    Telescoping Shield for Point-Focusing Solar Concentrators (1985)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Telescoping shield normally stowed around solar receiver protects heat engine and supporting structure from overheating when concentrator aimed few degrees away from line to Sun. When extended, shield intercepts off center concentrated solar radiation. Heat spread out over thermally conductive shield and reradiated diffusely not to cause structural damage.

    Out-of-Focus Alinement of Solar Concentrators (1985)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: In new alinement technique, no attempt made to simulate infinitely distant light source, and all mirrors left uncovered throughout procedure. Light source placed at distance of 1,650 feet (503 m); other distances used. Alinement of approximately 250 mirror facets of paraboloidal solar concentrator simplified by precalculated images reflected from all facets. Developed for large solar concentrators, technique used with other multiplemirror or multiple-light-source systems for producing specified illuminance patterns.
