Robert Zubrin had a pre-holiday op-ed over in the Washington Times that’s worth a read:

Let the market decide – oil, ethanol or methanol
Ladies and gentlemen of the left and the right: Let’s be realistic. There is no chance whatsoever that the U.S. political system will either: A) Pass carbon or gas taxes sufficiently punitive to compel Americans to curtail their driving substantially, or B) Support rapid expansion of offshore drilling for the foreseeable future.
Therefore, if neither conservation nor production is in the cards, how can we hope to deal with our nation’s dangerous and ever-growing dependence on foreign oil?
Here’s my answer: We need to cure our cars of their oil addiction. To paraphrase Shakespeare, the fault is not in ourselves, but in our cars; we are made underlings.
Let’s stop the guilt-ridden breast-beating and place the blame where it belongs. We are not addicted to oil. Our cars are addicted to oil. They are like a tribe of people who, because of some unfortunate flaw, can only eat one kind of food, say herring. Thus, if the herring merchants combine to rig up the price of their product to $100 per pound, the tribesmen have no choice but to submit. They would be far better off if they could become omnivores, capable of eating steak, ice cream, corn, eggs, apples, etc., as the power to use such alternatives would make them immune from herring-cartel extortion.
Our four-wheeled servants have the same problem; they can only drink one kind of fuel. Unfortunately, because we are the ones who must foot the bill for their singular habit, their problem is our problem. We need to cure them.
Fortunately, such a cure is at hand. The technology exists to make cars that are fully flex-fueled, able to run equally well on gasoline, ethanol or methanol, in any combination. If installed at the time of manufacture, the inclusion of this feature adds only about $100 to the cost of a typical car. The benefits of making such a childhood immunization against oil addiction a standard requirement for all new autos sold in the U.S. would be profound.

The rest here.
