Researchers have finally discovered a new source of green energy to power our mobile phones with- urine.
According to Bristol Robotics Laboratory's researchers, they were able to harness an electrical charge by passing urine through a stack of microbial cells that reacted to compounds, which include chloride, sodium and potassium, the Mirror reported.
AdvertisementThe charge was enough to help make a brief call on a Samsung phone, send a text message or browse the web.
Dr Ioannis Ieropoulos, from the University of the West of England, said that using the ultimate waste product to power things is as eco as it could get.
He said that making a call on a mobile phone takes up the most energy but the time will come where people would be able to charge a battery for longer periods.
The microbial fuel cells transform energy that turns organic matter directly into electricity via live micro-organisms' metabolism.
The electricity is a by-product of the microbes' natural life cycle - the more they eat, the more energy they generate and for longer periods of time.
The findings of the study have been published in the Royal Society of Chemistry journal reported.
