Of course you can make a car that runs on compressed air. That is not the part the defies physics. I'm sorry, and I mean no personal offense, but you clearly just "want to believe", and so you believe. The claims made in this article are outrageous, and anyone looking at them with an open mind and a basic understanding of physics sees that in the first few sentences.
Like the husband who was caught with his mistress said to his wife: "Now who are you going to believe, me or you're lying eyes?"
I saw the car working quite nicely.
If you persist, at some point I'll have to ask you to smile when you say that, pardner.
"They can't defy physics if they are in production, can they?"
Remember the phrase 'your mileage may vary'?

I'm with you on that... what got me was the statement "The Series 34 CAT´s engines can be equipped with and run on dual energies - fossil fuels and compressed air - ..."
... and then I 'got it'. IT RUNS EFFECTIVELY BECAUSE IT REALLY IS JUST A SMALL GAS ENGINE AT HEART. The compressed air part is just a non-very-important add-on energy storage to help it make bogus environmental claims.
You are just being a nuisance and a heckler, Back up your objections, if you can.
