From the article: "Instead of those tiny, tiny explosions of gasoline and oxygen pushing the pistons up and down, like in a normal internal combustion engine, the all-aluminum four-cylinder air engine used compressed air for the job.
"A hybrid version, using a small gasoline engine to power an onboard compressor for a constant supply of compressed air, is claimed to be able to travel from Los Angeles to New York on just one tank of gas."
A similar vehicle developed by Energine Corporation (South Korea) is mentioned, whose design supplants an electric battery for the small gas motor in powering the air compressor. The battery is also used to power the vehicle once it has reached cruising speed."
