Generally the combination of booze and driving is discouraged, but not in the U.K.'s royal family. Prince Charles has
converted his vintage Aston Martin DB6 to run entirely on bioethanol fuel distilled from surplus British wine.
Use of wine-based ethanol is actually not such a bad idea, because while corn crops--America's primary biofuel source--suffer across the midwest due to difficult weather this growing season, British vineyards seem to thrive in the world's new slightly warmer climate.
While it won't reduce the prince's carbon footprint too dramatically as he only drives the car 200 to 300 miles a year, the transition to green is a nice gesture. Conversion of his private jets and helicopters to run on gourmet food items is still underway.
