|Greg's solar air heating collector uses recycled aluminum soda pop
cans for the absorber. The pop cans have the tops and bottoms drilled
out, and are assembled into vertical columns that the air passes
In operation, the black painted soda pop cans are heated by the sun, warming the air that is flowing up through the cans.
A manifold at the bottom evenly distributes
room air to all the can columns, and a similar manifold at the top of
the collector collects the heated air for distribution back to the room.

Thanks very much to Greg for so care fully documenting building the collector, and for making the plans available!
