The Boy Genius Report: "This has to be one of the strangest pieces of technology to come out of Japan in a while, which is quite a statement given their predilection towards bizarre inventions. These new batteries, somewhat aptly named NoPoPo, look tame enough, until you peer just a little bit closer. When the charge runs out, owners are encouraged to urinate on the batteries to juice ‘em up."
I would hate recharging these batteries. I certainly hope this is not a joke.
