NOVELTY - The assembly has a double wind turbine (260) mounted on a common floatable support (266) for facing oncoming atmospheric wind. An electrical generator is mounted in engagement with the turbine for generating electricity in response to rotation of the turbine. The turbine includes an axle structure and sail wings extending radially from the structure. A unit applies longitudinal force to the structure along a clockwise direction facing the wind, and comprises submerged sea anchors (272A-272C) e.g. pier anchors, and an anchor suspension line (274) connected between the anchors and the structure.    USE - Double wind turbine assembly for generating electricity on a water body e.g. ocean and lake, to supply power to large cities. Can also be used for pumping water from a ground.    ADVANTAGE - The anchor suspension line is attached to a turbine wheel at an axis of rotation to prevent tilting of the turbine in response to high wind conditions. The assembly reduces the longitudinal force applied by the turbine wheel to the tower or other vertical support of the turbine in an effective manner. The assembly allows a thruster to be mounted to a stern of the floatable support, so that the anchors stabilize a bow of the floatable support when the thruster swings the stern in alignment with the bow and the wind, thus assuring that the turbine wheel directly faces the wind, and causing efficient rotation of the turbine wheel. The assembly allows an air bearing to reduce friction between a rotor and stators. The assembly reduces rolling of the floatable support and the assembly supported on the floatable support. The assembly reduces the expense of having a tall tower as usually required for land mounted wind turbines, as less turbulent winds at the surface of the water allow the turbine wheel to be supported lower, closer to the surface of the water.    DETAILED DESCRIPTION - The floatable support is a pontoon boat and barge floatable support.    DESCRIPTION OF DRAWING(S) - The drawing shows a side elevational view of a double wind turbine.
