Magic Nopopo Batteries Recharge With Urine


By Luke Anderson

I’ve seen a lot of interesting ways to recharge batteries in the last few years. Most of them involve some form of solar, wind or some other alternative energy source. Never have I seen a battery that get a charge from me peeing on it. Okay, you don’t just pee on it, but it does recharge using urine.

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.
