Since at least the 12th century, man has sought to create a perpetual motion machine; a device that would continue working indefinitely without any external source of energy.

A large scientific contingent thinks such a device would violate the laws of thermodynamics, and is thus impossible.

Could it be that as a race, we don’t fully understand the laws of physics and such a device may indeed be possible? What would the ramifications be if we could actually build a perpetually moving device?
