Wired News has a short article discussing a new company founded by Willie Nelson, which markets biodiesel, which is made from "vegetable oils, mainly soybeans, and can be burned without modification to diesel engines." As any diesel vehicle can use biodiesel without any modifications, it isn't hard for a truck driver (or say, someone driving a black VW Jetta) to switch over. Especially as the price per gallon is competitive with standard diesel prices - the article lists $1.69/gallon.This is an ideal crossroads for Willie Nelson, as it could ease dependence on foreign oil, lessen the environmental impact of oil drilling and help out the nation's farmers. Good stuff.
