* Red Green attempted to make one in the "Handyman's Corner" segment of the GrandFinale of ''Series/TheRedGreenShow'', using only household items. He hooks up a lawnmower to an alternator that powers a ceiling fan located amongst some corn stalks. The fan chops off an ear of corn when the corn gets as high as an elephant's eye, sending the corn into [[KitchenSinkIncluded a sink]] with a garbage disposal also powered by the alternator. The corn then falls into an oil drum where it decomposes into ethanol, where it gets siphoned back into the lawnmower. Meanwhile, the spare corn seeds gathered by the garbage disposal slide down a downspout to where the corn grows, so the corn keeps on coming. However, Red finds one problem in his "ultimate project". The lawnmower won't start.

* Discussed in the Literature/VorkosiganSaga novel ''Komarr''. One of the physicists Miles calls in to consult determines that the device he's asking her about ''looks'' like a perpetual motion machine. Since she's a competent physicist who doesn't believe in such things, she concludes that it must be drawing energy from the deep structure of the wormholes it gets pointed at -- because there's nowhere else it could be coming from.

* Subverted in the [[WesternAnimation/GadgetBoyAndHeather Gadget Boy's Adventures in History]] episode "These are a Few of my Favorite Flying Things". The villain Spydra succeeds in stealing Leonardo da Vinci's perpetual motion machine prototype. Leonardo takes the theft well because his machine was supposed to prove that perpetual motion is impossible. Cue Spydra yet again suffering a humiliating defeat when her flying machine crashes.

* There have been a few cases of seemingly successful perpetual motion machines, though careful examination has always shown either a lack of credible documentation, or an external power source. In fairness to the creators, some of these cases used energy sources not well understood at the time. One in particular, [[http://en.wikipedia.org/wiki/Johann_Bessler Orffyreus' Wheel]], is still the subject of controversy as to its functioning; however, it is believed to be a deliberate fraud.

* The main focus of the first episode of Literature/TheChroniclesOfProfessorJackBaling is what happens to an engineering professor when he encounters a working perpetual motion machine. Specifically, an overbalanced wheel [[http://www.lhup.edu/~dsimanek/museum/machines/machines.htm]].

A perpetual motion machine of the second kind is a machine violating the second law of thermodynamics -- that isolated system evolves toward maximum entropy. This involves transferring heat from colder to hotter objects without spending additional energy[[note]]the required energy is proportional to entropy and temperature, by the way[[/note]].

* The train in ''Film/{{Snowpiercer}}'' never stops, never needs refueling, and the engine does not appear to be a nuclear reactor.
