I can see where you might think that, Nateman, but you’re looking at it the wrong way. As I see it, the Blacklight has simply releases found a more efficient way to release a larger amount of the tremendous energy naturally stored in the hydrogen atom and then uses a fraction of that energy to disassociate more hydrogen from water to produce more energy from those atoms and so on. No energy is being put back into the same hydrogen atoms to restore them back to their original ground state once the energy is released. That’s a misconception I also had originally. Once the lower energy hydrogen is produced, being highly reactive, it either combines with itself to form a gas molecules, or combines with other elements to form hydride compounds. If you look at it that way, it’s no more “free energy” than when you burn gasoline in your engine and convert that fuel into lower energy byproducts. When you look at it that way, it makes more sense, at least to me anyway.
This is where the logic all brakes down. Lower energy states are not "reactive". They are stable.A car high on a hill will coast downhill quite naturally. Once it reaches it's low energy state at the bottom of the hill it's not going to become "reactive" and roll uphill to the top again!
