Pneumatic elevators are compact and ideally suited for places that are limited in space, for example, the spar of a SeaPod. Pneumatic elevators use vacuum and air to operate the car. They are eco-friendly that rest on an existing platform and do not requiring pre-construction shafts, pits or machine room to operate like conventional elevators. They consume lesser power than conventional elevators since they use vacuum to move up and gravity to move down.
