Claims19
A vertical-axis eolic generator, comprising:
- i) a driving shaft rotatably connected to a load bearing structure, and
- ii) a plurality of vanes,
- wherein:
- said driving shaft is integrally coupled to said plurality of vanes, each vane extending along a substantially rectilinear longitudinal axis,
- an arrangement of said plurality of vanes with respect to said driving shaft is such that said plurality of vanes and said driving shaft are configured to describe, during a motion of said plurality of vanes, a surface substantially a hyperboloid of one sheet, and
- each vane of said plurality of vanes has a substantially crescent-shaped profile, the substantially crescent-shaped profile having an axis of symmetry, wherein each vane has a twist adapted to maintain convexity of said substantially crescent-shaped profile facing said driving shaft along a longitudinal development of said vane.
