The man who may or may not ever step up to the British throne has been keeping busy while his mother keeps his new seat warm. As wealthy people are wont to do, Britain's Prince Charles has a number of vehicles at his disposal. As a very public person, he has been trying to set an example by reducing the carbon footprint of his transportation fleet. Last year he had his Range Rover and Jaguar converted to run on biodiesel. Now he has decided to put some surplus British wine to use by having to distilled into ethanol to feed his Aston Martin. His Royal Highness has a 38 year old Aston Martin DB6 Volante that is now fueled by E100. The Aston only gets 8.3mpg (U.S.) on gas and will get less than that on ethanol. However, Charles only drives it about 300 miles a year so the overall effect is negligible at best. The vineyard that produces the wine is limited in how much it can bottle by EU quotas, so the leftovers are distilled to produce fuel.
