‘Pee power’ as researchers turn urine into a sustainable power source for powering electronic devices

In the near future this device could provide a means of generating much needed electricity to remote areas at very little cost, each device costs just £1-£2. With growing global pressures to reduce reliance on fossil fuels and the associated greenhouse gas emissions, microbial fuel cells could be an exciting alternative. A microbial fuel cell is a device that uses natural biological processes of ‘electric’ bacteria to turn organic matter, such as urine, into electricity. These fuel cells are efficient and relatively cheap to run, and produce nearly zero waste compared to other methods of electricity generation. In practice, urine will pass through the microbial fuel cell for the reaction to happen. From here, electricity is generated by the bacteria which can then be stored or used to directly power electrical devices.”
