Chungpin Hovering Liao, a professor at the Graduate School of Electro-Optic and Material Science of National Formosa University in central Taiwan, has developed the world’s first chlorophyll organic battery that can use any liquid, including urine, to produce electricity. The battery is completely non-toxic and starts to generate power within 10 seconds after being soaked or immersed in liquid. And any liquid will work; water, beer, soda, even urine.

The model Liao has can produce electricity for between 2-7 days right now, and it only puts out half as much power as a regular battery of similar size. Plus, it’s only a tiny sized battery, not an automotive sized one, but things can change. Liao has said that mass producing his batteries could be done for anywhere betwee 3 to 6 cents each.

Since technology advances in a parabolic curve, one day, we may all have dry backup batteries for our electric cars that you just pee on to activate. Pee-powered backup batteries… ahhh the future.
