NOVELTY - The turbine (1) has a circular power takeoff ring (27) coaxial with a set of circular tracks and attached to one of multiple trucks (15). A pair of vertical airfoils (51, 53) extends around the circular tracks, where each airfoil is attached to the truck and the power takeoff ring. A set of generators is rotatably connected to the power takeoff ring, where wind power striking the airfoils causes rotational movement of the airfoils and the power takeoff ring and conversion of wind generated rotation of the power takeoff ring and generators to electrical energy.    USE - Orbital track wind turbine for generation of electrical energy from wind power.    ADVANTAGE - The turbine utilizes a set of large blades without using a set of long radial arms for connecting the blades to a central axis. The turbine achieves higher conversion wind efficiency. The turbine can be scaled to larger sizes, and is insensitive to wind direction without the need for long cantilevered rotor blades. The airfoils are light in weight and can be manufactured at reduced cost. The turbine produces electric power at a reduced cost per megawatt hour and reduced tower and footing cost by employing a broad base. The turbine has a set of high maintenance items such as gear boxes, located near a ground for convenience of maintenance. The generators are vertically and movably mounted, thus facilitating lowering and raising of the generators for maintenance, repair and replacement. The entire airfoil acquires maximum tangential velocity of the turbine so that multiple parts of the airfoil produce same amount of power. Each airfoil can be easily transported and brought to a field in multiple sections and assembled into the airfoil, since the airfoil has a constant cross-section shape from top to bottom.
