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


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


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.


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


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.


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