Hydrogen is the best alternative fuel source to power internal combustion engines. It can be created from water, is abundant in supply, and has been used on engines before. There is a corrosion factor to consider but it can be remedied with a little gasoline in the mixture.
With an on-demand hydrogen generator, the user will not have to worry about dangerous compressed storage containers and toxic fumes.
There is an invention that uses high grade stainless steel tubes and pulsed high voltage to convert water into hydrogen. The invention looks more efficient than all other electrolysis methods I've seen and produces plenty of hydrogen gas.

http://www.icubenetwork.com/forum/viewtopic.php?t=98 It would be nice if someone tested its efficiency and compared to conventional methods. Some have claimed it is a thousand percent more efficient. These claims lead me to believe,
1.) Conventional methods are less than .01 % efficient
2.) Miscalculation
3.) B.S.
There are a few reports of working units on the Internet so I doubt it is a load of B.S. In addition, I have yet to find detailed efficiency calculations on conventional techniques. Maybe someone here can help.
