A team from the BBC1 science programme Bang Goes the Theory has unveiled a car that runs on coffee. Christened as Car-puccino, the car is actually a modified version of a £400, 1988 Volkswagen Scirocco. Well, the visible area of concern, for millions like me, is the running cost of the vehicle that has been estimated at between 25 and 50 times the cost of running a car on petrol.
