Scientists at the Institute of Bioengineering and Nanotechnology have developed a prototype battery that runs on urine. One drop of urine applied to a paper soaked in copper chloride solution (sandwiched between copper and magnesium strips) which caused the prototype to function like an AA battery for 90 days. While recharging it might be a bit distasteful, at least it's biodegradable. [GT]
