Forget the tiger - put sheep urine in your tank
A
British bus company is testing a new secret weapon that it hopes will
help forward its push to cut its polluting emissions - sheep urine.
Stagecoach
has fitted a bus in Winchester with a tank containing the animal waste,
which is sprayed into exhaust fumes to reduce emissions of harmful
nitrous oxides.
Andrew
Dyer, managing director of Stagecoach South, said: "It is a novel way
of reducing pollution but we believe it will work. 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."
