The researchers have produced a type of fuel from distilled Scotch whisky, from Diageo's Glenkinchie Distillery.
The fuel uses "pot ale" — the liquid deposit from copper stills — and "draff" or leftover grain. Scientists claim it can be used in ordinary cars without altering the engines. Observers say the whisky bio-fuel has "earned a toast" from ecologists.
Supporters of the bio-fuel resulting from whisky byproducts say it could offer a new supply of revenue for one of Scotland's biggest industries, as well as helping to ease reliance on foreign oil.
