Scientists in Scotland were able to build a car that runs on leftovers from the whiskey distillation process.
They retooled the motor of a Ford Focus to run on biobutanol, which is made from a combination of the barley residue left after whiskey is fermented and pot ale, another leftover chemical created when whiskey is distilled.
This was a big breakthrough because only 10% of what flows out of any distillery actually becomes whiskey. The other 90% is waste — unless it’s turned into fuel, which actually burns cleaner than gasoline.
