Poo-powered bus sets speed record

Cow manure – something New Zealand has in excess – has been used in the UK to power a commuter bus up to a record speed of 123km/h. While most standard buses max out at around 90km/h, the Bus Hound – operated by Reading Buses, and decorated in a Friesian-style black and white – set the record for a regular service bus on a race track using gas made from cow dung that had been brewed in an anaerobic digester.

Cow effluent is currently a major problem for New Zealand waterways, and has led to the degradation of most of our lowland rivers.
