Smartphone batteries run down so quickly, but the power to recharge could lie within us literally. Ioannis Ieropoulos, an engineer from Bristol, has charged a mobile phone battery using urine.

You pee into a microbial fuel cell, or MFC for short. MFCs contain bacteria. When those bacteria feed on the pee they produce electrons. If we harvest those electrons, we can use them to charge a battery.

You can't buy urine-powered MFCs just yet, but Ioannis foresees a future of energy-making smart toilets. Bog-powered batteries, eh? Science, I salute you.
