Urine powered battery developed in Singapore

And you thought it all ended with NEWater. According to British paper The Telegraph, a "paper battery that generates electricity from urine has been developed by scientists in Singapore to provide a new way to have a medical check-up." So nope, it doesn't mean that we're going to be asked to pee for our power anytime soon, as utlising "0.2ml of urine, [researcher] Dr [Ki Bang] Lee generated a voltage of around 1.5V with a corresponding maximum power of 1.5mW." Not quite enough to light up the Esplanade.
