We have been experimenting with a lot of different designs for hydrogen generators. One of our goals was to make a more efficient unit that uses less power and therefore builds less waste heat.

One of these units is attached to this Pontiac Sunfire. My son has been running this car to and from school and work. He has been putting on about 600 kilometers per month. As well, I have been taking it for long drives at night. One thing I found is that different driving styles make a real difference. My son “drives it like he stole it” and this sure puts fuel mileage in the backseat. Even with higher revvs on the engine and faster starts and stops, he consistently got more than 25% gains from running our generator.

We used no electrolytes or baking soda in this unit. Straight tap water only. There were no sensor modifications made to this car. The unit is in front of the radiator and behind the grill, and measures 3.5″ by 18″ long. It draws between 2.5 and 4 amps depending on run time and amount of water conditioning.

This video is of a long drive on a winding road with hills and valleys. Average speed is above the speed limit all the way. As you can see in the video, when I figure out how much gasoline I use I fill the tank to an excessive amount to avoid skewing the results.

A few weeks ago we were testing one of out HHO generators. The video here is from that test. If you want to see how we made an HHO cell a lot like this, see How to Make an HHO Fuel Cell Anode.
Here’s what we show in this clip:
1. the test fuel cell hanging in pure water, with 2 amps DC running through it and producing hydrogen and oxygen (two hydrogen for one oxygen, which is the explosive HHO mixture)
2. the HHO fuel cell in its case and bubbling the hydrogen gas through water, which we timed and caught in a jar to measure production.
3. the HHO hydrogen generator bubbling into soapy water, so we can catch the bubbles to light them with a BBQ lighter. This is really loud, like earsplitting. It’s hard to believe how much force there is in just a little of this gas.
4. the hydrogen fuel cell hooked up and running the HHO to a Ford half ton. We used an older vehicle, just in case something went wrong. Expendable trucks first, please!
