As it turns out, contrary to the initial reactions of a lot of people on the net, the cup is in fact perhaps not half empty after all.
The think I find most interesting in my travels around the web checking out information on the Mini-CAT is how much negative reaction I see from commenters. These are not in the way of valid criticism of the technology for the most part, but rather on a more emotional, knee-jerk "if man were meant to fly" tone. It sort of makes me feel a bit for Orval and Wilbur (up until they got their "ungodly" contraption off the ground).
From what I can see, the idea looks pretty good still. Take a moment to check out The official Mini-CAT website and The Mini-CAT YouTube site to see what is already being done (by people who are not Americans, to our shame) using existing technology to make people oil free.
Then take a look at these two videos.
The first one is where I first heard about the car.
The second is from Australian TV showing both the Mini-CAT and another compressed air car that is quite interesting.
If you find this sort of thing hopeful agitate your representatives to put some of our tax dollars into this kind of research.
My guess is that if we put the kind of effort into freeing ourselves from fossil fuels that we did into getting into space we would have it done in about ten years.
