The Cousteau Society built a ship using a somewhat similar idea back in the '90s, but AFAIK no one else has taken up the idea, so I assume there are practical problems: https://en.wikipedia.org/wiki/Turbosail
There's some nice video from the '20s.The Flettner Rotor Supply, Install and Commission Project will deliver a full scale demonstrator of Flettner Rotor technology on a large ocean going vessel which the ETI intends to source for the demonstration phase. Flettner rotors use a spinning cylinder to convert the force of the wind into thrust that helps propel the ship. . . .
