Call it “The little engine that curd.” Students at Utah State University have broken a land speed record in a car fueled by the waste that remains from cheese making.

The student built car, known as the Aggie A-Salt Streamliner, was running on a student-derived biofuel made from yeast and cheese waste when it set the land speed record at 64.396 mph for a diesel-powered, one-liter, two-cylinder vehicle at the World of Speed event held at the Bonneville Salt Flats earlier this month.

It’s the first car in its class to break a land speed record while solely powered by biofuel. Previous records have been set by cars running on a mixture of biofuels and conventional diesel.

 The fuel was created by feeding the byproducts of cheese production to yeast, which yields a result that can be made into a biofuel that has a lower carbon footprint than conventional diesel. It’s one of three biofuels created in the lab of USU professor Lance Seefeldt, though only the cheese-based fuel was used at Bonneville.
