This instructables is for a friend, showing him how to make a small low cost hydrogen generator. I made this for under 25$ and it puts out about 1 1/2 c a min. After reading many comments on how I could make this better I did.

Step 1: Materials

2" coupling
2" to 1and1/2 inch reducer
2" to 1" threaded reducer
1" threaded end cap
1and1/2" end cap
10 nylon washers
1 nylon bolt with nut
6 stainless steel forks
Poly tubing
Pvc glue and the tools you normally use (drill drill bits etc)
2 stainless steel bolts
2 1/2" end caps
1/2" pvc

Step 2: Next Step

Cut the fork heads off and smash them flat. Discard the all but two o the handles. Drill holes in the fork heads, also in the handles. Bend the ends of the handles and drill holes in the end. Drill holes in the 1and1/2" cap. Put the fork heads on in the order of handle, washer, fork, washer, ect. Bolt them tight then bolt the finished generator plates into the pvc cap. Then drill a hole for the poly tubing.

Step 3: Next Next Step

Glue it together should be self explanatory. Make sure the generator plates fit. (you sort of need them to)

Step 4: The Next Next Next Step

Poor about a tablespoon of baking powder or soda (whatever it says on the box) then add water and screw the lid on. Connect 12v battery (I use a 12v car battery charger you can pick one up from any hardware or auto store). NEVER LIGHT THE END OF THE TUBE. It will cause a flashback and the generator will explode. Submerging the tube in water with. Little soap will work.

Step 5: The Next Next Next Next Step/ Modification to Original Design

After reading what all y'all wrote about how it was dangerous not to have a bubbler. I feel that so I added some easy modifications. First, all the neutral plates in the middle are gone. by bending the fork tips to the outside you can get rid of the neutral plates and make more hho. Second, I added a bubbler onto the generator so that I would be able to add a torch onto it someday. I don't know if you can watch the video but it is just an example of the hho gas in action. NO its not me screaming in the background. Its my mom she didn't know how loud it would be.

<p>Cool project! I might make one with some old stainless steel scraps and some PVC pipe.</p>
<p>you guys your technology is money in Kenya</p><p>Can some one show me how to make free energy</p>
Free energy doesn't exist
<p>Life on this planet gets free energy from the sun all day long.</p>
I've got one on my 150cc Scooter. aquarium tube to breather so gas goes in air intake and now gets 145mpg.
I'm pretty sure that's not true. the production of hydrogen to the usage of it in the fuel mixture isn't efficient enough to make a difference
<p>Installed one on the intake of my Mazda Tribute. Got a power boost. You are supposed to keep driving as you have and you will get an increase in mileage, unless you use the power boost for acceleration and speed. My mpg dropped 3mpg. :)</p>
What can I use this for. like what can I do
What does the bubbler do?
<p>I am new to this but the instructions say use what ever in relation to using baking soda or baking powder. I have read the entire document, but can't find what I need. Are you referring to the box in the picture? These instructions seem to be quite poorly thought out. I need to know how to build the generator and would probably be able to do that, but also what to put in it, and baking powder in spite of its similar name is not really interchangeable with baking soda. Once you fill the chamber and hook up the power do you just heat it up? I saw no other ingredients than baking soda/powder.</p><p>At this point, it sounds like the process would make some form of lye, which is made from pure salt and a similar process to what the instructions above say to do. </p>
All you need is an electrolyte. Table salt works, but will likely corrode. Baking soda is likely what he is using. The electricity separates the hydrogen and oxygen atoms from the water molecules in the solution, producing the gas. No heating up or anything like that (other than waste energy being released as heat from the generator itself).
Overall it would be better to add sodium hydroxide due to its higher energy transfer compared to sodium bicarbonate (baking soda), also you would not want to heat up the water as heat creates resistance when referring to the transfer of energy.
<p>Don't know why my comments aren't being shown...Is the resultant water OK to drink?</p>
Due to the fact that we are splitting hydrogen and oxygen through electrolysis and then reacting them through combustion the result would be pure H2O also known as drinking water.
Sorry - very bad - bad pictures - bad explanation - bad idea.
I could figure it out just fine, made my own.
Made it and I love it, added a bubbler with a safety for pressure. Put on a second tube from the bubbler with a long steel stem valve and currently use it for melting and whatever comes to mind. I plan on hooking it up to use as a main fuel source on a very small homemade jet engine.
<p>Wow - what a hornet's nest over a simple electroysis experiment of splitting water into its component elements. Some of the rubbish, errors, mumbo-jumbo, spelling (cunducting), non-science, beggars belief. If folk are going to make constructive comments, at least get your facts right instead of muddying the waters - chlorine = mustard gas??. Here's a little tip from someone who actually worked with the stuff at 300 bar. Hydrogen burns wth an invisible flame (no carbon present) - use a cold mirror and see if it mists up. And another - if you ever get to piping it at high pressures, hydrogen is such a small molecule, it will find leaks that no other gases will find. Cast alloy regulators leak like a sieve, use machined brass or stainless, and Swagelok fittings. Hydrogen is not to be messed with. If it does go, it will be more than your ears popping</p>
Good advice. I am a boilermaker. Work in oil refineries and hydrogen is some nasty stuff, hazardous wise.<br>Most of the piping is heavywall with flanges being mostly rtj ring gaskets, or ring joint. The flanges tend to be 900# to 1500#. We use freah air a lot or scba packs with 5 min escape bottles which will only last 2 min since you will be scrambling and breathing hard lol. Ussually they will pump in nitrogen to displace oxygen and give you a &quot;window&quot; in time to complete the break in or blinding process. Hydrogen is an awesome product. Lol if there is a leak out there you would be amazed at what droping a wrench or something metal does to you knowing tgat just a spark. Good precationary post and warning.
<p>Chlorine is one of the prime components of Mustard Gas: C4H8<strong>Cl</strong>2S</p>
<p>not prime components, A component, there are 4 whole carbon atoms, 8 hydrogens, 2 chlorine and 1 sulphur atom. its like saying oh did you know, you should never eat tuna, one of its prime components is mercury!!! </p><p>or Vinegar (CH3<strong>CO2</strong>H) it is primarily carbon dioxide! we could suffocate by putting it on our potatoes!!</p>
<p>Again..... PLEASE PLEASE PLEASE... Lets drop the aim of getting transport or comfort energy from water components. PLEASE!!! Water is essential for LIFE and subjecting this also to politics of &quot;energy power&quot; puts the world in dangerous dark dark path. Water molecules must remain ONLY as natures intent to sustain life. </p><p>PS- Hyrdro electric is not power from water molecules. It is power from it's motion as is wind power is not power from air..... but it's motion. These are wise uses of nature.</p>
<p>This is the beauty of it. Burning the hydrogen simply makes water again. None is lost!</p>
<p>Search for Lavoisier or the law of energy conservation. Nothing is create, nothing is loss, everything is transformed...If you are extracting energy from water a portion comes back in form of water the other portion is consumed and yeilds energy. You are consuming water. This beeing said how much water is there on earth?. This ain't no fossil fuel. The earth is covered at 70% by water, you are more then 70% water and everything surrounding you contains water to various degrees. So before mankind exhaust the water from the earth.....</p>
<p>I'm not certain what that adds to the understanding of the subject, fbujold; what I see in responses by the average person commenting here is an appalling ignorance of basic science and chemistry in what I suspect are average Instructables readers. I do believe that some of the people who post need to be called to task for incredibly poor suggestions and weak understanding of safety, of science, of chemistry, and of physics. I wish some of these posting contributors would vet their ideas with folk who have some understanding of engineering, physics, chemistry, elecrtical principles or safety, as the various cases require, before posting half-baked messes.</p>
<p>Also, electrolysis works extremely well with seawater, as it's already salty and cunducting.</p>
<p>Electrolysis of sea water is VERY dangerous because you are not only dissassociating the water but also the sodium chloride that is dissolve in it...</p><p>This means you will be releasing Chlorine gas whis is extremely toxic and corrosive. At all costs, avoid dissassociating seawater.</p>
<p>Chlorine gas was the main chemical weapon during WW1, right?</p>
<p>I would be willing to bet that the chlorine gas was to sea water contacting the actual battery and its acids and NOT the process of electrolysis.</p><p>I have tried using sea water and it gets VERY hot in a small unit dissipating the heat was the biggest was a problem as my experiment was in a glass mason jar. Mine had a bubbler and regulator to control vacuum lose made from an aquarium stone and rainbird regulator.</p><p>To be honest I didnt see that much difference between having a anode cathode to just the bubbler. As a mechanic I know that injecting water vapor directly into the combustion chamber increases HP, one of the old wwII fighter planes had a water injector system to give extra HP in emergencies but cant remember which one. and it was using high amounts of water I think. </p><p>Water doesnt compress which would make it the best hydrolc fluid if it wasnt for the rust. That is how it increases cylinder pressure and HP.</p><p>One thing I do know is it cleaned my spark plugs, if you have ever changed a head gasket or know the old trick of pouring a dab of tranny fluid in the old carburetor you know why.</p><p>If you have an old car with not many miles on it left, water vapor seems okay but again you face RUST in the vacuum system.</p>
<p>Friend2002 you could use Peltier unit and radiator in order create (a small amount) power while dissipating the heat.</p>
<p>Check your engineering and efficiencies: Peltier units are notoriously inefficient electrical generators, or converters of heat differential to electrical energy. In this life of the device you'd never get repaid for the cost of installing it. Use Peltier devices where you have no other means to generate power.</p>
<p>&quot;That is how it increases cylinder pressure and HP&quot;<br><br>Um... WHAT?<br><br>The increase in HP was due to the water droplets flashing to steam (water expands to 1,700 times its initial volume when it transitions to steam at standard temp and pressure) when exposed to the combustion of the fuel/air mix in the chamber of each cylinder.</p>
<p>I forgot to mention that part, figured everyone already knew how a choo choo worked and the fact that I have never seen one of the ww2 wep system water injector , the fact that water is non-compressible liquid figures into the mix as well. </p><p>What I always wondered about is what would an oil+liquid o2 powered engine possibilities be.</p><p>Since you seem to be in a teacher kind of mood, how would you go about making it work?</p>
<p>The general non-compressibility of water is not relevant to water injection in internal combustion engines. Drop that from the thread. It is not aiding anybody's understanding of internal combustion engine modifications. No more comment on that.</p>
<p>&quot;an oil+liquid o2 powered engine&quot;<br><br>Well not quite an &quot;oil&quot; but many rocket engines run on kerosene and LOX<br><br>As for using water to boost performance in an internal combustion engine there are several commercially available kits. <br><br><a href="http://www.aemelectronics.com/?q=products/water-methanol-injection-systems/water-methanol-injection-kit-for-forced-induction-gasoline-engines" rel="nofollow">http://www.aemelectronics.com/?q=products/water-me...</a><br><br>(no connection ever to company)</p>
<p>there were several WWII airplanes that used that technology, probably the most famous was the P-38 lightning only trouble was if you used water for more than a couple minutes they had to overhaul the engine </p>

I would take that bet... The mechanism was really electrolysis...</p><p>You can add salt to Hydrochloric Acid all day long and not release Chlorine...</p>
<p>Yes, you can add salt to hydrochloric acid all day and not release chlorine. You can add salt to water all day and not release chlorine. And that is just as relevant to this discussion... Batteries use sulphuric acid, not hydrochloric acid. And when sodium chloride reacts with sulphuric acid it releases hydrogen chloride gas, also known as hydrochloric acid when dissolved in water.</p>
<p>Pure Chlorine gas was the first war gas (used by the Germans in WW1)</p><p>and it killed and maimed thousands.</p>
<p>Yep! Also Known As Mustard Gas... It would literally burn your lungs out while you were still alive... A most horrible way to die.</p>
<p>Chlorine is not mustard gas. Search for mustard gas and learn how it is made and of what, etc.</p><p>Chlorine gas can kill but it is not mustard gas.</p><p>I inadvertently released a small cloud of chlorine gas in my high school chemistry room creating a faint but noticeable smell of a swimming pool. Nice green color cast...</p>
<p>Sorry, chlorine is one of the primary ingredients of Mustard Gas (C4H8<strong>Cl2</strong>S)</p><p>look it up,,, I did.</p>
<p>As I said, chlorine is not mustard gas (even though it is one of the ingredients). Hydrogen is not mustard gas. Carbon is not mustard gas. Sulpher is not mustard gas. The four in the proper proportions can be made into mustard gas.</p><p>Hydrogen is not water but when combined with Oxygen, again not water, create the compound water.</p><p>Chlorine and mustard gas where used in WWI.</p>
<p>I'm at the point where if I comment, I will violate the 'be nice' policy. Please refrain from distributing your misinformation.</p>
<p>That would be Phosgene Gas.</p>
<p>Chlorine gas was most certainly used as a chemical weapon during WW1, but the main gas (responsible for about 85% of deaths from gassing) was phosgene gas (nothing to do with phosphorous, despite the similarity of the name). </p>
<p> saltwater pools use a generator that turns salt water into chlorine and sodium . When the chlorine in the water attacks bacteria it converts back into table salt, Chlorine gas is made completely differently.</p>
<p>Unless you have a way t burn the sodium in the chlorine, that will not happen... besides who wants to swim in a carcinogen that you absorb through your skin??? </p>
<p>What about when I inhale the vaporized chlorine in my tap water when I take a hot shower? </p><p>Doesn't tap water have chlorine too? </p>
