A car that runs on compressed air -- and it's real. The BBC by way of Cliff Schecter (with video):
The air car, also known as the Mini-CAT or City Cat, can be refueled in minutes from an air compressor at specially equipped gas stations and can go 200 km on a 1.5 euro fill-up -- roughly 125 miles for $3. The top speed will be almost 70 mph and the cost of the vehicle as low as $7000.
Which incompetent Detroit asshat will try to kill it or ban it from use in the United States? Will it be GM? Will it be Ford, whose stock price is at a pathetic $6/share? Or will it be the agri-businesses in the midwest who are betting on ethanol?
