Abstract:
A hybrid energy conversion system comprising a sun concentrator, a radiation chamber configured to receive high density sun radiation from the sun concentrator, and a Stirling engine operable to convert the high density sun radiation into mechanical energy. The system further comprises a burner arranged to use the radiation chamber as a combustion chamber for combustion of a suitable fuel for operation of the Stirling engine, and an enclosure forming an intermediate space between the enclosure and the chamber. A pressure in the intermediate space is kept higher than a pressure in the radiation chamber. The flow of air through the intermediate space surrounding the radiation chamber will serve to remove any heat escaping from the radiation chamber. Thus, hot spots can be avoided, thereby reducing the risk for leakage caused by such hot spots.

Abstract:
The invention is a solar power system based on the integration of parabolic trough technology and its piping design with solar dish technology. The invention exploits the structural chassis of a parabolic trough based on the design of a torque tube together with its rotational drive unit. An array composed of multiple parabolic dishes is mounted along the torque tube with appropriate individual receivers located next to the focus of each dish. The basic design of the system enables it to be used either to heat thermal fluid flowing through a system of pipes, to concentrate radiation onto Concentrated Photo Voltaic (CPV) cells, or for other dish applications.
