So no, you can't just fill your car with compressed air and drive off at 30mph, turning an alternator to power a compressor that compresses more air to keep you moving.

Of course it wont be able to just start from nothing that why it needs to have a tank full of air already this will start the motor and it can use the air from that tank to get the process started. How can you say there is no way when you see the car actually moving
