Frosty a LOT of people are using browns gas to supplement the gas, especially diesel, in engines to get better power, milage and better emissions. The only one I know of who successfully ran on water alone was Stan Mayer(not sure that I spelt dat right) and his invention was disappeared....if ya get my meaning. Also, any technology that threatens the oil companies profits in a real way will be suppressed. They have mo money than the climate folks. I know someone that somehow ended up with an experimental fuel injection system on a mustang they bought and made the mistake of mentioning that they were getting 46 mpg (v8) on the highway when they took it to a ford dealer for like the 5th oil change. The dealership did him a solid and replaced the fuel system completely free of charge! Back to 16 to 18 mpg for him. I think the manufacturers and the oil companies are kinda tight.
Anyway I built a browns gas (aka hho) generator for my f150 and saw 5-8 mpg gains. Also, much more power. Do a lot of mountain highway driving and many of the up grades she stoped down shifting due to less throttle be needed.
You will need a large generator to use hho. They sell commercial torches that use it. Willem you will have to do a lot, I mean a lot of fabrication to construct one. It can all be done with simple power tools tho. The hard part is going to be finding all the stainless steel on what sounds to be no budget.
