Wind-assisted propulsion is a method of using wind power to help propel vehicles, particularly ships. This technique involves the use of sails or other wind-capturing devices to harness the energy of the wind, reducing the reliance on traditional fuel sources. By capturing wind energy, vessels can improve their fuel efficiency and decrease greenhouse gas emissions. This approach is gaining popularity in the maritime industry as a sustainable alternative to conventional propulsion methods. Innovations in design, such as Flettner rotors and kite sails, are being explored to enhance the effectiveness of wind-assisted propulsion, making it a viable option for modern shipping.
