Perpetual Motion

APES-XYNBJG

Creating a perpetual motion machine is tantalizing. Is it possible to design a machine that will run forever without a continuous input of energy?

A

Yes. This is the next major source of electricity​ production in the United States.

B

No. The Second Law of Thermodynamics states that with each energy conversion, some energy will be converted to heat, a less usable form of energy.

C

Yes. A perpetual motion machine operates using solar power which makes it possible to get more energy than you put into it.

D

Yes. The First Law of Thermodynamics states that energy can neither be created nor destroyed. Therefore, the energy you put into a machine should be maintained.

E

No. Until we can figure out how to do fusion on a large scale, a perpetual motion machine is not possible.
