  • a conical or pyramidal needle with a reflective surface can be carried on its symmetry axis and in the area near the cusp a cone or pyramid of material that is equally reflective and resistant to high temperature. In the vicinity of the cusp you can place a small concentrating lens of the sun's rays. The area near the vertices of the dihedral mirrors are resistant to high temperatures.
  • Mirrors can also be conical-helical.
  • the flexible reflector elements of the mirrors consist of a film of a highly reflective metal silver, aluminum, chrome, copper, reflective polymers, sol-gel type mirrors, etc., coated or between thin plastic films, varnish, etc. , or of a metal or plastic plate or sheet covered with a silver or aluminum film that acts as a reflector.
  • a variant uses a plate or sheet metal polished, anodized or with a bath of a reflector metal, also aluminized plastic or nickel-plated bronze.
  • the silver or aluminum film, Polished or anodized surface is coated with a transparent layer of metal, resin, polyester or similar varnish that acts as a protective against environmental corrosion.
  • the mirror can be reinforced or supported by a cloth, mesh of fine threads or crushed and equally reflective strips forming large boxes, or by groups of parallel threads on one or both sides. It can also rest on a mesh, grid or independent plate. Flat mirrors can be held by rigid arms.
  • the mirrors are the lateral faces of cone trunks or pyramid trunks, flat, angular or dihedral elements, their construction with rings, contour of the polygons or edges that make up the frame, support of the reflective sheets, and the plates may be sufficient.
  • corresponding cords or cables and the baffle elements in the form of bands or strips, which run in parallel sections or contouring the lateral faces of the cones and pyramids.
  • the baffle elements can be held between meshes or parallel wire assemblies.
  • Flexible reflector elements are attached to the frame and ribs by means of staples, nails, rivets, cables, cord assemblies, nets, sewn, glued, hem, etc. You can use overlapping or concentric cone or pyramid trunks separated from each other by means of spacers.
  • D ⁇ edrico type mirrors can be placed between the upper ends of some posts and held by the upper vertices by means of cables or ropes with an elastic portion, which allow them to be directed towards the sun by manual or automatic actions and pulleys that facilitate the sliding of the rope.

  • Mirrors can consist of multiple small mirrors. A set of angularly arranged curved or parabolic mirrors determine or create curved channels that converge in a cylinder or focal duct. You can use multiple mirrors or reflector elements arranged horizontally and with one inclination such that it creates lateral channels that concentrate the sun's rays in a focus.
