The concept of a perpetual motion machine is an enticing one: Imagine a machine that runs continuously without requiring any external energy -- a feat that could make refueling vehicles a thing of the past. While a perpetual motion machine inspires appealing possibilities, most scientists agree that such a machine is impossible, as the very concept -- doing work without any energy input -- defies the laws of thermodynamics. Nevertheless, some researchers have forged ahead with efforts to create ...
