  • the present invention relates to a floating vertical-axis turbine for offshore installation, for example, on a lake or sea.
  • the turbine of the present invention is to be known as the RingSailTM turbine.
  • a particular advantage of wind-generated and water-generated energy is in being a renewable energy source which generates no pollution.
  • Applications of energy so generated include driving electrical generators, pumps and compressors, such as used in desalinisation plant.
  • wind-generated and water-generated energy Another advantage of wind-generated and water-generated energy is that the energy can be generated locally at locations to which remotely-generated energy could not be easily transmitted, such as locations where no power line infrastructure exists. Examples of such locations include remote areas, such as offshore oil and gas rigs, where it would be uneconomic to install the necessary infrastructure, and on moving objects, such as ocean-going vessels, where permanent connection to a remote energy source would not be feasible.
  • a further drawback of existing wind turbines is the high noise level produced by those turbines.
  • the blade arrangement of those turbines is usually designed to maximize the revolution rate, resulting in a disturbing, audible noise level which varies in intensity and pitch with variations in the wind speed. Locating the wind turbines offshore would obviate this problem, but, as discussed hereinabove, the cost associated with installing existing wind turbines offshore is uneconomically high.
  • a yet further drawback of some existing wind turbines is the inability of those turbines to withstand high-speed winds, typically wind speeds greater than forty knots. Winds well in excess of forty knots occasionally occur in many areas of the world.
