We get some energy out of it all for us to use.

In the case of HOH, we get some energy out of water too. Water is a fuel, just like gasoline. Unfortunately, preparing water (electrolysis) takes a lot of energy, actually more than we get out of it by combustion of H in the engine.

At least, for me is so. In one case algebraic sum is negative, in the other is positive. Is a practical thing. Laws are there and practical things are here. And they BOTH work.

This is the way I see it.

So for the 20% utility case, you add the "HOH" system and then get 18% or less utility. And you would consider this an option?
