Amazing - a car that runs on compressed air. Too bad it's really freakin ugly. Makes me think: What if you combined a solar panel with an air compressing machine? Could you have a car that refills while it drives? Could you develop a system that would generate enough compressed air to run the car in the city, thus providing an entirely sustainabile vehicle? It'd work great for city living.
