I drink enough beer that these urine-powered AA batteries could save me hundreds of dollars a year. Ok, not really, and I don’t really have any devices that aren’t rechargeable these days, except maybe my remote control, but I’m sure someone, somewhere (Japan!) will find these little guys very useful.

The makers are claiming one “full” battery can charge a mini flashlight for up to 20 hours. That sounds a bit outlandish to me, but whatever.

Notice how I made it through this entire post without one pee joke? I’m good like that.
