WIND-ELECTRIC PLANT FOR MULTI-STOREY BUILDINGS AND STRUCTURES Russian patent published in 2011 - IPC F03D3/02 F03D3/04 

FIELD: power engineering.

SUBSTANCE: wind-electric plant comprises a wind wheel and a generator. The generator shaft is installed on one axis of two wind drives, one of which is rotated by natural movement of air masses, and the second one - under action of difference pressure pulled in the vertically arranged exhaust pipes or channels. Between the drive shafts there is an electromagnetic friction device, which disconnects the first wind drive from the second one at zero speed of outer air movement, that is in case of calm. The wind-wheel driven by air masses, by 1/2 is covered with a device of weather vane type at the windy side, and the device rotates around its axis.

EFFECT: making it possible to produce power even at zero speed of natural movement of air masses.
