A disc-type concentrator comprises a disc rack vertical post, a disc rack, a rotating shaft, a rotating reflection mirror, a power driving device, and a control system. The rotating shaft is arranged on the disc rack and rotatably connected with the disc rack. The rotating reflection mirror is arranged on a side of the rotating shaft and fixedly connected with the rotating shaft. The power driving device is arranged on the disc rack or on the back surface of the rotating reflection mirror and driving the rotating reflection mirror to rotate. The control system is connected with the power driving device and controlling the working state of the power driving device.

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.

Disclosed is a solar refraction device (SRD) for heating industrial materials in a heating container, having a bottom, with diffuse solar energy that impinges on an outside surface of the SRD and is refracted through the SRD. The SRD may include a lens array assembly and a plurality of lens panes attached to the lens array assembly. The lens array assembly may include an outside surface corresponding to the outside surface of the SRD, an inside surface, and a plurality of lens array sub-assemblies.

Systems and methods for generating electrical power using a solar power system comprising pressurized pipes for transporting liquid water. The pressurized pipes flow through solar collectors which concentrate sunlight on the water flowing through the pipes. The pressurization in the pipes allows the water flowing through the pipes to absorb large quantities of energy. The pressurized and heated water is then pumped to a heat exchanger coil where the thermal energy is released to produce steam for powering a steam turbine electrical generator. Thereafter, the water is returned to the solar collectors in a closed loop to repeat the process.

Systems and methods for generating electrical power using a solar power system that comprises a pressurized closed loop pipe containing a transfer liquid extending between a solar collector and a heat exchanger. The transfer liquid is heated by the solar collector and gives up its thermal energy at the heat exchange to produce steam. The system also includes a source of geothermal energy and a source of natural gas. The geothermal energy in the form of heat separates the natural gas from the ground water in a separation tank. At the resulting heated ground water from the separation tank is connected to the heat exchanger to supplement thermal energy from the solar collector.

A center of gravity Q1 of a mirror structure 31, which has a plurality of mirrors 32, is located between the plurality of mirrors 32. A driving mechanism 40 that rotates the mirror structure 31 includes a first rotational shaft 52 that has a first rotational axis A1 as a central axis and is supported by a supporting base 80 to be rotatable, a first drive device 60 that rotates the first rotational shaft 52, a second rotational shaft 42 that has the mirror structure 31 fixed thereto, has a second rotational axis A2 which is orthogonal to the first rotational axis A1 as a central axis, and is mounted on the first rotational shaft 52 to be rotatable, and a second drive device 45 that rotates the second rotational shaft 42. The center of gravity Q1 of the mirror structure 31 is located in the first rotational shaft 52 and in the second rotational shaft 42.

A convection-driven power generator comprising a flow intake configured to supply fluid to the generator, a flow duct having a duct inlet and a duct outlet wherein the duct outlet is spaced downstream from the duct inlet along the flow duct, the duct inlet being fluidly coupled to the flow intake. A heating chamber fluidly is coupled to the duct outlet so as to receive fluid from the duct outlet, the heating chamber comprising an external wall configured to transmit light radiation incident thereon such that fluid within the heating chamber is heated by the transmitted light radiation. 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 elevated or ground level vertical cylinder contains a cone structure that may have an exterior lower static screw auger blade that adds cyclonic turbulence to the rising heated air within the cylinder. The additional turbulence increases the speed of a top propeller which increases the amount of electricity generated. The lower screw auger blade may also be connected to an upper screw auger blade and rotate freely around the cone in response to the rising air in the cylinder to add further torque to a vertical drive shaft. Voids in the cylinder may be used to secure mirrors or lenses to increase the temperature of the cylinder. Mirrors may be attached to the cone to further reflect solar energy to increase the air temperature within the cylinder. The outside perimeter of the cylinder receives solar energy by use of mirrors and lenses directed toward the cylinder.
