guess the idea wasn't that original
Another thought on maybe making the bike power more efficient would be to keep the drive tire on it and run the generator geared off the wheel somehow? that way you could fill the tire tube with water or cement so that you could have a freewheeling wheel that would keep momentum, if you stopped peddling for a second. that way you could get more consistent output from the generator? I like the cordless drill idea
I have access to a bunch of them with batteries that wont hold a charge. Is there anyway that a charger could be used backwards as an inverter? hook the drill directly to the charger bypassing the battery?
