Robots of the future may be fueled by pee. Yes, pee.
Robotics engineers have constructed a new device that can pump human waste into the "engine room" of a self-sustaining mechanical system, which employs a team of live microorganisms to digest the organic matter, in the process generating electricity to power the machine.
A recent test of the system used microbial fuel cells, powered by urine
, to charge a mobile phone. (See video below.)
Future applications of the system, the researchers contend, could be used in the new generations of more advanced "EcoBots."
