Collapsible Solar-Thermal Concentrator For Renewable, Sustainable Expeditionary Power Generator System

摘要

A solar-thermal concentrator for a expeditionary power generator system including a portable power plant that utilizes a hybridized solar/fuel Stirling engine to supply electric power in an expeditionary setting. The concentrator includes a collapsible dish assembly that is pivotably and tiltably mounted on a portable base assembly, where the dish assembly includes a lightweight frame including a central mounting structure and multiple truss-like radial arms that are rigidly connected to and extend radially from the central mounting structure, and a reflector panel assembly including multiple flat, fan-shaped reflector panels that are secured to the frame and disposed in a semi-circular pattern. Each reflector panel includes multiple reflectors that collectively form a substantially flat Fresnelized reflective surface that redirects incident sunlight into a focal region. The power plant is maintained in the focal region by a support structure that extends extending perpendicular to the flat reflective surface.
