Ok, I'm a learner at heart....so bear with me. I understand the logic of not being able to put back what I take. Yes, there are losses. But one thing that has always made me scratch my head and think, "why doesn't this get mentioned?" is: Doesn't the alternator always generate more current than we need? I don't know about these newer cars, but with older vehicles, one could use the battery to start the car, and then disconnect the battery altogether and run the car off of the alternator alone.

So using that example, can't the alt run the car, and the battery run the electrolysis unit?

AlaricD: The gains would be Combustion Efficiency. With the Aquatune system, some unconverted H2O does get injected into the comb. chamber, and because it is displacing available oxygen, the o2 sensor reads this as rich, and then leans out the a/f ratio. (am I right on the o2 sensors functionality? More o2 in the exhaust reads as lean, and less reads as rich) <--this was explained to me by the owner/inventor Nick Foy. This is why the Aquatune requires no external sensor adjustments. The gain is a leaner A/F ratio which saves gas in the long run.

But anyhow, help me understand how an engine, that is turning an alt with a belt 100% of the time, uses more gas to replace current losses. Does the alt increase resistance (and therefore use more HP) when it is replacing lost current? If it does, then I could see more gas usage to make the electricity we lost during electrolysis.
