Abstract

A solar heating system for heating fluid enclosed in a waterproof, heatable flexible bag held in a support which can be a cavity in the earth, insulated from ambient temperatures by alternate layers of transparent flexible gas bags and liquid bags disposed above the heatable bag. An upper weight bag filled with liquid applies weight down against the heatable bag to apply pressure on it to raise the boiling point of the liquid therein. A heat exchanger receives hot fluid from the heatable bag to produce hot gas such as hot freon under pressure to operate a turbine. The turbine can deliver electricity for electrical power for producing hydrogen and oxygen gases, for heating and for other uses including electrical power for municipalities.
