Radiation collection apparatus with flexible stationary mirror

A radiation collection apparatus comprising:

• a stationary radiation focusing element having a fixed radius of curvature, and characterized in that solar radiation incident on the radiation focusing element is focused on a circular path of focus that intersects said radiation focusing element on at least one point;
• a support structure contacting said radiation focusing element to hold said radiation focusing element fixed in a region about said at least one point, while allowing flexure of other regions of said radiation focusing element;
• a radiation receiving element constrained to move relative to the radiation focusing element in said circular path of focus so that solar radiation incident on the radiation focusing element region held fixed by said support structure is naturally reflected and focused on said radiation receiving element;
• and
• an adjustment mechanism including a rotary element disposed above said radiation focusing element at a center of said circular path of focus constrained to rotate in relation to the movement of said radiation receiving element, and at least two links oppositely coupling said rotary element to said radiation focusing element at locations removed from said at least one point so as to oppositely flex the radiation focusing element at said removed locations in relation to the rotation of said rotary element to compensate for focusing errors.
