An electric car powered this way could recharge its own batteries forever, and a clock could automatically rewind itself for years. But there is a reason why perpetual motion machines remain in the realm of fantasy; it's the Laws of Thermodynamics. Some inventions may appear to run by perpetual motion, but they usually rely on a hidden source of external energy.

Both the First and Second Laws of Thermodynamics keep the perpetual motion car in the garage. According to one portion of the First Law, energy cannot be created or destroyed, only changed to different forms. The batteries that power an electric car only contain a fixed amount of energy.

Is perpetual motion possible? According to Frey: No, but things can be engineered to approximate or mimic it.

Only by engineering a solution by which an object in motion can consume some store of energy or gather energy from an external source can we approximate perpetual motion.
