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.
