It sounds like the sort of idea a small child would have: if coffee makes you more energetic, why not put it in the gas tank too?
But British engineer Martin Bacon and a group of volunteer helpers have put the idea into practice, and managed to break the Guinness World Record for vehicles run on gas from organic waste.
The Coffee Car runs on used coffee grounds from cafes and restaurants.
And, in the test, it hit 77.5 miles per hour, with an average speed of 66.5mph, way ahead of the existing record-holder’s 44.7mph.
“Our first run up the track was 75mph, then the second run down into the wind was 58mph, giving us 66.5mph,” says the team.
Last year, the car won another Guiness World Record for the longest journey travelled by a coffee-powered car – although we suspect there may not have been all that much competition.
The car’s based on a Rover Sd1 straight 6 cylinder, equipped with a special gasifier designed to maximise output for a large engine. Some of the gas is compressed to 150PSI and injected directly into the manifold to get as high a speed as possible.
“The reason behind doing a land speed record is to show that the old technology of gasification, in its day renowned for being very slow, with a little bit of tinkering can be disproved and reveal the true capability and power of the gasifier,” says the team.
They say they’re looking for a sponsor for future projects.
