Power generation system

Abstract

There is provided a power generation device that generates electricity using a potential energy of a circulation fluid (F) raised to a predetermined height position by a wave force, the device including: a float (27) that includes a hollow portion (27A); a feeding device (24), the feeding device (24) being accommodated in the hollow portion (27A) of the float (27); and a power generation unit (23) that generates the electricity using the potential energy of the circulation fluid F raised to the predetermined height position, wherein a lower portion of the float (27) protrudes such that a cross-sectional area in a horizontal direction decreases as the floating body extends downward, the device further including a storage tank-side accommodation portion (2) that accommodates the float (27), the feeding device (24) and the power generation unit (23).
