Flexible and inflatable solar concentrator for e.g. military pack, has plastic sheets assembled to form volume, where lower face of assembly is treated by aluminum deposition such that lower face forms reflector after inflation of volume

摘要

The concentrator has two plastic sheets assembled by welding (5) to form a volume (1). A lower face (2) of the sheet assembly is treated by aluminum deposition such that the lower face forms a reflector (3) after inflation of the volume. An upper face (4) of the assembly permits the inflation and shaping of the volume. The upper face is made of transparent material i.e. plastic, for allowing the passage of incoming solar rays (6) and secondary rays reflected by the lower reflecting face. The reflecting face concentrates the rays at a point (P) in which a container (7) is arranged.
