Australian Air-Powered Engine

An Australian man has invented a vehicle powered by compressed air, although it's not the world's first, despite his claims (I've seen other prototypes before). However, the best part of Angelo Di Pietro's design is that it tosses almost all of the moving parts traditionally associated with engines, instead leaving traditional pistons-in-cylinder designs for a rotary (don't know about its Wankelness, but there you go).

The test vehicle has reached 31MPH, too, so we're not talking a little joke vehicle, although they didn't mention how long a tank would power the little cart. I did notice that Di Pietro's company, EngineAir, also designs roots blowers. Perhaps we'll soon see the world's first forced induction compressed air engine?
