Do you want to own a car that saves energy? Do you believe that cars can be powered by coffee? Now read the following passage to get the answer.,If youve ever wondered what people could do with those annoying used coffee grounds (渣滓), engineers in the UK have come up with an answer: use them as gas for your car! Engineer Martin Bacon and a group of volunteers from Teesdale Conservation in Durham, England, have been hard at work making those coffee grounds into something special: gas for a speedy coffeepowered car. The car ran entirely on coffee grounds and broke the world speed record for a car powered by organic waste. The coffee car, an adapted Rover SD1, averaged 66.5 mph, breaking the previous record of 47 mph achieved by a US. team which built a car fuelled by wood pellets (木质颗粒燃料),Engineer Martin Bacon, with his team, removed all the equipment from the old car and refitted it with an onboard wood gas generator (发动机) system, which turns waste coffee grounds into energy to drive the engine. Mr. Bacon said the car could run 100 miles on 10 kg of coffee grounds, collected from two local cafs. The car is not the first to be powered by coffee, though Mr. Bacon and his team based the design of the Rover on a white coffeepowered Volkswagen Scirocco built for the BBCs science show Bang Goes The Theory. That car was driven from London to Manchester in March 2010 and it now holds the Guinness World Record for the longest distance driven by a car powered by waste material.,Host of Bang Goes The Theory explained that the cars demonstrate an alternative (可能的选择) to powering engines using petrol. One day, when a strong cup of coffee wakes you up in the morning, you can use the coffee grounds to drive to work.
