The Pee Power urinal will return to the Glastonbury Festival for a third year, with the project's biggest ever energy-generation system.
A new 40-person Pee Power urinal will turn an estimated 1,000 litres of urine per day into electricity to charge ten information panels, showing festival updates and other useful info in a prime spot near the Pyramid Stage.
A second unit, located near the press enclave and performers' area, will feature mobile phone charging and internal lighting.
Pee Power – developed by scientists at the Bristol Bioenergy Centre (BBiC) at the University of the West of England and funded by the Bill and Melinda Gates Foundation – uses microbial fuel cells that turn any organic waste into electricity. This year the team will undertake the first overseas Pee Power trial in Uganda.
"The Pee Power at Glastonbury project is the result of our close collaboration with our partners Oxfam and Dunster House and our collective effort to improve lives in refugee camps and areas of the world with no sanitation or electricity," comments Professor Ioannis Ieropoulos, Director of the BBiC.
"This fits well with the charities and organisations that have traditionally received support from the Glastonbury Festival over the years."
