Solar energy collection system

7-9. (canceled)

A reflector wherein receivers are situated in the body thereof on risers parallel to the direction of radiant energy, each said riser bounded by at least one parabolic mirror lying closer and another lying farther from the energy source, where the focus or foci of said mirrors lie substantially in the direction faced by the receiver situated in said riser.

A reflector that focuses light parallel to its optical axis on a plurality of spots located on or proximal to the reflector's surface, said surface comprising:

• a set of reflective faces each of which has the shape of a portion of a paraboloid of revolution whose focal point coincides with one of said spots and whose optical axis is parallel to that of the reflector;
• and a set of receivers such as photovoltaic cells or image sensors straddling said spots.
