what is the clostest anyone has come to an perpetual motion machine?

Question

a true perpetual montion machine not an energy convertor or anything like that

Answer 1

I gather that one can set up an electrical flow in a superconducting loop.
As long as the conductor remains superconducting this would probably be the closest man made perpetual motion machine.

Answer 2

If you are talking about the "classical" type of PPM, wherein energy is extracted from it without affecting the motion of the machine, zip-no-nada-even-close. To do so is contrary to some very thoroughly tested physics and mathematics. You cannot create energy. It's very counter-intuitive once you understand the nature of the universe, more so even than the idea of propelling yourself through the air by flapping your arms. At least flight in that manner is, under some conditions, possible; a PPM is not.

Now there are many things that go on in the universe "perpetually", or at least virtually so, such as electrons orbiting a nucleus or planets orbiting stars, but these motions do not require energy. They are simply examples of "what is in motion stays in motion..." under the influence of fields. But the instant you derive any energy from such bodies, they will be affected. The electron will change shell or lose energy in some other way, the planet's orbit will drop slighty, etc.

Energy/mass cannot be destroyed or created, only converted from one form to another.

There is no approxixmation to a mechanical perpetual motion machine.

not going to happen. always need more energy. running out of ener.... _ _ _ _ _ _ _ ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Actually at one time someone suggested there was a whole field of unseen untapped energy available. Something like xrays or other solar. How to reasonably use it for purposes we consider useful is the question.

Other than that perpetual motion type devices belong to the kids. They won't tell you where to find them or get them. Ask parents, kids are the keepers of the pmm.

Answer 5

6 inches.

Answer 6

not even close
