A flow exhaust is fluidly coupled to the heating chamber and configured to exhaust fluid heated by the heating chamber from the heating chamber. A turbine is arranged within the flow duct, downstream of the flow intake, and exposed to fluid flow through the flow duct such that when fluid flows through the flow duct the turbine is caused to rotate by the fluid flow; and at least one lens element is configured to focus the light radiation transmitted by the external wall within the heating chamber.

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.

In general terms the present invention proposes a device 100 for harvesting renewable energy. The device 100 comprises a wind turbine 140, a channel 160 for directing wind 198 to the wind turbine 140, and a solar receiver 155 positioned on an internal of the channel 160 for receiving sunlight 194 entering the channel 160.

The present invention relates to a solar power generating apparatus comprising: a body (100) having a three-dimensional shape so as to enable air flowing from the outside to be lifted, and having an acceleration flow path (142) formed on the top thereof so as to induce a bottleneck phenomenon of the air to be lifted; and a power generating fan (200) installed in the acceleration flow path (142). Accordingly, the air flowing into the body (100) is heated by sunlight and is lifted so as to operate the power generating fan (200) and enable power generation, such that eco-friendly energy can be produced.
