ABSTRACT:
A plurality of thermoplastic sheets of film are heat sealed to form complementary first and second heat transfer chambers for a pressurized fluid that is supplied to one of the chambers and which flows to the other of the chambers through an opening in the film intermediate the chambers. The film exposed to sunlight is transparent permitting solar energy to impinge upon a film disposed within the chambers for heating the chambers. Fluid ducts are connected to the apparatus for supplying the fluid under pressure to one of the chambers and for receiving the heated fluid from the other of the chambers.
