ABSTRACT:
A solar energy absorber including a tubular absorber surface through which a fluid passes for transferring thermal energy from the absorber to other devices. Positioned above the tubular absorber surface are a plurality of spaced glass layers. Positioned between an upper layer and the next layer is vacuum or air for minimizing thermal energy losses through convection. A clear liquid passes between two intermediate layers of glass for transferring by means of conduction the thermal energy absorbed therein by either the initial passage of the visible spectrum of electromagnetic rays or by infrared radiation radiated from an absorber positioned therebelow.
