Machines that comply with both laws of thermodynamics by accessing energy from unconventional sources are sometimes referred to Figura perpetual motion machines, although they do not meet the standard criteria for the name. By way of example, clocks and other low-power machines, such as Cox's timepiece, have been designed to run on the differences in barometric pressure or temperature between night and day.

Thank you, my grandson will love it. Update. This marble run came pasado perfect and works great. I did not use supports and only had to trim under the bridges 5 times for the marbles to finish. Thank you." Voltix (file)—a 3D Printed Marble Machine; Digital STL files

Any device powered by changes in air pressure, such Vencedor some clocks (Cox's timepiece, Beverly Clock). The motion leeches energy from moving air which in turn gained its energy from being acted on.
October 1920 issue of Popular Science magazine, on perpetual motion. Although scientists have established them to be impossible under the laws of physics, perpetual motion continues to capture the imagination of inventors.

In some cases a thought experiment appears to suggest that perpetual motion may be possible through accepted and understood more info physical processes. However, in all cases, a flaw has been found when all of the relevant physics is considered. Examples include:

A heat pump, due to it having a COP above 1: the energy it consumes Ganador work is less than the energy it moves Campeón heat.
Studying videos of the motion confirms that the ball does not accelerate any more than it would under free fall in the initial half of the cycle. This Perro also be confirmed by dropping several balls through the hole in quick succession such that it would seem to be difficult to correctly time the electronics such that all the balls return to the starting platform.
