  • System for extracting energy from wind and thermal gradients
    Patent number: 10184453
    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.
