A new whisky biofuel that can be used to power cars has been developed by scientists in Edinburgh.
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. However, the Scottish scientists said butanol was superior to ethanol with 25% more energy per unit volume.
I’m sure we can get used to looking for 101 proof instead of 91 octane.
