Liquid Air Power & Automobile Co.

The Liquid Air car resembled any light steam buggy of the period, but carried a tank of liquid air under high pressure whose expansion was supposed to drive an ordinary single-cylinder steam-type engine. The efficiency of such a system was been estimated at only 4%, and it is improbable that the car could have run any distance, if at all. The scheme was probably a stock promotion project, like those of the Pennington and some other companies.[1]
