ABSTRACT:
A sunrays focusing apparatus for obtaining highly condensed solar energy. The apparatus includes a first trough-shaped parabolic reflector mounted for rotation about both vertical and horizontal axes.
A first elongated refractor is mounted to the first parabolic reflector along or adjacent to the focal axis of the first parabolic reflector.
A second trough-shaped parabolic reflector is also mounted to the first parabolic reflector in such a way that focal axes of both first and second parabolic reflectors are disposed at right angles to each other.
A second reflector is mounted to the first parabolic reflector along or adjacent to the focal axis of the second parabolic reflector. Mounted on the second parabolic reflector is a sun tracking device responsive to sunrays for directing the first parabolic reflector towards the sun.
