WIND-DRIVEN ELECTRIC GENERATOR Russian patent published in 2011 - IPC F03D5/00 F03D11/04 

FIELD: power industry.

SUBSTANCE: according to the first version, in energy conversion method there provided is at least one circulating element directed along closed loop and located horizontally above the ground and on which the retaining ropes and/or chains with load-carrying housings having transverse section of flow application force and adjustable as to length are attached at least in two opposite lying positions, and at that: a) retaining rope or chain, which are installed in the section directed in horizontal flow direction, is installed with bigger length than the retaining rope or chain, which are installed in the section directed opposite to horizontal flow direction; b) lengths of ropes in the area of turning points of circulating element, in which circulating element stroke relative to the flow is turned in backward direction, are chosen so that they meet again the requirement specified in a). The second version describes energy conversion method at which there provided is at least one circulating element directed along closed loop and located horizontally above the ground and on which retaining ropes and/or chains are fixed at least in two opposite lying positions; free ends of the above ropes and/or chains are provided with load-carrying housings having transverse section of flow force; at that, transverse section of force application of load-carrying housing is changed so that transverse section of force application of load-carrying housing, which moves in horizontal flow direction, is more than transverse section of force application of load-carrying housing moving in opposite direction.

EFFECT: application of the method will provide effective conversion of kinetic energy of air flows to mechanical or electric energy.
