Claims
- 1. A solar concentrator for directing incident solar radiation to a linear focus, comprising:
- a planar base surface being positioned at an angle .phi., which is greater that 0.degree. but less than 90.degree., with respect to a direction which is normal to said incident solar radiation;
- a plurality of planar reflective elements set along said planar base surface each of which is positioned at an angle .alpha.' with respect to said planar base surface and which varies for each of said planar reflective elements to reflect said incident solar radiation to said linear focus, said plurality of planar reflective elements being separated from each other by substantially planar riser elements, said riser elements being substantially normal to said planar base surface, each of said planar reflective elements making an angle .alpha. with respect to said direction which is normal to said incident solar radiation;
- wherein the magnitude of said angle .alpha. for each of said planar reflective elements is not more than the magnitude of said .alpha. for said planar base surface;
- wherein the magnitude of said angle .alpha.' of each of said plurality of planar reflective elements decreases for said planar reflective elements which are positioned away from a point at which a line drawn parallel to said incident solar radiation through said linear focus intersects said planar base surface;
- whereby all of said incident solar radiation is directed to said linear focus.
