The UK’s poop-powered bus has set a speed record for a regular service bus with a top speed of 76.8 miles per hour (123.5kph). The vehicle is called the ‘Bus Hound’ (a tongue-in-cheek homage to supersonic Bloodhound SSC) and it’s powered by biomethane derived from cow manure. Operated by Reading Buses, the Bus Hound is decorated with a black and white skin reminiscent of the Friesian cows used for milk production around Britain, and it’s said to sound like a Vulcan bomber.

The ‘Bus Hound’ has broken the land speed record for a regular service bus as it was being tested at Millbrook Proving Ground in Bedfordshire. This is a great achievement as its oil-eating counterparts typically max out only 56 miles per hour.

The innovative vehicle runs on biomethane produced by the anaerobic digestion of cow poo in a bioreactor. After the methane is compressed and liquified it is stored in a series of tanks fixed to the inside of the bus’s roof.

Chief engineer John Bickerton told the BBC ‘It was an impressive sight as it swept by on the track,’ ‘It sounded like a Vulcan bomber.’
