Original Note:
Perpetual motion machines aren't possible because they violate several thermodynamics rules. For example, you can't extract more energy by introducing less; you can only aspire to transform it from one kind into another (in a car, from chemical to mechanical energy). https://en.wikipedia.org/wiki/Perpetual_motion
