ABSTRACT:
The disclosure illustrates a focusing solar energy collector that has a main reflector made up of a central support rib and a plurality of lateral support ribs extending from the main support to form a series of cross shaped supports for a thin reflective sheet held on the supports by a double faced tape. The central support rib connects with end supports for an evacuated cylindrical glass tube that contains a receiver and a secondary mirror. The secondary mirror is formed from an extrusion and comprises an elongated curved reflective surface having its edges touching the glass cylinder, and an elongated rib also touching the glass to give three point support. A flexible seal is provided between the receiver and the end plates for the glass cylinder to accommodate differential expansion.
