The power plant disclosed is an engine that derives its usefulness in the pursuit of energy generation by utilizing hydrostatic pressure differentials found or created in various liquids, gases or solutions, such as but not limited to water and air. It is generally provided as a configuration designed to create a pressure differential, and to use the pressure differential to increase the effective head seen via a penstock and turbine system. Pump systems that are employed include venturi systems, jet pump systems and other comparable mixed-pressure vacuum pumps. Multiple power generating systems are interconnected to provide continuous and constant power generation through a penstock and turbine system.
