A {{w|perpetual motion machine}} is a hypothetical device that is supposed to move infinitely with no external forces helping it, thus providing an unlimited source of energy. The existence of such an object would contradict the laws of thermodynamics, so perpetual motion machines are known to be impossible. | A {{w|perpetual motion machine}} is a hypothetical device that is supposed to move infinitely with no external forces helping it, thus providing an unlimited source of energy.

In the comic, Randall says that he posted to a forum dedicated to the idea back in 2004, and the thread is still active — it kept on going forever, like the perpetual motion machine they desire (in contrast with real attempts to build such a machine, which all stop quite soon). Of course, the reason the thread continues is that its advocates continue to add energy to it, in the form of comments. "Hot air", if you will. |
The {{w|second law of thermodynamics}} states that the {{w|entropy}} of an ''isolated'' system never decreases. [http://www.youtube.com/watch?v=2knWCuzcdJo See this video about entropy]. Thus, even if you could build a perpetual motion machine, you wouldn't be able to use it to produce energy that could be consumed by another device. | The {{w|second law of thermodynamics}} states that the {{w|entropy}} of an ''isolated'' system never decreases.
