A '''Perpetuum Motion''' (lat: eternal movement) device is a hypothetical machine that can produce work indefinitely without energy source or produce more energy than they consume.
A great number of inventors claim that they have build a perpetual motion machine, but none of them could prove it. Often these claims were made by fraudsters and scammers. Since such a device would violate the laws of thermodynamics, it is also scientific consensus that it is impossible.

From a theoretical point of view these machine are classified by the law they violate:
*Perpetuum Motion device of the first kind: This machine produces energy without input or more that it consumes and violates the first law of thermodynamics.
*Perpetuum Motion device of the second kind: This machine converts heat to mechanical energy. Since this cools the environment, it cannot go on forever and violates the second law of thermodynamics.
*Perpetuum Motion device of the third kind: A machine that can run indefinitely without doing work. Since friction and other interactions with the environment cannot be avoided, such a machine cannot be build (but one can come very close)
==Examples==
* [[Hydrino]]
* [[Joe-Cell]]
* [[Perendev-Group]]
* [[Steorn]]
* Devices of [[Leslie Szabó]]
* [[Testatika]]
* Concepts of [[Claus Wilhelm Turtur]]
* [[Wasserauto]] <!-- Deutschen Artikel prüfen und besseren Namen finden-->
* [[Felix Würth AG]]
