Proving that coffee truly is the solution to all of the world’s problems (ok, so not really), a team of crazy Brits has modified a VW Scirocco to be powered by coffee! Well, not entirely. You see, it uses a charcoal fire to heat the coffee grounds, splitting them into carbon monoxide and hydrogen gas. The hydrogen gas is then burned in the engine to propel the car. Hardly efficient nor eco-friendly but hey, it’s still a coffee-powered car!
