Ship system, ship, and rotating body

Abstract

To provide a ship system, a ship, and a rotating body that can be used efficiently.SOLUTION: A rotating body 50 for a ship can be used for the propulsion of a ship 1 and generates electricity by freely rotating during the travel of the ship 1. For this reason, the rotating body 50 for the ship can generate the propulsion force during the travel of the ship 1. On the other hand, free rotation can generate electricity at a timing such as sailing. Thus, the timing of use of the rotating body 50 for the ship can be expanded. Therefore, the rotating body 50 for the ship can be effectively used.SELECTED DRAWING: Figure 3
