Officials say the garage that houses the Prince of Wale's biodiesel Range Rover will get a blanket of artificial turf. The insulation is needed to keep the car warm so the biodiesel fuel doesn't get thick and lumpy on cold nights. Apparently the Range Rover Prince Charles drives, or is driven in, runs on 100 percent biodiesel, no B5 or anything like that. Officials also say he may convert other vehicles in the future (his official Jaguar is already converted) and he is active in making the entire estate more energy efficient. One reason artificial turf was chosen is that it's made from recycled tires.
