Spiral Concentrating Collector with Moving Receiver

A solar energy concentrating system having:

• a) at least one linear trough solar energy concentrating reflector having a reflective surface disposed with a concave curvature shaped as a section of a spiral;
• b) a means of absorbing the solar energy reflected into a solar energy receiver, a conduit through which an energy transfer fluid circulates, the energy transfer fluid being heated by the reflected solar energy received from the concentrating reflector;
• c) a means of supporting the solar energy receiver over and above the reflective surface, the receiver support means being fastened to a structure connected to the concentrating reflector, dimensioned to support the weight of the absorber and to provide a path for the linear solar energy receiver to move along said path defined by the upper edge of said receiver support, and;
• d) a means of moving the absorber along the path defined by the upper edge of the receiver support;
