I'm a little tired of hearing this environmental drivel coming from the far left. It is the same old tired argument. Detroit has the super secret blueprints for a car that runs on water, but they won't build it because they want to keep us dependent on foreign oil. The argument is years old, but greens have added the terrorism/despotism angle to try to make it an easier sell. I won't bother to try to debunk such a shallow argument, especially since I would be hard pressed to come up with something better than this.

What I will say is that consumer demand is what drives Detroit, not oil stocks. There is a lot of truth to the saying that 'necessity is the mother of invention.' When the need (or desire) is there, we'll come up with something. The fact that Detroit is already working on hybrid cars and SUVs is a case in point. As demand for the vehicles rise, so will the availability.

I'll also point out that even electric cars which need to be periodically charged are not pollution free. That electricity has to come from somewhere, and right now it's being produced with fossil fuels. You may sleep better at night driving your EV-1 Deathtrap, but you aren't really helping the environment much when all your electricity comes from that coal burning power plant 50 miles down the road.
