An Air Car You Could See in 2009: ZPM’s 106 MPG Compressed-Air Hybrid : Gas 2.0

Compressed-Air Powered cars could take you over 800 miles on a single fill-up, at speeds of up to 96 mph. They should be refillable in less than 3 minutes, and at speeds over 35 mph emit about half the CO2 of a Toyota Prius. Oh yeah, and you could see them in the US at the end of next year.
