Bringing Rotor-Sails Back on Conventional Cargo Ships

An old German technology from the 1920s is now being revived both in the country of it's birth, as well as in Finland. I like the idea of rotor sails to supplement conventional propulsion and reduce fuel consumption, but cannot help wondering if this tech will be beaten in overall efficiency and costs by the Dyna-Rig.
