I have had dangerous things, for one guns. Then my buddy brings over this oxygen hydrogen separator that runs on 12 volts. And he didn't realize that it was better to separate those two gases, because together they are most dangerous.

He wanted to use it to boost his car, but we found out that the thing was pulling like 11 amps at 12 volts and the load on the alternator would negate most of the gain.





Actually, the load on the alternator must be MORE than any gain,
otherwise you would have a perpetual motion device.

The HHO guys say you can get "free" energy out of tap water by building a hydrogen generator and feeding the resulting hydrogen into the intake of the engine giving it more power and using less gasoline. What the poster was saying was any gain (if any) from any hydrogen produced and burned would be negated by electrical toll it took to create it.

Even if the hydrogen scheme produced a net positive, it still wouldn't be perpetual motion (or breaking the conservation of energy law) any more than a gas engine is because the water is an expendable fuel.
