Abstract:
1. A concentrated solar power system, comprising: an absorber tube; a working fluid contained within the absorber tube; a housing through which the absorber tube extends; a support plate positioned in the housing above the absorber tube; a plurality of space-apart, planar optical wafers with a first end supported by the support plate and a second end positioned proximate to an outer surface of the absorber tube; and a lens array including a plurality of linear Fresnel lenses positioned side-by-side with longitudinal axes in a parallel arrangement, wherein each of the linear Fresnel lenses is spaced apart a lens array height from one of the first ends of the optical wafers and has a focal point proximate to the first end so as to focus received sunlight into the optical wafer associated with the first end, wherein the second ends of the optical wafers are arranged to be substantially parallel to the longitudinal axis of the absorber tube and are spaced apart about substantially the entire circumference of the absorber tube.
