ABSTRACT:
Apparatus for converting the energy of the wind into mechanical energy for use in the generation of electricity comprises an upstanding column a fan which is freely rotatably mounted on the column and which comprises circumferentially spaced, radially extending blades and, supported by and freely rotatable about the axis of the column, a turbine which surrounds and is radially spaced from the column and which comprises circumferentially spaced blades extending lengthwise with respect to the column. Preferably, an annular body is supported by the column and has an upper surface of such a shape as to encourage laminar flow of the wind over its surface. Preferably, also, over an upper part of its length immediately below the fan the column has circumferentially spaced, helically extending fins 4 defining passages wind being caused to flow upwardly within the passages to form a vortex. Circumferentially spaced blades depending from the annular body define, between adjacent blades, venturi through which wind is directed on to the blades of the turbine.
