Acerca de Perpetual Marble Machine Kinetic

The principles of thermodynamics are so well established, both theoretically and experimentally, that proposals for perpetual motion machines are universally dismissed by physicists. Any proposed perpetual motion design offers a potentially instructive challenge to physicists: one is certain that it cannot work, so one must explain how it fails to work. The difficulty (and the value) of such an exercise depends on the subtlety of the proposal; the best ones tend to arise from physicists' own thought experiments and often shed light upon certain aspects of physics.

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.

Brownian ratchet: In this thought experiment, one imagines a paddle wheel connected to a ratchet. Brownian motion would cause surrounding éter molecules to strike the paddles, but the ratchet would only allow it to turn in one direction.

I suggest "dry"- assembling a few components ahead. PROS: This is a heavy duty set. I like Ugears, Woodtrick, etc - but those super-light weight wood makes them delicate. Also, unlike those other brands, you don't have more info to lubricate any of the gears." wooden marble run kinetic art perpetual motion device the great wooden toys for boys

Any device powered by changes in air pressure, such as some clocks (Cox's timepiece, Beverly Clock). The motion leeches energy from moving air which in turn gained its energy from being acted on.

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 Gozque 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.
