WATER (WATER VAPOR) CIRCULATION TYPE COMBINED POWER GENERATING SYSTEM OR THE LIKE UNITING HYDRAULIC POWER GENERATION USING SEA BOTTOM (UNDERSEA) DAM OR THE LIKE, (SEAWATER OR THE LIKE-UTILIZING) GEOTHERMAL POWER GENERATION, OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To achieve a water (water vapor) circulation type combined power generation system using renewable energies (geothermal energy and the like) in combined manner.SOLUTION: A sea bottom dam power generation plant or the like in which hydraulic pipelines or the like with a head drop of about 500 to 1,000 m from a shallow (around a water level) are built in a pressure-proof manner (along an underwater continental slope), its drain channel is linked in a connected manner on a line extended obliquely downward up to a geothermal well (artificial storage tank or the like) placed under the ground of a depth of about 1,100 to 5,000 m (from the ground level), the depth being allowed to be excavated technically, and water (water vapor) for power generation and the like is circulated and utilized for power generation while a water flow rate through a water passage via a prescribed sea bottom dam or the like is increased in proportion to a tremendous amount of water vapor generated in the deep ground, the water (water vapor) for power generation corresponding the generated water vapor.
