I recommend Roy McAlister, president of the American Hydrogen Association. After looking into Hydrogen and why it hasn't been made a reality, I came across the individual previously mentioned. Although I thought purchasing three of his DVD's and his book would be another dead end an associate and I converted a small lawn mower engine's carburetor by removing it and feeding a Hydrogen fuel line directly behind the intake port. The mower runs just as good or even better than when it was on gasoline.
