| Dr. Ioannis Ieropoulos, a scientist at the University of Bristol in England, says he used such a generator to charge a widely available smart phone with enough power to enable SMS messaging, perform web browsing and make a brief call.
“We are very excited as this is a world first,” he said. “No one has harnessed power from urine to do this so it's an exciting discovery. Using the ultimate waste product as a source of power to produce electricity is about as eco as it gets.”
The power is generated by urine passing through what scientists call microbial fuel cells (MFCs). Inside the cells, microorganisms metabolize the urine and produce electricity in the process. The electricity output from MFCs is relatively small.
An added benefit, according to the scientists, is that what’s left of the urine is purified and can be released into the environment without having to go through a waste treatment plant.
