Physicists in Singapore have developed a battery that can be powered by human urine. A team at Singapore's Institute of Bioengineering and Nanotechnology developed a paper battery which is designed to be cheap to produce, and use urine as its power charge source.
Imagine the uses: recharge your cellphone, mp3 player, digital camera and more just by pissing on them.
Recharge your hearing aid by having a friend piss in your ear.
During the Christmas season when you need batteries for your kids toys -- tell them to piss off!
Perhaps there'd be a new size battery - the P battery.
