Abstract
Abstract A boiler for powering fluid pressure motors. The rays from the sun are focused by a lens through a transparent oil primary heat transfer medium and onto a heat absorber. The heat directly absorbed by the oil and by contact with the heat absorber is circulated by a thermo-siphon through a heat exchanger. The heat exchanger transfers heat and raises the temperature of a hydrocarbon fluid utilized as the secondary heat exchange medium. The expanded hydrocarbon powers a fluid pressure operated motor and is returned from the low pressure side of the motor to condensers after which it is compressed and returned to the heat exchanger in a closed cycle operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A boiler for producing a source of high pressure fluid from solar energy for use in association with a closed cycle fluid pressure motor, comprising: a chamber with a primary head exchange fluid, energy admission means for passing solar energy into said chamber, absorber means within said chamber and in combination with said primary heat exchange fluid for converting said solar energy into heat energy, heat exchanger means within said chamber for transferring heat from said primary heat exchange fluid to a secondary heat exchange fluid, said primary heat exchange fluid comprises substantially solar energy-transparent oil, whereby said secondary heat exchange fluid develops sufficient pressure to operate said fluid pressure motor.
