" From: John McEwen <moparrr@xxxxxxx> " " What you are overlooking is the tremendous number of products which " are made from petroleum in all of its forms. The petrochemical " industry is huge and burning the raw material or one of its refined " forms is not part of it. Ethylene is one of the major products and " is used in the chemical and plastics industries in many forms. " " Just to name two products should give you an idea of the scope " involved. They are ethylene glycol or antifreeze and polyethylene " the venerable plastic used everywhere for so many things that I " wonder if we could count them all. " " Burning petroleum and natural gas is not the most important usage for " the raw material. We have already developed technology to use other " products for transportation power. The major problem is that they " don't work as efficiently or simply as what we have today in the " gasoline-fueled, internal combustion engine. ethylene is a -major- chemical feedstock, and it's possible to make it from ethanol. the reaction usually goes the other way though, as - at present - it's often cheaper to make ethanol from petroleum [for non-food purposes] than ferment and distill it. i still think biodiesel has the most promise of the various alternative fuels. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
