Pee Powered Batteries!

Now, in Japan, AA and AAA batteries can be purchased that are powered by certain liquids including water and urine. I don't think I really like the name of the brand, "NoPoPo", it just kind of sounds gross. Gross even for pee powered batteries. All of this means, now, you can finally recharge your batteries by peeing on them, kind of. A pipette is used to insert the liquid into a chamber in the battery. Using water may be the more hygienic option.

I think Nintendo needs to get on this ASAP and market this technology for the Wii controllers. There are some pretty good marketing opportunities there.
