http://auto.howstuffworks.com/how-a-hydrogen-boosted-gasoline-engine-works.htm Thought I would again find out if anyone else has explored the Booster for fuel saving. The auto industry is trying to gear up with this idea as in the site above. I am going ahead and building a unit with materials in my shop and installing it on my Ford 460 engine. If the unit does give a 20 percent+ saving I won't have to wait for someone to take care of my fuel. Mythbusters did try one but it failed as they tried to run it at 100 percent which was not the design; the engine did run on 100 percent Hydogen from a compressed bottle of Hydrogen.
