摘要： The present invention relates to a wind turbine system for storage of wind energy, the wind turbine system comprising a tower structure (10) having one or more wind rotors (40) with at least one wind blade (50), such as at least two or three wind blades, one or more generators for converting wind energy to electrical energy, optionally one or more gearboxes, one or more air compressors, and one or more pressure vessels (65,90) being adapted for containing potential energy generated during periods when excess electrical energy is produced and configured to release energy during periods when inadequate electrical energy is produced. The one or more pressure vessels (65) may be a part of the tower structure (10) of the wind turbine system and configured to release compressed air for operating the one or more generators during periods of less optimal ambient wind conditions, such as periods of low or very low ambient wind speed. Further, the one or more pressure vessels (65) may be part of the tower structure (10) of the wind turbine system and configured to release compressed air for operating the at least one wind blade (50), such as the at least two or three wind blades, during periods of less optimal ambient wind conditions, such as periods of low or very low ambient wind speed. Finally, the one or more pressure vessels (90) may be separate from the tower structure (10) of the wind turbine system and configured to release compressed air for operating the at least one wind blade (50), such as the at least two or three wind blades, during periods of less optimal ambient wind conditions, such as periods of low or very low ambient wind speed.

摘要： The present invention relates to a vertical-axis wind turbine for increased generation of wind energy, the wind turbine (10) comprising a housing (15) having a front area (17) operable to receive ambient wind for generation of wind energy, a back area (19) operable to point away from the ambient wind direction, a bottom area (21) adapted to be fastened to a solid support (23), a top area (25) positioned in a certain height from the bottom area (21), and side areas (27,29) with one or more openings (33) operable to expel excess wind from the housing (15). The housing (15) comprises one or more wind rotors (40) extending substantially from the bottom to the top of the housing (15) having vertical axes relative to the ground and each comprising at least one wind blade (50), such as at least two or three, the one or more wind rotors (40) being operable to receive wind from the front area (17) of the housing (15) and expel excess wind through the side areas (27,29); and at least two wind guiding members (55), such as at least three or four, for each of the one or more wind rotors (40) adapted to capture and guide ambient wind from outer positions within the front area (17) of the housing (15) to each of the one or more wind rotors (40), enabling the one or more wind rotors (40) to rotate with an increased speed and/or invoking increased wind force on the one or more wind rotors (40). Further, the wind turbine (10) comprises one or more adjustable extensions (60,61) on each side of the housing (15), extending substantially from the bottom to the top of the housing (15), wherein said extensions (60,61) are operable to generate a higher pressure at the front (66) of said extensions (60,61) relative to the back (68) of said extensions (60,61) during operation, thereby generating a pressure difference between the front area (17) and the back area (19) of the housing (15) enabling the one or more wind rotors (40) to rotate with a pressure driven increased speed and/or invoking a pressure driven increased wind force on the one or more wind rotors (40).

摘要： A system and method for improving efficiency of vertical axis wind turbines for all wind directions, comprising (a) an inlet convergent section, (b) a wind turbine section adjacent to exit of convergent section and (c) an outlet divergent section. The system provides an air passage through the inlet section, the wind turbine and the outlet section, and allows for variation of the inlet and outlet depending on wind direction, in order to maximize efficiency harnessed within a time interval in accordance to wind direction and wind speed.
