Peripherals/Body Fluid Power
Electric power using liquid as a catalyst can be produced with a special mixture of magnesium and carbon. Could liquids including beer, apple juice, cola, saliva and of course urine be used to run the XO?
 Urine Power
To make a urine powered battery a piece of paper is soaked in a solution of copper chloride and sandwiched between strips of magnesium and copper. This sandwich is then laminated between two sheets of transparent plastic.
When a drop of urine is added to the paper through a slit in the plastic, a chemical reaction takes place that produces electricity.
