Wind power assembly for generating electrical energy in a motor vehicle

The turbine has a generator unit (1) arranged in a cannel area (2), and an air-conducting plate element arranged in a flow direction in front of the generator unit. The plate element regulates air stream inflow till to a non-flowing of the generator unit based on velocity of a motor vehicle, where the air stream is produced during movement of the motor vehicle. A feeding hopper (5) for the air stream is arranged in the channel area in front of the plate element, where the plate element is designed as a curved guiding-blade (9).
