Floating generation apparatus

Disclosed is a floating type power generation apparatus. The power generation apparatus includes: a hull capable of floating on water; a rotation body which is arranged inside the hull, with the ability to rotate, and which has a sphere shape or a hemisphere shape; a plurality of permanent magnets arranged on the surface of the rotation body with alternating north and south poles; and more than one coil arranged on the hull. Therefore, when the hull is floating on water and the rotation body is rotating, an electromotive force is generated from more than one coil. Furthermore, the power generation apparatus includes a charging unit connected to the coil, a pendulum element connected to the rotation body, and a sail element arranged on the hull.
