1. A parabolic reflector body fabricated on an elongated, convex parabolic mold, the reflector body being of the type which concentrates solar energy along a focal line, comprising:

  • an elongated layered structure having a parabolic concave first side, a convex second side opposite said first side and generally parallel longitudinal edges, the layers of said structure includinga reflective layer on said concave first side which contacts and conforms to the mold during fabrication, anda support layer bonded to said reflective layer on said convex second side, said support layer being predominately formed of an amorphous hard-curing adherent material applied over said reflective layer in a moldable state and conformed generally to the convex shape of the mold, anda tubular beam member bonded to said support layer by adherence of said beam member to amorphous hard-curing adherent material along a side of said beam member, said beam member extending longitudinally parallel to said edges of said layered structure.
