Abstract: A wind energy installation having a tower, a gondola supported by the tower, a rotor mounted in the gondola, and at least one pressure pump that is mechanically driven by said rotor and that feeds a raw water-treating reverse osmosis plant, the components of said reverse osmosis plant being arranged within the tower.

Abstract: Method for operating a wind power plant provided with a rotor speed regulating device and involving the corresponding steps:

Abstract: Device for preventing the penetration of corrosively acting salt particles into the generator and gear area of an offshore wind power plant, with an air pressure generator for introducing air under an overpressure into at least a substantially closed part of the generator and gear area, and a filtering device connected upstream of the generator and gear area in the flow direction for the separation of moisture and salt particles from the air to be introduced into the area by the air pressure generator.

Abstract: A method for laying electrical cables from a first offshore wind power plant to a second offshore wind power plant. The method comprises placing the cable to be laid in the tower or the foundation of the first offshore wind power plant before the plant is erected, erection of the first offshore wind power plant, taking a tow line from one wind power plant to the other wind power plant, and drawing the leading end of the cable from the first wind power plant to the second wind power plant while releasing the cable from the tower or the foundation component of the first wind power plant.
