A wind control blade (31) of a wind guide (30) of the present invention forms a 20 wind control blade lateral curved surface gradient angle (32), a 30 wind control blade longitudinal spiral twist angle (33), a 180 wing control blade alignment angle (34), and a 15 wind control blade rear gradient angle (35). In addition, a turbine blade (41) forms a 30 turbine blade lateral curved surface gradient angle (42), a 40 turbine blade longitudinal spiral twist angle (43), and a 120 turbine blade alignment angle (44). The 20 wind control blade lateral curved surface gradient angle (32) and the 30 wind control blade longitudinal spiral twist angle (33) of the wind control blade (31) have more gradual and wider incidence angles than the 30 turbine blade lateral curved surface gradient angle (42) and the 40 turbine blade longitudinal spiral twist angle (43) of the turbine blade (41). Accordingly, since more wind enters into the central direction of the inner side of the turbine blade (41) and a primary whirlwind is generated, much higher acceleration can be obtained.

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.

A contra-rotating dual rotor system may be driven by an electric motor disposed outside of the rotor system. A first rotor may be driven by a drive shaft protruding out from the front (or top) of the motor. A second rotor, mounted to the front of the motor, may be driven by the motor housing itself, via an extension of the motor housing which is coaxial with the drive shaft.
