Prince Charles' Latest Eco-Friendly Car Runs On Surplus Wine

London, UK (AHN) - Aside from several Jaguars, an Audi and a Range Rover that run on used cooking oil-based biodiesel, an Aston Martin fueled by bioethanol from wine is the latest environmentally friendly car of Britain's Prince Charles.

The luxury car given by Queen Elizabeth as a birthday present when the prince turned 21 has been converted to run on pure bioethanol supplied by Green Fuels Limited. The biofuel is made from excess local vintage produced by English wine makers. The wine comes from a vineyard close to Prince Charles' Highgrove Estate, a spokesman of Green Fuels told CNN.com.

Prince Charles, 59, has been using biofuel for his cars and the royal train to reduce his carbon emissions during travel, according to his office.
