ABSTRACT:
A solar heating panel for converting the sun's rays into heat, comprising a pane of glass, a sheet metal panel behind said pane of glass in spaced relationship therewith, a peripheral hermetical seal between the pane of glass and said sheet metal panel, a vacuum in the space between said pane of glass and said sheet metal panel, said sheet metal panel having a blackened surface facing said pane of glass, and evenly spaced projections pushed out of the plane of said sheet metal panel having sharp points resting against said pane of glass to resist the atmospheric pressure acting on said pane of glass and said sheet metal panel, said blackened surface serving to convert the solar rays into heat to heat up said sheet metal panel, where the heat produced can be carried away by any conventional means, most conveniently by flowing air blown over the back surface of the sheet metal panel to heat a heat sink or a building.
