<p>solar energy collector comprising a set of two or more reflectors reflecting sunrays at the focal line; a receiver of reflected rays placed at the focal line; and means to move the said set of reflectors along a non- parabolic concave curve. The said non-parabolic concave curve with reference to the focal line is defined by the formula : x2 + y2 = constant (k) y where x and y are the co-ordinates of a point on the said non-parabolic concave curve, in the co-ordinate system, having X axis horizontal, Y axis vertical and the origin of said co-ordinate system on the focal line. The said focal line is perpendicular to the X-Y plane and wherein each of the said reflectors intersects said non-parabolic concave curve.</p> |
