Refrigerator Uses Solar Energy
A REFRIGERATOR which requires no energy other than exposure to sunlight for two hours a day has been developed by Otto H. Mohr, California consulting engineer. Larger solar power units requiring up to four hours exposure can be used for heating or cooling entire homes, according to the inventor. A spherical lens catches the sun’s rays at all hours of the day.
This lens gathers the rays, and changes the light into heat which is transferred to the refrigerating liquid, usually ammonia. The cooling operation is similar to that of ordinary gas refrigerators.
