Abstract:
1. An economical solar generator system wherein the solar energy collector is constructed from a plurality of heat exchangers of the kind used as condensers in automotive air conditioners or as radiators in engines, said solar generator system comprising: a plurality of said heat exchangers connected to receive incoming liquefied refrigerant under pressure, the number of such heat exchangers being interconnected being sufficient to raise the temperature of refrigerant to the range of 120° F. to about 190° F. and induce a phase change from the liquid to the gaseous state; a pump coupled to said plurality of heat exchangers for providing said incoming refrigerant under pressure; an air motor coupled to the outflow heated gas from said plurality of heat exchangers whereby said air motor is rotated by said heated gas; an electrical generator coupled to said air motor so that rotation of said air motor causes rotation of said generator; and a condenser in fluid communication with said air motor to induce a phase change in said refrigerant from a gas phase to a liquid phase, the output of said condenser coupled to said pump; wherein the condenser further comprises a hot storage tank, a cool storage tank, wherein at least one of the hot and cool storage tanks is configured to promote sufficient passive heat transfer to cool the cooling liquid during the night at least to the first temperature.
