<p>A collector of solar energy has, in cross-section, the profile of a nested, truncated and inverted trough which is formed as an array (12) of concentric annular conic frusta. The array ascends from a base, defined by the outermost frustum, to a vertex defined by the innermost frustum. The collector is disposed intermediate the Sun and an absorber (42) of solar energy. The collector is operatively connected with Sun-tracking means (26) for movement in a predetermined direction and through a predetermined distance relative to the center of the remote absorber. The frusta (12) have reflective inner surfaces, each of which is defined by a singular and unique parabola. Light incident upon the surfaces is transmitted by a single reflection, through the openings at the base of the trough, onto a common focus located at the absorber (42) for the optimal concentration of the collected radiation which may be utilized as thermal energy or converted into other useful forms of energy.</p> |
