Multiple
horizontal axis type rotors are coaxially attached along the upper section of an elongate torque transmitting
tower / driveshaft, The
tower / driveshaft projects upward from a cantilevered bearing means, and is bent downwind, until the rotors become sufficiently aligned with the wind to rotate the entire
tower / driveshaft, Power is drawn from the shaft at the base. Surface
mount, subsurface
mount, and marine installations, including a sailboat, are disclosed. Blade-to-blade lashing, and
vertical axis rotor blades may also be included. Vertical and
horizontal axis type rotor blades may be interconnected along the length of the tower / driveshaft to form a structural lattice, and the central shaft may even be eliminated. Aerodynamic lifting bodies or tails, buoyant lifting bodies, buoyant rotor blades, and methods of influencing the tilt of the rotors, can help elevate the structure. This wind
turbine can have as few as one single moving part.
