liquid chargeable batteries? charged by urine???? or blood??? :0

I found these batteries that are liquid-chargeable (u can apparently use urine or blood to charge them too). I have never seen em before, there pretty cool, there is video of them from 08' so i guess im pretty late. Japan Trend Shop | NoPoPo Eco Water-powered AA Batteries

wow Japan just get more weird every day, kinda cool though except "Can be charged up to five times"

I still remember going to Japan on the the way to Iraq, I was so thirsty, but did not have the $$$$$$$$$$$$$$$$ for a Pepsi, but for a buck I got a shrimp flavored soda from the vending machine.

Nice find on this though, very crazy batteries. nopopo, nopoopoo would have been better, cause I thought you were S%$it ing me when I saw the post. at 6 bats for 57$ plus 15$ shipping I can suppress the urge to try them for now.
