Abstract: Improved vertical axis wind turbine includes a rotor (1) arranged to rotate relative to a vertical axis integrated by a central body bearing a plurality of blades (3) connected to the central body through radial arms (2). The rotor (1) is operatively connected to move an electric generator (11). The central body of the rotor (1) is attached on its bottom end, in an operating situation, to a plate (4) that is releasably fastened to a crown (5) with inner gearing of a step-up assembly (10) of planetary gears, with an output torque transmission member that is coupled to a shaft or rotating member of the electric generator (11).

Abstract: Wind generator with protection for flying animals that includes a rotor (1) arranged for rotating about a shaft (4) and provided with a central body (2) and a plurality of blades (3) connected to the central body (2). The rotor (1) is operatively connected for moving an electric generator. At least one of the blades (3) of the rotor (1) has at least one light-emitting element (6) covered by a translucent or transparent luminous cover (5) extending along at least one portion of the length of the blade (3), the luminous cover (5) being made of a light transmitting material capable of transmitting the light emitted by said light-emitting element (6) along the entire length of the luminous cover (5) for the purpose of creating a luminous effect capable of frightening flying animals, such as birds and bats.
