No, not a car that files.

A car that runs on compressed air. Now <b>that</b> is an innovation! It sounds too good to be true, but, according to <a target="_blank" href="http://www.wired.com/news/autotech/0,2554,60427,00.html">this article on Wired News</a>, the compressed air car actually exists. At the moment there are some issues with regulation and drive length, but, c'mon, this is the <b><i>ultimate</i></b> green car. I mean, what's the down-side to this? Air might leak out? And, we could even use solar power to run the air-compressor to "re-fuel". I love this car. Now, if they can just get a model that runs further than 5 miles on a tank of air and get the US government to approve it....
Ah, well, a guy can dream!
