I mentioned in another comment that there are a couple different designs for levitation and all of them do not need a compressor system anymore. Even the air bearings can rely on on-board tanks of compressed air (even at full scale). The compressor is too expensive to implement and would require high power which isn't feasible since it adds cost and weight to the batteries.
