The land speed record for a regular bus has been shat on. "Bus Hound," powered by biomethane derived from cow manure, clocked 76.785mph in speed trials in England.
Operated by Reading Buses, the vehicle was painted black and white in honor of the Frisian cows whose excrement powers its mighty engines. It was designed to advance the "power and credibility of buses fuelled by cow poo," reports the BBC.
"Most importantly we wanted to get the image of bus transport away from being dirty, smelly, and slow," Chief engineer John Bickerton told them ."We're modern, fast, and at the cutting edge of innovation."
Ars Technica's Sebastian Anthony writes that biomethane is a promising technology, far greener than natural gas, but close in performance: "not only are you leaving those fossil fuels in the ground, you're also combusting methane that would've otherwise ended up as an atmospheric greenhouse gas."
If you're wondering, the answer is yes: Britain has also invented a bus powered by human excrement.
GENeco general manager Mohammed Saddiq said: "Gas-powered vehicles have an important role to play in improving air quality in UK cities but the Bio-Bus goes further than that and is actually powered by people living in the local area, including quite possibly those on the bus itself."
One human's annual output would would fuel the Bio-Bus for 37 miles. And if you're all out, there's always chip fat.
