Taking a ride on the sheep urine express:-

A British bus company believes it may have a secret weapon to cut pollution emissions -- sheep urine in the engine.

The Stagecoach company has fitted a bus in Winchester with a tank of sheep urine. The waste is sprayed into exhaust fumes to reduce emissions of harmful nitrous oxides, The Guardian reported Friday.

It is a novel way of reducing pollution but we believe it will work, Andrew Dyer, managing director of Stagecoach South, said. There is nothing to worry about -- we won't be asking passengers to leave a sample and we won't be carrying a resident sheep at the back of the bus.

The bus carried its first passengers last month.
