New biofuel for cars: whiskey
A new whisky biofuel that can be used to power cars has been developed by scientists in Edinburgh.
Researchers found a formula to make the fuel from whisky by-products.
They 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 produce butanol.
This form of alcohol can then be used as fuel to drive a vehicle, much like ethanol.
