  • Power generation device
    Patent number: 12241444
    Abstract: The power generation device disclosed in the present specification includes a first rotating body, a second rotating body, a differential device, and a generator. The first rotating body and the second rotating body convert energy of the fluid into rotational motion. The differential device is connected to the first rotating body via a first transmission path, and is connected to the second rotating body via a second transmission path, and combines and outputs the rotational motion of the first rotating body and the rotational motion of the second rotating body. The generator converts rotational motion output from the differential device into electrical energy. The first rotating body and the second rotating body are arranged along the first direction. The differential device is disposed offset from the first rotating body and the second rotating body in a second direction perpendicular to the first direction.
