Air Car
No, not a car that files.
A car that runs on compressed air. Now that is an innovation! It sounds too good to be true, but, according to this article on Wired News, the compressed air car actually exists. At the moment there are some issues with regulation and drive length, but, c’mon, this is the ultimate 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!
