Two designers have created engines that can be run on a compressed air tank for a fraction of the energy cost of gasoline. The engines can be run on compressed air alone or a hybrid of compressed air and a motor to refill the air tank.
With a hybrid compressed air engine, one could travel from New York City to Los Angeles on a single tank of gas!
The first line of air-powered vehicles will be powered by compressed air alone; they will have a top speed of 110 km/h with a range of 210 km. The tanks can be refilled in 3 minutes at a compressed air station or plugged in and refilled with the on-board compressor.
