I just read up on this for a few minutes and you guys are going way beyond what even the inventors are claiming. The farthest an air powered car has traveled is 7.2 km. The goal is 200 km.

You can't use an air motor to power a compressor that will compress enough air to sustain a constant speed. Think about it- that initial filled air tank has a certain amount of energy in it. Some of this is used to turn the motor, while some will be wasted (internal friction, for one). Then, some of THAT energy will be used to keep the car moving against air resistance and rolling resistance, while some will (in your plan) turn an alternator to generate electricity. Energy will be lost in the alternator, and energy will be lost once you run a compressor with it. Sure, you'd be able to compress some air with a scheme like this, but I really doubt it would significantly add to the range. The added weight would also reduce the benefit.

How can you say there is no way when you see the car actually moving
You believe everything you see on youtube? I can claim I'm using condensed strange quarks to power my car and push it down the street, then take video to prove it. Will you invest in my company, Quarkcars?
