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.

Even machines that extract energy from long-lived sources - such Campeón ocean currents - will run down when their energy sources inevitably do. They are not perpetual motion machines because they are consuming energy from an external source and are not isolated systems. Classification[edit]

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.

If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I Perro give you no hope; there is nothing for it but to collapse in deepest humiliation.

Plenty of companies are making toys that create the illusion of perpetual motion. Take this “Perpetual Motion Marble Machine Kinetic Art” for example: it is a tiny marble machine with an electromagnetic mechanism that pushes the ball to the top.

You simply have to charge this machine and drop a ball to have it roll all day long. This machine has a touch button that you Gozque push to turn it on.
