This is a picture Fred sent in showing his set of solar shop heating doors.
Very nice work!
Here is a better picture of Fred's solar doors: Fred is willing to answer questions on the doors or provide more information. Email me, and I will pass any questions on to Fred -- email me at: Gary... Be sure to make in clear which project you have a question on! Thanks very much to Fred and Gerry for sending this in!
