It's neat and all, but it's still using magnets and they will lose their charge eventually.

*requeue for that last vote!

oh. right.

Joe, magnets do not have charge.

I'm going to guess this is point-and-laugh sift and go ahead and put this in *terrible.

Comment hidden because you are ignoring dag.(show it anyway)

Not a perpetual mostion machine, but cool little magnetic motor. He should be happy with just that.

Can someone explain the science behind this one? Quite a cool little device. Absolutely not perpetual motion, because they're, well, bullshit, but still very cool.

A magnet in motion will appear as charge. Charge can also refer to something that appears to supply energy, from a battery to a sports drink. So Joe's statement works, even if it's not literally true.

His point definitely still stands; a magnet is a just a battery with a fixed supply of energy stored in it. A flashlight battery stores energy chemically and that energy is tapped via a flow of electrons; the more the electrons flow the weaker the battery gets. A magnet stores energy in the orientation of the spins of its electrons and that energy is tapped by moving objects through the magnetic field; the more work performed by the magnetic field the weaker it gets.

So any device where magnets are fundamental to its design can not be a perpetual motion machine. All this perpetual motion nonsense on youtube is apparently from people who haven't even mastered high school physics.

Ya, I don't see why we keep going back to perpetual motion. Energy can not be created so it has to come from some place. I think instead of looking at snake oil energy generators, we should be looking at ways to convert energy that we have wasted back into useful energy. For example, my computer takes in electrical energy and converts it into different things, such as heat energy or kinetic energy. My monitor creates light energy. What if we could convert all that heat (that wastes even MORE energy on cooling) back into electrical energy? That would be (theoretically) possible and would not wear out over time. If we could reverse entropy, we could have essentially unlimited resources.

it may not be perpetual, but with a bit bigger design and maybe some bigger/stronger magnets it could be used as an indoor emergency generator (if it works with resistance) so its not a Horrible idea. altho i agree, we need to stop trying to get free Energy and concentrate on just getting efficient.

You may not believe me but this is EXACTLY why I quit smoking pot.

Actually, a perpetual motion machine is within the bounds of physics. Perpetual motion just means the motion never stops, which would require no energy leaving the system.
