How The Magnus Effect Lets A Passenger Ship Harness Hybrid Energy From A Rotor Sail

Just like in sports the Magnus effect can be used for energy! The Finnish ferry MS Viking Grace is the first modern passenger ship to have a rotor-type sail (24m high) that allows, through the Magnus effect, hybrid propulsion. Propulsion like this was patented by the German engineer Anton Flettner in 1922. #cruiseship #greenenergy #cruise #viking #hybrid
