Salt Water as Fuel

[rhertz]

As joe pointed out, fundamental laws of physics state that energy cannot be created nor distroyed, it can only be transformed from one type into another.

Keep this in mind when you pay your next light bill. You are not paying for energy. You are paying to "borrow" energy, or more specifically to transduce it from one form into another. In a since, it is impossible to "waste energy". Rather you can only transform it into a form that isn't as desirable as the one you are looking for, such as heat emitted from a computer or light bulb.
