Abstract: An inverted funnel-shaped columnar tower (115) includes a window region (120), a heat absorbing surface (130), an air entrance (116) and exit (117). Solar energy passes through the window region and heats the heat absorbing surface. A plurality of fans (145), each connected to a generator (150), are suspended within the tower and extract energy from convectively rising air, generating electricity. A fan (160) outside the tower intercepts wind and turns an internal fan (145?) that aids the convective flow, providing a self-starting feature. A plurality of rotors (100) with wings (705) are connected in groups to generators (725) and all are arranged adjacent the tower. The rotors intercept wind energy and deliver it to the generators for conversion to electricity. The rotors include a flap (800) that predetermines the direction of rotation of the rotor, providing a second self-starting feature. The convection and wind capture functions operate independently.

Abstract: A helicopter and aircraft power device has a plurality of fluid inlets on a windward side of a blade housing and a plurality of fluid outlets on a leeward side in a manner that the fluid inlets communicate with the fluid outlets. The path where the fluid flows in the lengthwise direction on the windward side of the blade housing is far greater than the path where the fluid flows in the widthwise direction on the leeward side of the blade housing, generating a very large pressure difference between the leeward side and the windward side. The action of the centrifugal force and a suction force from a suction motor significantly increase the flowing speed on the windward side of the blade and in the fluid passage, generating bigger pressure difference on either sides of the propeller and thus forming more powerful lift force and driving force.

Abstract: One embodiment of a continuous wind power system with auxiliary blades comprises of a general generator (150) and six sets of auxiliary blade sets (120) each propelled by a motor (130) of its own. Motors (130) are powered up by batteries, solar panels, or by a fraction of power generated by the generator (150).

A transmission device transfers the rotary motion of the mounting device (110) of auxiliary blade sets (120) and motors (130) to the shaft of generator (150A) and results in production of electricity.
