Power of PEE

Singapore’s Institute of Bioengineering, in an effort to make everything as clean as possible, is working on a urine-powered biobattery. When a drop of urine is added to the copper chloride paper, a chemical reaction takes place and produces electricity, which is harnessed by the battery. A few drops will generate about 1.5 volts, the same as a AA battery. The battery needs to be developed further to make it commercially viable.The devices will be used in medical testing systems which can be powered by and test the same liquid stream simultaneously. So, next time when ur mobile battery is down, just take a leak.
