I have built a couple of Hydrogen boosters. I have backed of a little, but have not abandoned them. But I now am working with what I can and evaporative booster. It requires no voltages, additives, electrolytes and is extremely low cost. It utilizes the vacuum of the engine to slowly vaporize water. The benefit of hydrogen burning in the engine still occurs and engine performance is enhanced. Hopefully by the end of the week I will see and increase in mpg. The quickest way to see all of this is to go to web.hometel.com/~tron. You have to type the url in by hand as written ~ is the key above the tab key. I also provide many like that can be of help..... I do not sell anything but provide all my information as open source. Open source means that whatever is not already covered by a patent cannot be patented and remains free to the public. I figure this is the best way to keep the knowledge form becoming hidden for whatever reasons.
