The U.K.'s 'Poo Bus' Is Becoming a Crappy Reality

In the U.K. it's becoming a civic duty to go doody, with a commuter bus sliding onto the roads that's powered by human waste.

The Bio-Bus will roll out of the garage on March 25 to service Bristol, its fuel tanks swollen with biomethane gas made from local sewage and food scraps. Though the vehicle was unveiled last year, this inaugural run provides a crucial sounding of public opinion. Its operator, First West of England, says it hopes to learn how the ride—known colloquially as the "poo bus"—"copes with the demand of a city-wide operation, and how the general public react to it."
