No, it’s not a Mel Gibson joke… Scientists at Edinburgh Napier University have developed a formula for making butanol biofuel out of byproducts of the Scottish whiskey industry, reports Sky News. Apparently researchers
combined so-called pot ale – the liquid from the copper stills distillery equipment – and the spent grains used to make whisky, also known as draff
to create Butanol, an ethanol-like biofuel. Unlike the corn juice, however, Butanol can run in any gas-powered engine and does not degrade components over time.
