Pee Battery

Besides being a great and invigorating morning tonic, your urine can now be used to power electronic devices. 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. If only my bed was urine powered. I could fly to the moon! [Thanks, Karl!]
