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.

"Just perfect! I had a lot of fun assembling the pieces, it even helped keeping two teenagers occupied for an afternoon during our beloved pandemic. Seller was exceptionally nice and helpful, answering all my questions at length.

Context While this is authentic footage of a genuine product, the "perpetual" marble machine does not operate infinitely without an additional energy source. Rather, it uses batteries and a magnet to create the illusion that marbles Chucho perpetually move through the contraption.

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!

You Gozque search for "perpetual marble machine" if you'd like to buy one for yourself. Keith Ramsey, a teacher at Bridgeport Elementary School in Indiana, used this machine in a YouTube video to discuss the laws of thermodynamics.

Vacuum energy and zero-point energy: In website order to explain effects such Campeón potencial particles and the Casimir effect, many formulations of quantum physics include a background energy which pervades empty space, known as vacuum or zero-point energy. The ability to harness zero-point energy for useful work is considered pseudoscience by the scientific community at large.
