I am not a coffee drinker and don't really want to be. But this car makes me want to steal the coffee grinds from the coffee machine at the end of the day and start storing this black gold. A team at the BBC1 science show Bang Goes The Theory got their hands on an old classic, a 88 Volkswagen Scirocco and made it run off of coffee grounds. That almost makes the Prius look bad for the environment.
Before you get excited and start converting your car to a coffee guzzler, consider this, it takes the equivalent of 56 espressos to travel 1 mile. Not exactly efficient or cost effective at the moment, but give it time. Gasoline's days are numbered.
