ABSTRACT:
Apparatuses and methods for an improved wind turbine and blade assembly are disclosed. The wind turbine has a wind turbine assembly being rotatably driven by the blade assembly. The wind turbine assembly has a shaft connected to an inner wheel by a supporting structure. A magnet array is disposed circumferentially about the inner wheel. A transformer array is disposed circumferentially about an outer wheel. The shaft rotates the inner wheel with the magnet array within the outer wheel having the transformer array for producing electricity. Blades are held in a neutral position into the wind by tensioning means.
