more than we or the plants and trees need I may be a kid but I know what I am talking about because I am studying this right now so either help me create a clean fuel source or stop replying to me. </p>
<p>Aren't the trees and plants growing faster and greener as a result ?</p>
actually some studies say that too much makes plants grow slower <br>http://news.stanford.edu/pr/02/jasperplots124.html
Are you after coming out from under a rock. Burning fossil fuels like oil are rereleasing the c02 that took the planet billions of years to trap. And were putting it all back up there very very fast. Ive a question for you when they remove all the oil from an area under the earth.what do yoi think happens in that empty void. Take your time to think about that....clearly you will need it
<p>We might be able to pump those voids full of Co2 to keep them inflated .</p>
Hemoglobin. The best viable fuel source with a dark little secret.
<p>With a better attitude I think you would be able to see the potential. You can generate electricity with the solar on your roof, difference of temperature, wind, pressure, kinetic energy, magnets, etc., to build up the hydrogen so that every time you come home you can fill up what has been generated. And I suggest you do a little more research on the energy density of hydrogen vs gasoline. The hydrogen in the gasoline is what's important. Carbon is key because of how well hydrogen bonds to it. Hydrogen will be a large part of the future as it is abundant and &quot;liquid&quot; economically, since it can be easily produced and converted.</p>
<p>You learned your physics incorrectly. </p><p>Not to mention most people can use hydrogen without major modifications to their engine, most people cannot use electricity easily as it is a compleltly different motor. </p>
<p>I'm still waiting for him to find out exactly how much energy would be in a pound of Hydrogen.<br>We still don't know if he meant in a gaseous state or Liquid state.</p>
<p>I filled a balloon with hydrogen and went to weigh it for you, but it floated away :/</p>
<p>Well,</p><p>Obviously you needed a bigger balloon the get a whole pound of it....</p>
<p>&quot;putting a hydrogen generator on their vehicle to create hydrogen that <br>they mix with the gasoline or diesel to get better mileage are either <br>shysters trying to sell a system or deluded users that don't understand <br>physics and conservation of energy&quot; &lt;-- I can tell you don't even know what one of these things looks like OR does. Out of hand though, without even looking or trying, you dismiss the possibility because &quot;science&quot;. Look into Nikola Tesla and see what he proved. He was a lot smarter than me, and definitely you, and the industrialists, after finding out his goals of free energy for everyone, shut him down. Your college education (if you have one) was a lie. Physics' &quot;laws&quot; are partly BS, and meant to keep people from even trying to generate free energy. Maybe you should spend some time out in nature and see what actually exists. Energy is all around us, abundant and free, and ready to be tapped into. We have lightning storms, magnetic north, positively charged earth, its all around us. Why guys like you feel the need to spout off with useless and self-defeating info is beyond me. It is thanks to brainwashed sheep that we are all stuck paying for energy.</p>
<p>Lol</p>
Well said, ChristoP4.
<p>These 'detractors' have been trained to believe that &quot;All possible knowledge has been learned, and All possible inventions have been invented&quot;.</p><p>I asked a simple question and they went to war over the need to protect their knowledge from possibly being proven to be outdated and of no further use to Humanity.</p>
<p>I believe that those who are intending to use a hydrogen fuel cell on a car are not trying to increase mpg, but rather trying to improve their exhaust fumes which is a major source of pollution<br></p>
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
<p>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. <br><br>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 &quot;fly&quot; (enclosed in the engine by itself without outside sources doing the conversion) it is not possible, you need energy to convert water into hydrogen &quot;H20&quot; is water.. The car you are referring to claims to do this with the help of the gasoline engine...<br><br>This is just basic science.<br><br>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.<br><br> You can simply do a google search to prove yourself completely wrong.</p>
<p>I have done lots of research about this and even MythBusters did something about it and yes you can run a engine on just hydrogen or mixed with another fuel to get better mpg</p>
