To make the battery, Lee and his colleagues soaked a piece of paper in a solution of copper chloride and sandwiched it between strips of magnesium and copper. This sandwich was 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.

Now all we need is a pee powered car that way you dont need to step out of the car ...(although someone at NASA already had the idea)
