I was thinking a few days ago about these things
It's a kinetic subwoofer... so to speak. You bolt it to your couch, hook it up to the sub channel of your home theater, and it jiggles your cheeks when a movie's playing rumble.
But in reverse, wouldn't it generate juice?
Could you bolt it to an unsprung part of your suspension, wire it through a rectifier to a DC-DC supply (as in this thread) and charge your battery with suspension movement? Sure, it would be marginally more unsprung weight and would have some effect on damping (energy isn't ever 100% free and the relative stiffness would change with load..) but it'd sure be whimsical anyway
