The city of Oslo is getting down and dirty with a new scheme for its public transportation. Adding "minor modifications" to 80 of the city's public busses will allow them to run on biomethane fuel produced from raw sewage. The buses are apparently much quieter, and are more eco-friendly than biogas, with zero carbon emissions. The leader of the project, Ole Jakob Johansen, also says that the city should save about €.40 per liter on fueling the busses. The trial is part of Oslo's plan to be carbon-neutral by 2050, and they hope to soon have the entire fleet of 400 rolling clean. Waste not, want not, huh? [Via
