Mini Hydrogen Generator





Introduction: Mini Hydrogen Generator

About: I am a creator and am a ghost and scorpion pepper grower and also like to invent complicated ways for things to get done for no reason what so ever

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.

    can i have the complete information about the project to finish my doccumnetation .plz can u give ittt

    Cool project! I might make one with some old stainless steel scraps and some PVC pipe.

    Life on this planet gets free energy from the sun all day long.

    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

    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. :)

    What can I use this for. like what can I do

    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.

    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.

    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.

    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.

    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.

    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

    Good advice. I am a boilermaker. Work in oil refineries and hydrogen is some nasty stuff, hazardous wise.
    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 "window" 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.
