A gas powered bus set new world record in a test which took place at Milbrook's proving ground in Bedfordshire, UK. The bus set a speed record at 76.785mph and reached a top speed of 80.78mph. Normally speed limited to 56mph, the bus was painted black and white like a Friesian cow because it runs on bio methane Compressed Natural Gas produced from cow manure. Its fuel is made from animal waste which is broken down in a process called anaerobic digestion to produce biogas, which is then liquefied and stored in seven tanks fixed inside the roof of the bus. The record bus was back in service the following day in Reading, a town in Bedfordshire.
