If you're a car geek like me, or just a geek in general, you should check out FutureCar on The Discovery Channel. Each episode deals with a different aspect of the future of the automobile. They discuss all kinds of insane theories that are being explored by the most industrious engineers and scientists. There's a guy named Guy (he's French so he pronounces it "Gee") who has developed a car that runs on compressed air. He says the next step is to develop an on-board air compressor so you'll never need to refill the tanks. I think he's forgotten a few inarguable laws of physics and energy with that last jump out of reality, but he's actually built a number of cars that run on air, an interesting and potentially promising move away from fossil fuels. A little "air" from my dog's back bumper area and we could fuel a second trip to the moon.

FutureCar is a four-part series that originally aired in February, but look out for rebroadcasts of this excellent project.
