PCT No. PCT/EP89/01103 Sec. 371 Date Aug. 3, 1990 Sec. 102(e) Date Aug. 3, 1990 PCT Filed Sep. 22, 1989 PCT Pub. No. WO90/04102 PCT Pub. Date Apr. 19, 1990.The present invention relates to a rotor driven by wind power with a vertical rotating axis and radial arms distributed at uniform angular intervals over its periphery which bear bodies with an aerodynamic profile such that one side of the profile exhibits a lower air resistance with a current at right angles than with a current from the opposite side. Known vertical rotors should be of simple construction and should be capable of being manufactured at low cost. At the same time their efficiency should be high enough for them to be used to generate wind power economically. To this end, the rotor of the generic type is improved such that the rotor arms consist of one or a plurality of loops in vertical planes with an aerodynamic profile, where the profile shape is maintained essentially uniform over the entire length of the loop.
