Researchers have developed a miniature fuel cell costing as little as £1 that can generate electricity from urine. The device, a microbial fuel cell, could be used to create a renewable and carbon-neutral way of generating power to remote areas at very little cost. Each of the fuel cells, developed by researchers at the University of Bath, Queen Mary University of London and the Bristol Bioenergy Centre, costs £1 to £2. Microbial fuel cells use natural biological processes of “electric” bacteria to turn organic matter, such as urine, into electricity. Urine passes through the microbial fuel cell for this reaction to happen, with the bacteria then generating electricity.
