Wind-assisted propulsion is the practice of decreasing the fuel consumption of a merchant vessel through the use of sails or some other wind capture device. Sails used to be the primary means of propelling ships, but with the advent of the steam engine and the diesel engine, sails came to be used for recreational sailing only.
Marine steam reciprocating engines, ca. 1905 A wind propelled fishing boat in Mozambique. Until the application of the coal-fired steam engine to ships in the early 19th century, oars or the wind were the principal means of watercraft propulsion.
According to the Cousteau Society, "when compared to the thrust coefficient of the best sails ever built (Marconi or square types, i.e. ships of the American Cup [sic] or the Japanese wind propulsion system) that of the turbosail is 3.5 to 4 times superior and gives the system a unique advantage for the economical propulsion of ships."
“Existing wind ships suggest that wind propulsion is a sound investment for both the bottom line of shipping companies and for the planet.” For more CNN news and newsletters create an account ...
The wind-powered Pyxis Ocean cargo ship sailing in the English Channel in March 2024 (Cargill) ... could see half of new-build ships featuring wind propulsion by 2025, according to Mr Cooper.
A windmill ship, wind energy conversion system ship or wind energy harvester ship propels itself by use of a wind turbine to drive a propeller. They use wind power [1] through a mechanical or electrical transmission to the propeller. Where transmission is electric, storage batteries may also be used to allow power generated at one time to be ...
