Abstract
A lifting platform is disclosed that utilizes means for energy recovery in order to maximize efficiency. Prior lifting platforms described by the inventor have utilized partial toroidal vortices in order to create a high pressure region below the platform. The present invention, however, improves on the prior lifting platforms by utilizing a complete toroidal vortex. Thus, a great deal of the energy expended is recovered by the recirculation of the fluid. The vortex fan must only supply the energy needed to overcome friction.
