To resolve a temperature stratification by circulating a surface layer water and a deep water at closed waters without generating environmental load.
This system comprises: a low boiling point medium power generation system 12 which is arranged inside a floating structural body 2 provided within the closed waters, and circulates a low boiling medium having a boiling point lower than water, to generate power using temperature difference between the surface layer water and the deep water at the closed water; and a surface layer water intake pump 10 and a deep water intake pump 9 which are driven by the power, respectively supply the surface layer water 18 or the deep water 19 to the low boiling point medium power generation system 12, and perform flow back of the surface layer water or the deep water to the closed waters.
