Patent ID: 8752380

Claim:
A collapsible solar-thermal concentrator for a renewable, sustainable expeditionary power (RSEP) generator system, the collapsible solar-thermal concentrator comprising: a base assembly; and a semi-circular dish assembly that is mounted on the base assembly such that the dish assembly is pivotably and tiltably movable relative to an underlying support surface, the dish assembly including: a frame comprising a central mounting structure and a plurality of radial arms that are rigidly connected to and extend radially from the central mounting structure in a semi-circular pattern, and at least one curved member connected to the plurality of radial arms, wherein front surfaces of the plurality of radial arms define a plane, and where the frame is movable between a horizontal position in which the frame is parallel to the underlying support surface, and a vertical position in which the frame is perpendicular to the underlying support surface; a reflector panel assembly including a plurality of flat, fan-shaped reflector panels secured to the frame and disposed in a semi-circular pattern, each of the reflector panels including a plurality of reflectors that collectively form a substantially flat Fresnelized reflective surface that redirects incident sunlight into a focal region, and a support structure having a fixed end connected to the central mounting structure of the frame, at least one elongated beam extending perpendicular to the plane defined by the frame, and a free end disposed adjacent to the focal region defined by the Fresnelized reflective surface.
