Abstract
An electric power generation system includes a wind turbine, a conductor rotating as the wind turbine rotates, a heat transfer medium vessel, a magnetic field generator, a heat accumulator, and an electric power generation unit. The magnetic field generator is operated to generate a magnetic field and therein the conductor is rotated and thus heated through induction, and the conductor's heat is transmitted to the water in the heat transfer medium vessel to generate steam which is in turn supplied to a steam turbine and thus drives an electric power generator to generate electric power.
