'Bio-Bus' powered by human waste makes its maiden voyage.
Britain's first bus powered by human waste has taken to the streets.
The 40-seater 'Bio-Bus' is fuelled by biomethane gas, generated by the treatment of sewage and food waste at a processing plant in the south west.
What's more, a solitary tank of the gas - delivered utilizing the regular yearly misuse of only five individuals - is sufficient to control the vehicle for 190 miles (305km).
