QUOTE=MEP001;9669]They don't do what they claim. The amount of hydrogen it can generate is negligible. Besides, it takes electricity to break down water into hydrogen and oxygen, and the current draw on the alternator increases fuel consumption. It's impossible to get more hydrogen energy than the energy it takes to get it, otherwise you'd be talking about a perpetual motion machine which can actually create energy.[/QUOTE]
That's not entirely true in this application. It takes more energy to break the hydrogen oxygen bond found in water than the energy we get in returning the hydrogen oxygen bond as stated. If the application of the hydrogen was used in this way, we would have a net energy loss due to the transfer of energy thru heat, sound, etc. The perpetual motion reality would fit in this application. However, if the free hydrogen we used energy to seperate can be used in a seperate chemical reaction to increase the mechanical energy gained from burning gasoline, we have the potential to see an energy gain. Gasoline engines are highly inefficient, losing a great percentage of its energy through uncomsumed fuel. If hydrogen can be used in this application to extract extra energy thru a more efficient burning of the fuel, than it is plausible. The perpetual motion reality doesn't apply in this instance because of the introduction of stored energy in gasoline and the potential of a secondary substance increasing the extraction of the stored energy.
This does not mean that this hydrogen generator works however. Without personally knowing the energy impact hyrdogen has on gasoline energy output and the resulting energy it takes to break apart water, I can't say it is effective. I'm assuming more people would be using this if it were in fact true. Plus, I think the oxygen would be more effective in increasing fuel energy extraction than the hydrogen.
