Another veteran of the Today Show and the New York auto show (pictured) is Zero Pollution Motors' Compressed Air Car. The vehicle has achieved from 96 to 106 mpg in tests over an 850-mile course. It runs on cold air up to 35 mph. Then air is heated by a gas or electric heater to make it expand and give the car a boost.
