Convection-type solar heating unit
A solar heater comprises a plurality of elongated containers which are nested within one another, each container having a transparent upper surface positioned to admit solar radiation to the container. Each container includes an inlet adjacent to one end thereof for the admission of a gaseous medium such as air of some other gas such as carbon dioxide, to be heated by solar radiation within the container, and further includes an outlet for the heated gaseous medium adjacent to its other end. The gas outlet of each container is connected to the inlet of the next inner one of the nested containers, and the outlet of the innermost container is connected to the inlet of the outermost container, so that the gaseous medium flows continuously to and through each of the nested containers to cause the medium to be heated to successively higher temperatures as it flows through said containers in succession. The innermost container includes a thermocouple junction, or a boiler containing water for conversion to steam by the heated gaseous medium. Plural nested-container units can be arranged in series with one another, with the respective boilers of said plural units also being connected in series, to increase the efficiency of the device.
