An improved method of lifting fluid using the difference between atmospheric or higher boosted pressure and fluid vapor or vacuum pressure applied to a series of chambers with a movable plate that divides each into variable volumes, and comprises one stage of the system. Combinations of pressures in the chambers between the movable plates lift the fluid to a height where the fluid column base pressure equals atmospheric or boosted pressure less friction and mass losses. A vertical array of stages, each lifting fluid from the stage below it, allows fluid to be lifted to any height, limited only by structure or geographic elevation. Further; operating pressures are tapped from the top and bottom of a standpipe filled with static fluid, pressure changes are made when the volumes are zero, and the sum of the volume receiving fluid and volume delivering the fluid are constant, making the system closed. Once raised, the fluid may be released for it's end use and more particularly; through a power generator. Where the fluid is water in an open environment and fed through a turbine, the water may be returned to the system reservoir to be reused in the cycle or if in a closed system the fluid may be returned to a chamber under pressure for reuse.

An air-driven generator for generating electric power from movement of a working fluid. Upper ends of buoyancy conduits are in fluidic communication with an upper end of a gravitational distribution conduit, and a lower end of the gravitational distribution conduit is in fluidic communication with lower ends of the buoyancy conduits. An air injection system injects air into the buoyancy conduits. A closed fluid loop is formed with working fluid flowing from the gravitational distribution conduit driving a fluid turbine system that is interposed between the lower ends of the gravitational distribution conduit and the buoyancy conduits. Flow of working fluid can be induced by an injection of air into working fluid disposed in the buoyancy conduits to achieve a generation of power by actuation of the fluid turbine system. An upper chamber can remove entrained air. A Rankin Cycle Generator can receive and be actuated by exhausted air.
