A group of researchers at the University of Bath, in Great Britain have developed a urine-powered miniature fuel cell that's already capable of recharging a smartphone.
The device is just 25 square millimetres and uses a carbon catalyst created from the protein commonly found in an egg white – in other words, biomass. The urine passes through it and thanks to the ‘electric' bacteria present in the substance, electricity is generated that can be sent to a battery for storage or used to directly power an electrical device.
