Abstract: A wind turbine for attachment to an upstanding post, the turbine comprising a two-piece mounting bracket; a cylindrical sleeve coupled to the mounting bracket; a turbine blade apparatus rotationally coupled to the sleeve, wherein the axis of the sleeve defines the rotational axis of the turbine blade apparatus, the turbine blade apparatus comprising a lower blade support plate; an upper blade support plate; and two or more turbine blades located between the upper and lower blade supports, wherein a first end of each blade is coupled to the lower blade support and a second end of each blade is coupled to the upper blade support; and an electrical energy generator driven to rotate by the turbine blade apparatus, wherein the electrical energy generator generates electrical energy when the turbine blade apparatus rotates relative to the sleeve.

Abstract: A wind turbine comprising a two-part collar; a two-part turbine blade assembly, wherein the two parts are coupled together and the turbine blade assembly is rotatably coupled to the collar; an electrical generator comprising a rotor and a stator, the electrical generator being operatively coupled to the turbine blade assembly such that rotation of the turbine blade assembly relative to the collar results in a corresponding rotation of the rotor.
