What's that you say - perpetual motion is impossible?   My, you're a difficult one to please.   The electrons in the molecules of rock formations have been spinning steadily for millions of years without stopping - at what point will you agree that they are in perpetual motion?

 

So, why don't electrons run out of energy and just slow down to a standstill?   The universe is a seething cauldron of energy with particles popping into existence and then dropping out again.   If the equation E = mC2 is correct, then we can see that a tremendous amount of energy is needed to create any form of matter.   Scientists remark that if we could tap even a small part of that energy, then we would have free energy for our lifetime.
