if you google mother earth news and go into their web site archives, there is a very simple solar air window unit similar to the soda can one, but you don't have to use the cans - you can use old panes of windows and simply build a 2x4 frame and add black paint.
go take a look, i'm going to try it this winter in my second smaller coop to measure performance.
Update: it's like this one: Heat Grabber see MOTHER EARTH NEWS EDITION NO. 47, page 101
