Driving on air

First we had flying cars now this. To answer all those calls for stories on alternative fuels we dug up this innovation. In Melbourne, Australia an inventor claims to have created a motor powered by compressed air. The story is pretty light on the workings of said the motor has only two moving parts and uses a rotary design. Supposedly a test vehicle has reached 31 mph. Even if the compressed air couldn't move beyond golf carts and tractors that alone would cut fuel consumption tremendously.
