POWER GENERATION DEVICE UTILIZING RENEWABLE NATURAL ENERGY

The present invention makes it possible to compensate for the drawback of renewable natural energy and generate high-output, high-efficiency, and stable power consumption. Power with zero fuel consumption generated from renewable natural energy (1) is temporarily stored in a storage battery (3), while a motor (M) exclusively for a power generation device is driven using power outputted from the storage battery, a plurality of generators (G1, G2, G3) are rotated via a rotational motion of the motor, and the output of one generator (G1) thereamong is charged to the storage battery (3) exclusively for the power generation device. The outputs of the remaining generators (G2, G3) are system-connected to an electric power company at prices under a feed-in tariff system. Incidentally, a coil (12) of the generator is formed into such a concave shape that envelops a permanent magnet (14), caulked, and rotated in a groove of the concave shape so as to face both side surfaces of the permanent magnet.
