Did your gadget just run out of juice and there isn’t a RadioShack around for miles? Not a problem if you have this "rechargeable" NoPoPo (No Polution Power) battery. Just … um, pee into it:
The Nopopo batteries use a combination of magnesium and carbon that can be mixed with a variety of fluids (including urine) to produce a charge. These batteries only last around 500mAh, which is far less than your average alkaline AA battery, but at least you won’t have to kill the earth to recharge them.
