Gotta pee? In the future, you might think twice before you flush that valuable power source down an ordinary drain. Scientists at Bristol Robotics Laboratory in the U.K. figured out a new way to make pee pee powerful enough to charge a smartphone.
How does it work? The magic occurs after urine (and other organic matter) passes through a series of microbial fuel cells, which contain tiny microbes that consume and metabolize the liquid into small amounts of energy. The Bristol-based scientists made a system that transfers the collected energy into a capacitor, and in this case, that pee power ended up giving a small charge directly to a Samsung smartphone.… Read more
