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.

A wind-energy-power-generating device is disclosed for flotation on a body of water. The device includes a turbine assembly having rotor blades rotating about a rotation axis for harnessing kinetic energy from an airflow. The device includes a cowl at least partially surrounding said turbine assembly and defining an airflow passageway between a cowl inlet and outlet, having an inlet and outlet axis, respectively. The inlet and outlet axis intersect at a redirect angle. The device includes a base platform adapted to support the turbine assembly and cowl on the water. The cowl is rotatably mounted on the base platform such that it is rotatable around the turbine assembly to self-align with a wind direction. Stabilising arms extend from the base platform and are spaced circumferentially around a platform axis, to stabilise it on the water. A wind-energy-power-generating device secured to the ground or other fixed non-floating structure is also described.
