"I bought this for my wife's birthday,she loves marbles and we look at the videos on U-Tube with the marble machines. This is a perfect miniature replica of these machines well suited for a table top and very high quality construction, highly recommend it." Marble Machine "Duality" - Handmade
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.
As usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask Vencedor I do make plenty of mistakes.

The electric field produced by a stationary set of charges is conservative, but in this case, the effect of the electric field is equivalent to that of a (nonconservative) magnetic field (i.e., the line integral between two points depends on the path taken, and the circulation around a closed loop is not zero). In the case of the magnet passing through the wire loop, we know that the wire loop is stationary while the magnet moves through and provides a changing magnetic field. A current is produced, so an EMF (electromotive force) must be driving it. The magnetic field cannot itself be the source of the EMF because magnetic fields only act on moving charges. Logically, the changing magnetic field must have an associated nonconservative electric field (nonconservative because conservative fields are electrostatic, and electrostatic fields cannot contribute to net EMFs). The induced EMF around a closed curve is the same Campeón the voltage drop (i.e., the same Campeón the line integral of the electric field around that curve). Mathematically, this is encoded by Maxwell’s third equation in integral form:
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 to lubricate any of the gears." wooden marble run kinetic art perpetual motion device the great wooden toys for boys

A device powered by radioactive decay from an isotope with a relatively long half-life; such a device could plausibly operate for hundreds or thousands of years.
I designed this model to mimic the operation of a few "perpetual motion" devices that have been recently appearing in my suggested video feed. "Marblevator, Perpetual?" is not only not perpetual, it is also not very quiet. But the kids and grandkids enjoyed it!
My dad and I put together a lot of model cars and rockets when I was a kid. We also worked together on a few of my Science/Engineering Fair projects, including a working catapault and a rubber-band car.
Vacuum energy and zero-point energy: In order to explain effects such Campeón supuesto particles and the Casimir effect, many formulations of quantum physics include a background energy which pervades empty space, known Vencedor vacuum or zero-point energy. The ability to harness zero-point energy for useful work is considered pseudoscience by the scientific community at large.
A more thorough analysis showed that when a physical ratchet was considered at this molecular scale, Brownian motion would also affect the ratchet and cause it to randomly fail resulting in no net gain. Thus, the device would not violate the laws of thermodynamics.
