A vertical wind-driven electricity generation device is described, which, in one embodiment, utilizes a segmented Savonius rotor and which is easily handled, transported, assembled and maintained, even by a single person. The blades of the rotor are segmented into a plurality of modest size blade segments, each of which comprises two, low height, helically-curved blade portions. The blade segments are preferably of the same height and diameter. The rotor is mounted on a central vertical shaft connected to a generator. When the plurality of blade segments are installed on the device's central shaft, the overall blade configuration functions as an unitary Savonius rotor. Flow of gas (normally air in the form of wind) causes the rotor to move, turning the shaft and rotating member of the generator to rotate, causing the generator to produce electricity.
