Chrysler Turbine Car

The fourth-generation Chrysler turbine engine ran at up to 44,500 revolutions per minute, according to the owner’s manual, and could use diesel fuel, unleaded gasoline, kerosene, JP-4 jet fuel, and even vegetable oil. The engine would run on virtually anything and the President of Mexico tested this theory by running one of the first cars–successfully–on tequila.

We like to think of electric cars and hybrid cars and cars that run on alternative fuel as new concepts but there’s been people working on these technologies for a long time.
