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.
Since when has this country used intellectual elite as a pejorative term?
He's using a lathe plugged into the mains to supply the kinetic energyy to make the magnets rotate. (Using mains electricity to generate electricity)
I know he's just doing that for the sake of experimentation, but it would have been nice to see some real world figures (ie using wind/water to supply the kinetic energy)
when for $600 I can get one premade with the nice honda name brand on it that runs at 1/2 load for 14 hours on one gallon of gas, is quiter than a lawn mower and includes an inverter, handy 110v outlets, and premade metal frame
