Ok this might be a little stupid, but I read those posts about people making their DS wind and water powered. I saw the crank battery for the DS on the Nintendo DS Blog, and I was wondering if anybody had a way of making their DS powered by hamsters. I know it sounds stupid but I think it would be an interesting biology project to see about converting energy from an animal into energy for the DS. Hamsters run on wheels a lot don’t they? shouldnt this then be pretty easy because i just need to attach the wheel to a crank battery!
