1. A vertical-axis eolic generator, comprising: i) a driving shaft rotatably connected to a load bearing structure, andii) 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, andeach 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. 2. The vertical-axis eolic generator according to claim l, wherein said plurality of vanes is connected to said driving shaft by at least one pair of spline elements. 3. The vertical-axis eolic generator according to claim 2, wherein said at least one pair of spline elements comprises a top spline element placed at a top portion of said driving shaft and a bottom spline element placed at a bottom portion of said driving shaft. 4. The vertical-axis eolic generator according to claim 3, wherein said top spline element comprises two or more top arms and said bottom spline element comprises two or more bottom arms. 5. The vertical-axis eolic generator according to claim 4, wherein said two or more arms of each spline element are angularly equispaced thereamong. 6. The vertical-axis eolic generator according to claim 4, wherein each vane of said plurality of vanes is connected, at a top part of the vane, to a top arm, and, at a bottom part of the vane, to a first bottom arm, the first bottom arm being angularly consecutive to a second bottom arm opposite to said top arm. 7. The vertical-axis eolic generator according to claim 4, further comprising one or more additional vanes cantilevered on said two or more top arms and/or said two or more bottom arms. 8. The vertical-axis eolic generator according to claim 7, wherein each arm of said two or more top arms and two or more bottom arms comprises at least one additional vane, the at least one additional vane being arranged substantially parallel to a vane of said plurality of vanes connected with said arm. 9. The vertical-axis eolic generator according to claim 2, further comprising a third spline element placed at a central portion of said driving shaft, said third spline element configured to connect each vane of said plurality of vanes to said driving shaft at the central portion of said driving shaft. 10. The vertical-axis eolic generator according to claim 9, wherein said third spline element comprises two or more central arms, said two or more central arms being angularly equispaced thereamong. 11. The vertical-axis eolic generator according to claim 10, wherein each central arm is connected to a vane of said plurality of vanes. 12. The vertical-axis eolic generator according to claim 1, wherein said driving shaft has, along a vertical development of said driving shaft, a plurality of fins configured to serve as generators of turbulence acting in a leeside area. 13. The vertical-axis eolic generator according to claim 5, wherein each vane of said plurality of vanes is connected, at a top part of the vane, to a top arm, and, at a bottom part of the vane, to a first bottom arm, the first bottom arm being angularly consecutive to a second bottom arm opposite to said top arm. 14. The vertical-axis eolic generator according to claim 5, further comprising one or more additional vanes cantilevered on said two or more top arms and/or said two or more bottom arms. 15. The vertical-axis eolic generator according to claim 6, further comprising one or more additional vanes cantilevered on said two or more top arms and/or said two or more bottom arms. 16. The vertical-axis eolic generator according to claim 3, further comprising a third spline element placed at a central portion of said driving shaft, said third spline element configured to connect each vane of said plurality of vanes to said driving shaft at the central portion of said driving shaft. 17. The vertical-axis eolic generator according to claim 4, further comprising a third spline element placed at a central portion of said driving shaft, said third spline element configured to connect each vane of said plurality of vanes to said driving shaft at the central portion of said driving shaft. 18. The vertical-axis eolic generator according to claim 2, wherein said driving shaft has, along a vertical development of said driving shaft, a plurality of fins configured to serve as generators of turbulence acting in a leeside area. 19. The vertical-axis eolic generator according to claim 3, wherein said driving shaft has, along a vertical development of said driving shaft, a plurality of fins configured to serve as generators of turbulence acting in a leeside area.
