HHO Generator – Water to Fuel Converter

For this project let’s build a sexy looking generator that uses electricity to convert water into an extremely powerful fuel! Here’s how to build an Oxy-Hydrogen generator from scratch.

I’ve been getting a lot of requests for build plans, so I made a 23 page .pdf file you can have for $20 (This helps compensate for the 3 days it took me to make them). You can get them here:

Everything you need to know should be in the video, but the plans have templates for the stainless steel plates, a parts list with SKU numbers, pictures, instructions, and expanded view diagrams of the systems, including an alternate “all ABS” option.

This is not a “free energy” device, “over unity” device, or a claim to be the solution to the worlds energy crisis. This is a project I did to experiment with the electrolysis of water, and the resulting gasses collected.

Project History & More Info:

The generator requires electricity to electrolyze H2O (water) into gas. The resulting mixed gas is sometimes referred to as Oxy-Hydrogen gas, which is 2 parts Hydrogen (H2) and 1 part Oxygen (O2). I typically hook this up to my car battery while the vehicle is running, so the alternator takes most of the load. On 12 volts I get about 1.5 liters/minute, but when I want to make the gas faster, I hook 2 car batteries in series for 24 volts, and this exponentially increases the gas production to over 5 liters per minute.

Current draw seems to be around 20-50 amps depending on whether you use 12-24 volts. High current draws mean the electrolyte heats up, and if left too long the plastic can warp or melt causing structural failure.

Some people ask why the plates aren’t all electrically connected. The plates that aren’t connected are called “floater” plates, or “neutral” plates. There is too much information to post about them here, so do a google search, or check out websites like for an in depth explanation of the theory.

I used KOH as my electrolyte because research suggested it was the best. I haven’t experimented with other electrolytes, but have heard that salt, sodium hydroxide, vinegar, etc could work, but will dirty and may corrode the plates. Potassium Hydroxide keeps the system clean, however, it is caustic, so be careful if you choose to use it. You can probably get away with about 2-4 teaspoons of KOH per 6 liters of water.

This system produces an extremely powerful OxyHydrogen gas. When the gas is used, it simply turns back into water, and that’s good for the environment. However I believe it takes more electric energy to produce the gas than is obtained from the gas. This device merely converts the energy from one form to another, with given losses.

As long as you have enough electricity, the amount of water already in this system is enough to produce thousands and thousands of liters of fuel. Some people say this is the fuel of the future. Either way, it’s a very powerful gas!
