Just an observation of what I saw in Brazil...There are many local ethanol refineries spread throughout the country side. They are small compact units. I realize it is sugar cane, but same thing could apply here. Transportation costs would reduce as more refineries are built. It also reduces the exposure to terrorist attacks on one large refinery concentration such as Houston, TX. It also reduces the exposure to weather related catastrophies (like hurricanes, etc...)

Excellent points.

Brazil only uses biodesiel for 20% of their fuel, and someone said they have about a 10,000 dollar tax on cars per year. It would take almost all our farmland in the US to convert to Biodeseil. Its not worth it.

Popular science claimed at 10 cents a KWatt*hour an electric car only costs 2 cents a mile for propulsion. So I say we fund the hell out of batteries and capacitor research and build dozens of new nuclear power plants. 100% clean fuel, no impact on the environment, and cheap.
