Abstract: A solar collector (1) includes two panels (2, 3) of which at least one panel (2) can be designed as a solar module, wherein the panels (2, 3) are connected to each other and held spaced apart from each other by webs (5) that are distributed over the surface of the solar collector (1). The webs (5) between the panels (2, 3) of the solar collector (1) are arranged in such a manner that the interior space (4) is divided to form a flow path, which can be achieved as a result of the fact that the webs (5) start alternately from one edge (9, 10) of the solar collector (1) and are spaced from the opposite edge (10, 9). The webs (5) are strips that are connected via plastic strands (12) to the inner faces of the panels (2 and 3).

Abstract: A solar furnace includes an outer insulation chamber and an inner reaction chamber disposed inside the outer insulation chamber. The outer insulation chamber has an outer solar window which is in alignment with an inner solar window of the inner reaction chamber. The outer insulation chamber includes a multi-layered air-circulating tunnel. Each layer of the air-circulating tunnel has a solar window to form a multi-solar window opening. Within each solar window opening, there is a hot air curtain or hot flame curtain to cover the opening. When the concentrated solar beams pass through each solar window opening, photon beam reacts with the hot air curtain or hot flame curtain, and will further increase the temperature of hot air particles in the multi-layered air-circulating tunnel. An oil boiler is thermally connected to the inner reaction chamber. The oil boiler includes incoming and outgoing pipes disposed in a middle air-circulating tunnel to absorb the heat energy from the hot air curtain.
