class of proposed machines that violate one of the Laws of Thermodynamics. Perpetual motion has been recognized as extrascientific since the late th century, but proposals and patents for such devices continue to be made to the present day.

[solitaire] Perpetual Motion is a Patience game which has the objective of discarding playing cards from the tableau. It is also called Idiot`s Delight because of the time-consuming process of the game. ==Rules== The tableau is made up of four piles/columns.

Perpetual motion is motion that continues indefinitely without any external source of energy. This is impossible in practice because of friction and other sources of energy loss. A perpetual motion machine is a hypothetical machine that can do work indefinitely without an energy source. This kind of machine is impossible, as it would violate the f...

Idea that a machine can be designed and constructed in such a way that, once started, it will do work indefinitely without requiring any further input of energy (motive power). Such a device would contradict at least one of the two laws of thermodynamics that state that (1) energy can neither be created nor destroyed (the law of conservation of ene...
