  • Patent number: 9467089
    Abstract: A solar concentrator comprises a pair of concentric reflectors having a spindle toroid geometry for focusing the collected solar radiation into a ring-shaped focal area, as opposed to the “point” or “line” focus of prior art configurations. In a preferred embodiment, each reflector is formed of a plurality of curved petals that are disposed in a contiguous, keystone arrangement that requires no additional fixturing to hold the petals in place. Such an arrangement reduces the weight, complexity and cost of the final solar concentrator structure.
    Type: Grant
    Filed: February 26, 2014
    Date of Patent: October 11, 2016
    Assignee: CEWA TECHNOLOGIES INC.
