Inspired by this thread https://www.physicsforums.com/showthread.php?t=451674, I had an idea!
And it is just that: an idea. Can anyone tell me if it would work, in theory? And if not, why not?
So, passing a magnet through a coil of wire produces an electric current. But it will always take more energy to propel the magnet than is produced.
Would it be possible, in theory, to put a magnet into a low Earth orbit and have it pass through a vast coil as it orbits the body? It would take no additional energy to keep the magnet moving, and it would constantly be producing current.
Well that was my idea. Could it work?
For the record, I had the idea on page one of that thread, before post 20 where Russ Watters states...
Before.
By the by, I am currently accepting job offers from nasa, for more blue sky solutions.
Hope I didn't break any rules posting this. Not sure where to put it either.

so obviously it is possible to set an object into essentially perpetual motion - it can be done with an orbit
