Abstract:
A method for making a paraboloid space frame for directly supporting rectangular mirrors on a solar dish concentrator, said paraboloid space frame containing parabolic trusses with substantially identical focal lengths, said method comprising the steps of:a. providing a plurality of parabolic trusses, said parabolic trusses containing identical focal lengths; b. positioning said parabolic trusses substantially within planes that do not intersect the axis of symmetry of a paraboloid shape; c. positioning said parabolic trusses such that the concave edges of said parabolic trusses lie substantially on the concave surface of said paraboloid shape; d. connecting said parabolic trusses to a support frame; whereby a solar dish space frame will be assembled from identical parts forming an array of identical parabolic trusses containing identical focal lengths for directly supporting an array of parabolic mirrors containing separate and unequal focal lengths as required by paraboloidal dish geometry.
