There are large losses with batteries, regenerative braking means maybe only a third of the energy gets back in to the battery. I'm sure air can do better there.

Also air is a little easier to dispose of enviromentally.

regardless of whether or not it's feasible air will never become the main stay. there would be no future in it for the likes of Shell or the other large fossil fuel companies. they will block any move manufacturers make.
