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."

How sure are you? I remember reading about some robot lawn mower that "digested" lawn clippings using a chemical process in order to provide the power. A self-powering machine doesn't have to disobey the laws of thermodynamics. . .

that's awesome

i work with a guy who amazed me with his last hard drive feat. he gyrostabilized a moped with some old hard drives we had laying around. i'm not quite sure how he did it, but it was something to do with the simple gyrostabilizing force from a few hard drives spinning would stabilize the moped. don't ask me, i didn't do it.
