Abstract
Abstract Method and system for generating electric power utilizing a coolant circuit, in which a coolant is evaporated at a lower level position, allowed to rise via tubing to a higher level position, liquified at the higher level position, and allowed to flow down to the lower level position in tubing where it impinges a hydraulic turbine connected to a generator. The preferred embodiment includes a vertical tube system of approximately 3000 m length, composed of a long tube for rising vapors and fall tubes for falling liquid coolant. Multiple cooling systems located at the higher level position, including a counterflow cooling system, forced-draught type air cooler, and a step-by-step cooling process, are utilized to liquify the coolant and provide working vapor to power the cooling systems. The coolant is composed to C 3 H 8 and NH 3 , which is varied on a percent composition basis to match atmospheric weather conditions.
