Claim:
A system, comprising: a primary Parabolic Total Reflection Reflector (PTRR) that collects incident sunlight and reflects a wide beam of rays, the primary PTRR comprising at least one Corrected Rectangular Prism (CRP) that enables correct focusing; a secondary Ellipsoidal Total Reflection Reflector (ETRR) that receives at least a portion of the wide beam of rays and focuses the wide beam of rays into a narrow beam of rays, the secondary ETRR comprising at least one CRP that enables correct focusing; one or more solar arteries that receive at least a portion of the narrow beam of rays and guide at least the portion of the narrow beam of rays under total reflection, the one or more solar arteries comprising at least one Corrected Rectangular Prism (CRP) that minimizes radiation propagation losses; one or more elements accessory to the one or more solar arteries, the one or more elements guide sunlight in at least the portion of the narrow beam of rays that is received by the one or more solar arteries, wherein the one or more elements comprise at least one CRP that minimizes sunlight propagation losses; and reflectors formed from CRPs, which define a solar radiation beam path for reflecting or propagating solar radiation to an intended destination and defined by a curvature of the system having a focal center of curvature (E) for focusing the solar radiation beam, wherein the reflectors comprise (i) a front surface, which is oriented towards the solar radiation beam path and is smoothly curved in correspondence with the curvature of the solar system, and (ii) a rear surface comprising essentially rectangular prisms with tops of the essentially rectangular prisms enveloped by a curvature parallel to that of the front surface, further wherein in cross-section of an essentially rectangular prism in a plane at least locally perpendicular to the longitudinal tangent of the essentially rectangular prism's top acme: separate sides of the essentially rectangular prisms are curved for a corrected accurate focusing, and in the section of the front surface, for each essentially rectangular prism, a mid point is defined as a perpendicular projection of a top acme point of the essentially rectangular prism onto the section of the front surface, and an intersection point is defined as a perpendicular projection of a selected point on a curved side of the essentially rectangular prism onto the front surface intersection curve, and wherein a tangent in each point along the curved sides has an orientation angle relative to the orientation of the sides at the top acme point corresponding with and dependent on a predetermined angle formed between intersecting tangents at an intersection point and the mid point.
