ABSTRACT:
Nonmaterial deflector-enhanced collector (NDC) is a device in which a nonmaterial, such as electromagnetic (EM) wave, provides a medium in which an obliquely incident nonmaterial (IN) can be intercepted and deflected, so that by proper arrangement, some desired objective can be achieved, such as: deflecting, concentrating, diverging, protecting, receiving, propagating/guiding--by many (fiber-optic-like) deflections--the IN. NDC comprises: a projector of nonmaterial, PON, its projected nonmaterial deflector(s) ND, and (intended) collector or receiver, C or R. The projector projects the ND obliquely towards the incident nonmaterial to be deflected, IN (such as EM radiation) so that this IN is deflected towards an intended receiver--if any is present. It may be necessary to ensure build up of proper optical density gradient, in the vicinity of the ND, to encourage refraction and/or total internal reflection of the IN. Variations include where the receiver could be a solar energy collector, in which case its energy-receiving/collecting potential can be greatly enhanced by making far more solar energy available to it; or the receiver can comprise an optical system such as may be used for further manipulation of the deflected IN, as when NDC is used as SECONDARY SUN SYSTEM (SSS). Further, the system could be designed to deflect the IN more than once, as may be required to trap straying rays in enhanced NDC or SSS, or required in multiple deflections needed for lengthy propagation of the IN--as in communication systems. In one simple design of NDC, an annular concave reflective surface converges some incident solar rays towards annular plano-concave lens which substantially collimates and projects these rays as intensified solar beam --the ND--to condition the air of the atmosphere to intercept and deflect other incident solar rays which are approaching in a direction which is oblique to direction of the ND. NDC of various shapes can be made from straight projectors of nonmaterial.
