Three Target Vacuum Tube:

Each evacuated tube is composed of two concentric glass tubes; the inner one is coated with highly selective layer and it converts solar radiation into thermal energy, as for the outer one, it is a cover to keep the vacuum . Both tubes are fused together and the gap between them is evacuated to achieve excellent thermal vacuum insulation.
