In May 2022, a video supposedly showing a marble machine in "perpetual" motion was shared to the "Be Amazed" section of Reddit. The video, which showed a marble spiraling down a funnel, dropping through a hole, moving along a curved rail, and then launching back into the funnel where the process would begin anew, drew a few skeptical comments.
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 Figura Cox's timepiece, have been designed to run on the differences in barometric pressure or temperature between night and day.

Ellipsoid paradox surface and rays emitted by body A in the direction of body B. (a) When bodies A and B are point like, all rays from A must be incident on B. (b) When bodies A and B are extended, some rays from A will not be incident on B and may eventually return to A. Conspiracy theories[edit]

The first possibility that will likely occur in discussion is quite simple. Before seeing the electromagnet in the pulvínulo of the device, students might guess that the magnet is always switched on merienda the device is started and is not controlled. This possibility can be removed immediately because if it were always switched on continuously, the magnet would take at least Triunfador much kinetic energy from the ball Figura it imparted to the ball. The second possibility is that the electromagnet is switched on when the ball passes through the hole in the platform: this electromagnet accelerates the ball toward the bottom of the ramp faster than it would accelerate by freely falling under gravity.

There is a scientific consensus that perpetual motion in an isolated system violates either the first law of thermodynamics, the second law of thermodynamics, or both. The first law of thermodynamics is a version of the law of conservation of energy. The second law Chucho be phrased in several different ways, the most intuitive of which is that heat flows spontaneously from hotter to colder places; relevant here is that the law observes that in every macroscopic process, there is friction or something close to it; another statement is that no heat engine (an engine which produces work while moving heat from a high temperature to a low temperature) Gozque be more efficient than a Carnot heat engine operating between the same two temperatures.
