Abstract:
1. An air heating system for use with a mechanism for flowing air, comprising a solar absorber, a backing wall, a first element, and a second element, wherein said solar absorber has a solar absorber first end and a solar absorber second end, wherein said solar absorber has a rigidity sufficient to provide and maintain an average shape that is convex when said solar absorber first end is connected to said backing wall, a force to bend said solar absorber into said convex shape is applied, and said solar absorber second end is connected to said backing wall, wherein said first element and said second element have a gap there between and are configured for holding said solar absorber second end so said solar absorber has said convex shape when said solar absorber is viewed from outside of said solar absorber, wherein said convex shape provides a plenum for air flow, wherein said plenum extends in an axial direction between said solar absorber and said backing wall, wherein said solar absorber is dark colored and permeable to air, wherein when the mechanism for flowing air is connected to said plenum air is pulled into said plenum through said dark colored permeable solar absorber, wherein distance between said solar absorber and said backing wall defines a plenum depth, wherein said plenum depth is sufficient under most of said solar absorber so air entering said plenum through most of said solar absorber is pulled primarily in said axial direction.
