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.

A turbine with flow diverter comprises a support frame adapted to be anchored to a fixed or movable structure, an impeller rotatably mounted about a rotation axis to the support frame and having a front inlet section for receiving the flow and adapted to move continuously upon the rotation produced by the flow between a pushing position and an advancing position in correspondence of the front section, a main flow diverter adapted to be anchored to the support frame and having a peripheral wall adapted to at least partially blind the front section with respect to the flow auxiliary diverter extending from a first section facing one or more blades in the advancing position to a second section facing one or more blades in pushing position. The auxiliary diverter comprises curvilinear conduits in reciprocal side by side position along a radial direction.

A renewable-energy power plant including a first structure, a second structure, a first flue, a second flue and a turbine arrangement comprising at least one turbine, wherein the first structure includes a primary fluid inlet and the second structure includes a secondary fluid inlet and a primary fluid outlet, wherein the secondary fluid inlet is connected to the first flue, wherein the primary fluid inlet is located lower than the secondary fluid inlet and the primary fluid outlet is located lower than the secondary fluid inlet, wherein the turbine arrangement is provided inside the second flue, wherein the power plant includes wetting means arranged to discharge an additive fluid to the working fluid passing through the secondary fluid inlet, wherein the turbine arrangement is arranged to generate power due to the working fluid flowing in a downwards direction inside the second flue and passing through the turbine arrangement.

Solar chimney and method for generating power by the solar chimney are provided. The solar chimney includes a chimney; a heat absorbing surface; a transparent cover located above the surface and forming an air pathway with the surface to the entrance to the chimney; one or more integrated turbine-generators at or before the entrance to the chimney for producing electrical power; and a focusing lens focusing solar radiation on a heat exchanging element to heat air at or just before the entrance to the chimney as it flows to the one or more turbines.

An elevated or ground level vertical cylinder houses one or more propellers and/or turbines that are rotated by heated air convection within or around or above the cylinder. The rotating shafts of the propellers generate electricity in an area at bottom of or below the cylinder. For added, improved air flow directions and volumes; and, for stabilization of the rotating shaft or shafts, a circular pyramid collar structure is disposed below the cylinder. Heat is directed to the cylinder by a plurality of sun tracking concave mirrors that are positioned in concentric circles at various heights. The cylinder may be composed of concrete, ceramics, metal compounds or other materials and operate with a surface temperature that may range 70 to 1,300 degrees Fahrenheit. An optimized system may be constructed on less than one, one or more than one acre of land that could appear as a park like setting.

The present invention features a solar-thermal power generator. The generator makes use of solar energy to heat a component of the generator which leads to the heating of air or fluid within the generator. The rise of the heated air of fluid is channeled towards turbines which turn to produce electrical power.
