1. A wind turbine, comprising:
a rotor, wherein the rotor is rotatable with respect to a stator about a vertically aligned rotational axis, wherein the vertically aligned rotational axis passes through a center of Earth, wherein the rotor comprises a first blade portion coaxially aligned with a second blade portion along the vertically aligned rotational axis; and
an electrical generator comprising a generator rotor and a generator stator, wherein the generator rotor is designed to rotate with respect to the generator stator about said rotational axis, wherein the generator rotor is fixed to the rotor of the wind turbine;
wherein the first blade portion comprises a base and a plurality of first blades extending from the base, the first blades being identical to one another and being equally distributed about the vertically aligned rotational axis, wherein each first blade extends from a bottom portion to a top portion and has a maximal vertical height along the vertically aligned rotational axis,
wherein rotation of the first blade portion about the vertically aligned rotational axis circumscribes a circle having a radius Wn,
wherein said second blade portion comprises a bottom housing and a plurality of second blades extending from the bottom housing, the second blades being identical to one another and being equally distributed about the vertically aligned rotational axis, wherein each second blade extends from a bottom portion thereof to a top portion thereof and has a maximal vertical height along the vertically aligned rotational axis,
wherein rotation of the second blade portion about the vertically aligned rotational axis circumscribes a circle having a radius Ww, and
wherein the first blade portion and the second blade portion are fixed with respect to one another, the maximal vertical height for each first blade is at least 1.5 times greater than the maximal vertical height for each second blade, and the radius Ww of the second blade portion is at least 1.5 times greater than the radius Wn of the first blade portion.
