A lot opf people imagine that it could be possible to harvest energy from the power of magnets. But they usually don't know thermodynamics. They think,it would be possible to create a perpetual motion machine.
After all such people see the power of magnets as someting pulling or pushing someting, like gravity pushs. But even gravity needs differential of potential to allow harvest energy, otherwise we would have generator to harvest it.
The most absurd example of ignorance about thermodynamics came in the shape of a TV News about a car moved by air, compressed air engine. The car came with a home compressor to someone be able to compress the tanks in home. In the end of the reportage the narrator said :
