Air pressure engine

Hello, I noticed this link a few years ago and since then I don’t understand why it didn’t hit Blitz like this.http://www.youtube.com/watch?v=uVIwropRMME A car that only drives with air pressure and thus does not produce a Co2 and has less wear and tear, with a tank you get as I understand 200-400Km and I assume that a new filling should not last more than 10min. Is this the story with the money maker’s pond again? Will de r The state and the car industry do not want us to buy long-lasting cheap cars? or what do you think? I would also like to know: How much could a diesel or petrol engine be converted to air pressure? The Tüv would certainly make problme but why?
