Whisky fuel could power cars
How about a whisky to go?
Scientists say they have developed bio fuel for cars from waste produced in distilling Scotch whisky.
Researchers at Edinburgh Napier University have produced a type of fuel called butanol using "pot ale" the liquid residue from copper stills and "draff," or leftover grain.
They say it can be used in ordinary cars without adapting the engines. And unlike some bio fuels, it is made from waste products and does not require a crop to be grown.
