1. A power generation device comprising:
a first rotating body that converts energy of fluid into rotational motion;
a second rotating body that converts energy of fluid into rotational motion;
a differential device that is connected to the first rotating body via a first transmission path and to the second rotating body via a second transmission path, and that combines the rotational motion of the first rotating body and the rotational motion of the second rotating body and outputs the rotational motion; and
a generator that converts the rotational motion output from the differential device into electric energy, wherein:
the first rotating body and the second rotating body are arranged along a horizontal direction;
the differential device is positioned vertically above, in a vertical direction perpendicular to the horizontal direction of the first rotating body and the second rotating body;
the differential device faces the fluid via a weir that guides the fluid downward; and
the generator is located on an opposite side of the differential device from the weir.
