No beans about it: An automobile dubbed the “Car-puccino” has been designed to run only on leftover coffee grinds. The heavily-modified 1988 Volkswagen Scirocco was created for British TV show Bang Goes The Theory , a program that’s all about “putting science to the test.” To prove that just about anything can be turned into car fuel these days, Bang Goes The Theory will drive the Car-puccino 210 miles from London to Manchester using only residual coffee grounds as fuel.
This coffee-guzzling car combines Back to the Future styling (the Scirocco was picked because it was cheap and it resembles the DeLorean) and steampunk aesthetics (with a radiator grill on the roof), and achieves 1.4 miles per pound of java, or about 56 espressos per mile. Driving between London and Manchester will require over 150 pounds of grinds, plus stops every 30 to 45 miles to refill, as well as frequent breaks to clean the coffee filtering system.
