Someone in Japan (where else?) has developed a battery called the NoPoPo that is powered by urine and capable of powering a flashlight for approximately 20 hours. Yes, the batteries are in fact rechargeable. The problem is that they’re AA and AAA sized only which means you’ve got to have some serious aiming skills to fill these things up without causing an unfortunate catastrophe, especially if you’re left in a dark room with no visibility after your flashlight goes out. Thankfully there’s other sources of fuel you can use, including saliva in case it’s one of those times where you just can’t go.

Could be worse. It could be called the NoPooPoo.
