Old Hard Drives = Free Electricity

tylernt writes "You know all those old hard drives you have laying around? (Raise your hand if you still have RLL or MFM drives... yeah, I thought so.) Well, now there's something useful you can do with them (besides my personal favorite, shooting them): make electricity! While you're at it, you could do something more productive with that old lawnmower, too."

Another post where it looks cool at first, but not really. So the guy used magnets FROM OLD HARD DRIVES (tech connection = yay) to power a standard homebrew generator. Whoopie. Of course, the hard thing, as in all electric generation, is getting the generator to spin, which isn't done with the hard drives. If he had powered up an old computer and used spinning hard drives to run a motor WHILE they were working, and powering a led from the spinning of the hard drives, that would have been cool. Sorry, not an impressive hack.
