A vertical axis wind turbine includes an elongated rotor propelled by wind-drag, having a high aspect ratio, with a length, L, and diameter, D, wherein 5 < L/D = 15. The rotor is mounted on a pole adapted to be installed in the wind in a vertical orientation. The rotor is constructed from thin vane sheets that form two curved vanes that are supported along their vertical length by vertically extending rigid vane supports located at two different radial locations on the rotor, stiffened by radial ribs. The vane supports support the thin vane sheets and provide transfer of wind induced torque along the vane sheet length to a generator that is located at one end of the rotor and connected thereto to convert rotational energy of the rotor into electricity as the rotor rotates about the central pole and directly drives the generator rotor at the same rotational speed.
