WIND TURBINE APPARATUSES

A wind turbine apparatus comprising: a blade portion 6; a generator 8 comprising a stator 12 having a plurality of coils 20 and a rotor 10 having a plurality of magnets 22, 5 the rotor 10 being connected to the blade portion 6 such that rotation of the blade portion 6 and rotor 10 generates a current within the coils 20; wherein the blade portion 6 is connected to the rotor 10 by a yoke 24 which extends around the generator 8 and is connected to the base of the rotor 10 such that the magnets 22 of the rotor 10 and the coils 20 of the stator 12 are disposed between the blade portion 6 and the 10 connection between the yoke 24 and the rotor 10. A stator 12 comprising a shaft 114 is also described, the shaft 114 having a first terminal portion 34 and a second terminal portion 36 separated from one another by an insulator 38, the first and second terminal portions 34, 36 being electrically connected to the coils 20; wherein the shaft 114 is received by openings 40', 40" provided in first and second conductive rails 4b', 4b" so 15 as to support the generator 8 and blade portion 6 and such that the first and second terminal portions 34, 36 are electrically coupled to the first and second conductive rails 4b', 4b" respectively to carry the current from the coils 20.
