  • the storage unit is further designed such that it transfers the tilting movements of the Magnus rotor to the generator unit, which converts these into electrical energy.
  • the wind power plant according to the invention has the regulation unit which controls the wind flow of the Magnus rotor. This makes it possible to completely prevent the flow of a tilted or inclined Magnus rotor, which leads to a drop in the acting lateral force and thus to a pivoting back of the Magnus rotor against the tilting movement caused by the lateral force.
  • the embodiment of the wind turbine according to the invention is characterized in that all assemblies can be arranged substantially at ground level.
  • the wind turbine according to the invention compared with conventional Ania- gene with rotor blades on a small space and is perceived as less disturbing for residents in the area of the plant.

  • the regulating unit is adjustable between a flow of the Magnus rotor completely blocking and a full flow permitting position.
