There's rich, and then there's royalty. Lest you confuse the two, consider the fact that Britain's Prince Charles now drives an Aston Martin DB6 fueled by white wine. To be fair, the Prince's Aston actually runs on bioethanol distilled from surplus wine. It turns out EU countries cannot sell more than a set quota of wine, so any excess must be destroyed or turned into something else; motor fuel, for instance. The prince, wanting to do his part for the environment, elected to have his Aston converted to run on the stuff, since its CO2 emissions are 85% lower than those of gasoline. Don't expect this concept to catch on over here in the colonies anytime soon as even the cheapest box of Franzia is still more expensive than a gallon of wine. For the moment anyway.
