A vertical axis, fluid turbine device comprises a turbine rotor with a rotatable, central shaft and three to six, equally spaced rotor vane sections connected to the central shaft with adjacent vane sections connected to one another in a framework. This framework rotates about the central shaft with the directional passage of fluid, typically wind, therethrough. Each vane section consists of: a rectangular frame with at least two connections to the central shaft; an elongate hinge section extending substantially parallel to the central shaft and connected to the rectangular frame with two or more rotatable bearings; and a vane panel connected to the hinge section for rotating about the rectangular frame and up to about 180 degrees away from an end of the rectangular frame closest to the central shaft with passage of wind through the framework and with rotation of the rectangular frame about the central shaft. Most preferably, a crossbar extends between opposed sides of the rectangular frame for preventing over-rotation of the vane panel through its frame.
