Normally, yes. The laws of physics always apply. However, the technique they are cheating people with, er, I mean, the technique they are emulating is a blended fuel model where a small amount of hydrogen mixed into the combustion air stream nets a greater improvement than burning either the gasoline or the hydrogen alone.

See my post above about Uli Kruger and Jonathan Goodwin, a mechanic from Kansas, who has doubled both the MPG and the horsepower of a Hummer by using hydrogen and diesel. At the bottom of This Page , where Goodwin claims his diesel-converted Hummer used hydrogen injected into the cylinders, displacing "half the diesel", doubling mileage and horsepower (and getting a 700 mile range out of the tank).

But there is no free lunch. As far as I can tell, the mileage claims don't take into account the fact that he's paying for the compressed hydrogen; the cost of the hydrogen should be converted into "diesel-equivalent" gallons and added to the total.

I don't think the hydrogen-producing jars under the hood will really work, but they are working on that principle, and able to fool people that way.
