<p>A toroidal vertical axis wind turbine apparatus (10) has a shaft (14) vertically mounted in a support (12) providing for rotation of the vertically mounted shaft (14) about its longitudinal axis, and a plurality of vertically oriented elongate turbine blades (16), each vertically oriented elongate turbine blade (16) having a length and a width, and a length- wise warp which extends along at least a substantial part of the length of the turbine blade (16), wherein each vertically oriented elongate turbine blade (16) is mounted upon the vertically mounted shaft (14) by support arms (18) such that the vertically oriented elongate turbine blades (16) are mutually spaced and outwardly spaced from the vertically mounted shaft (14) such that when contacted by wind, the plurality of vertically oriented elongate turbine blades (16) move around a toroidal path and cause axial rotation of the vertically mounted shaft.</p> |
