Researchers at Bristol Robotics Lab in the U.K. have developed a special machine, called “microbial fuel cell,” which converts urine into electricity that can be used to slowly charge smartphones or power small display screens.

The new “pee-to-power” invention comprises of electro-active bacteria that feed on the waste present in human free, releasing free electrons in the process, writes the BBC.

The machine, capable of producing about 30 to 40 milliwatts of power from only two liters of urine, could be a practical solution for creating clean and renewable energy in poorer countries, notes Entrepreneur
