i just went over this in physics, but if you take a coil, and pass a magnet near it (without touching), you create an emf while you come near it and when you leave. i believe its the Faraday effect/observation/whatever? but with that in mind, i had this idea: if you take some really big coils and put them in space so the orbit the earth say counterclockwise, and then take a big magnet and make it orbit the earth clockwise, and some how hook it all up so that you when the current flows from the coils you say charge a really big battery or something. isnt that essentially free energy? now i understand that most probably the satelite will fall because of the loss in energy, but if you position you coils just right, you could have it bounce sort of every time it passes through one, and maybe once every decade or so prop them up a bit? it sounds really insane but i just thought it might potentially work... any ideas?
