Solar energy collection system

DETAILED DESCRIPTION My invention is a solar energy collector.
This collector includes a manifold.
The invention also includes a plurality of double-wall tubular members.
The space between the walls is sealed at a sub-atmospheric pressure.
The tubular members each have a closed end remote from the manifold and an open end in sealing engagement with the manifold.
The outer wall of the double-wall tubular members is a transparent glass material which is transparent about its entire circumference.
The double-wall tubular members are all spaced apart on centers no more than four times the diameter of the double-wall tubular members.
A means is provided for supplying a fluid media from the manifold to the interior of the plurality of tubular members and for returning the fluid media to the manifold.
A diffuse-reflecting surface is positioned on the side of the tubular members away from the sun, the diffuse-reflecting surface being co-extensive with all of the tubular members.
The diffuse-reflecting surface is positioned no more than four times the diameter of the tubular members away from the center line of the tubular members.
