re: #12 Buck

Save the environment is a great idea. I support that 100%. But it will take 20-40 years to replace all the cars with environment friendly choices.

In the meanwhile…

We could seriously reduce the strategic importance of oil if all vehicles sold in America were required to be able to run on any biofuel. Then the fuel mix would contain whatever mix of biofuels is the most economical. And OPEC’s power would virtually evaporate. It would cost $100/car and the technology already exists. We can do this today to reduce the importance of oil as a commodity.
