Zusammenfassung:There has been provided an evacuated tubular solar collector wherein a relatively long extraordinarily large diameter glass tube having sealed hemispheric-like ends surrounds a corresponding large absorber therewithin. A conduit, in heat exchange relation with the absorber, passes through the envelope by means of a hermetic seal. The conduit provides a fluid flow path for a working fluid. Important parameters include, at least one of a ratio of tube diameter to tube length and absorber area to the length of the conduit.
