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. In recent years ...
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.
While the design is meant to be usable for different types of ships and even retrofitted to existing vessels, [7] the first vessel from the Oceanbird concept is planned to be a 200 m (660 ft) long roll-on/roll-off ship with a capacity of up to 7,000 cars. Such ships are optimized for transatlantic routes. The first vessel based on the concept ...
A Cargill-chartered cargo ship fitted with giant, steel sails has set out on its maiden voyage. Wind-powered cargo ship sets sail in a move to make shipping greener Skip to main content
Oceanbird is a wind-powered cargo ship concept, expected to cut emissions by 90%. The ship uses 80-meter-tall rigs instead of traditional sails and can cross the Atlantic Ocean in twelve days. The ...
According to Gavin Allwright, secretary general of the International Windship Association, a non-profit group promoting maritime wind propulsion solutions, there are currently 31 large (over 400 ...
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."
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 ...
