The Alcyone - an experimental turbosail boat operated by the Cousteau Society. Turbosails work on the Magnus effect: An object spinning in fluid (or air) creates a whirlpool that results in a force perpendicular to the stream around the object: This exact effect is responsible for the curved trajectory of spinning footballs or golf balls. Turbosails - as a supplementary propulsion to diesel engines - improve the fuel efficiency of the vessel by 15-30%. View Larger
