Electricity from Onions

An American company has come up with an ingenious way to generate electricity from the humble onion. According to Reuters, the new system is being installed at Gills Onions, the largest fresh onion processor in the U.S.
The system works by collecting the peels of the onions which are usually wasted. This waste is acted upon by special bacteria which generate methane. The methane is diverted to fuel cells which generate electricity. The electricity generated is estimated to be sufficient to power 360 homes.
