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.

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]

"A very finely made wooden marble machine. Great craftsmanship with high quality wood and components. Item was very securely packed for the 9000 mile trip and arrived safely and very quickly. Very pleased !!" Wooden marble machine, Marble run, Rolling ball sculpture

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.

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?" get more info is not only not perpetual, it is also not very quiet. But the kids and grandkids enjoyed it!

There is something lamentable, degrading, and almost insane in pursuing the visionary schemes of past ages with dogged determination, in paths of learning which have been investigated by superior minds, and with which such adventurous persons are totally unacquainted.

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

Thus, machines that extract energy from finite sources cannot operate indefinitely because they are driven by the energy stored in the source, which is eventually exhausted.
