That's not how the hyperloop works. The air isn't for moving, it's for reducing friction using the air hockey table effect. The acceleration is provided by linear induction motors in accelerator sections. It's that combination which results in a high speed train at low costs.
no, the hockey table thing is a convenient (but unnecessary) side effect.
Moving the air from front to back (with a pump) is needed to compensate for being in a partial vacuum rather than a true vacuum. Without the air pump you don't have a hyperloop. You just have a maglev in a tunnel.
I never implied that moving the air provided the motion.
