Original Note:
Although wind power is not new in ships, these sails do not work like the old sails used in the past. They're called wingsails, and they work like airplane wings instead. https://en.m.wikipedia.org/wiki/Wingsail The sails are not the primary means of propulsion, they're just a fuel-saving aid to the engines. https://yaramarine.com/windwings/
