Abstract

Abstract This invention contemplates a solar to thermal energy converter comprising spaced apart light polarizing materials defining a conduit therebetween for the passage of a fluid to be heated, the polarizing materials being positioned with respect to each other, whereby the amount of solar energy transmitted through the collector and hence absorbed by the fluid is controlled. Optionally and preferably, at least one of the light polarizing materials is moveable so that the axis of absorption of the polarizing materials can be adjusted with respect to each other and in reference to collector temperature so that a predetermined amount of light will be transmitted through the device, thereby controlling the temperature within the collector.
