A Cellphone Powered by Urine

urinals.jpg Cellular News reports that physicists in Singapore have developed a battery that can be powered by human urine for for those "emergency" phone calls when your conventional battery has died.

"Led by Dr Ki Bang Lee, a team at Singapore's Institute of Bioengineering and Nanotechnology developed the paper battery which is designed to be cheap to produce, and use urine as its power charge source.

Using 0.2 ml of urine, the team were able to generate a voltage of around 1.5 Volts with a corresponding maximum power of 1.5 mW. Battery performance can also be adjusted by using different construction materials.

The research was published in the Institute of Physics' Journal of Micromechanics and Microengineering."
