ABSTRACT:
A cantilever mounted wind turbine having an interior stationary support column and a concentrically mounted rotatable rotor and having a first bearing between the support column and the rotor and a second flexibly coupled bearing between the support column and the rotor where the second bearing includes bearing surfaces and a flexible coupling between one of the bearing surfaces and the rotor in order to provide bending moment decoupling between the rotor and its support column.
