Artificial hearts could pump urine in order to power robots

A team at the University of Bristol has created and EcoBot that is power by a microbial fuel cell. The fuel cell contains microorganisms that digest urine and generate electrons which are then harvested to produce an electrical current. 

There’s a new use for artificial hearts, and it involves a more taboo bodily fluid than blood. A device that mimics the squeezing action of the human heart has been used to pump urine into a microbial fuel cell, which could power robots that convert the waste into electricity.
