Trapping energy from sun - involves absorbent liq. in basin covered over with foil used as translucent cover

摘要

The appts. is designed to trap solar energy in a liq. It incorporates a container for water or other liq. with a translucent cover acting as a receptacle for rays of the sum. The absorbent liq. in a basin (10) is covered over with a foil (28,32) and in a changeable volume space. USE/ADVANTAGE - Solar energy trapping system. Improved efficiency rectifying the disadvantages inherent in other systems.
