Crazy idea that popped in my head the other day.
Two words.....
Potato battery.
Why go through all of the trouble of recharging batteries when you could just through in another potato? (If we could get it to work
) I just thought that that would be an interesting. They have already started that (I think anyways) by making the potato alarm clock, and plus I have made and electro-magnet with a potato battery about a year ago.
And afterwords,
MASHED POTATOES!!!
EDIT: By the way, I think this is a good idea. It will surely keep us CD addicts busy this summer.
Edit:Fixed the Potato problem
