i was reading through instructables and found this interesting little gizmo-
http://www.instructables.com/id/Solar-Heater/?ALLSTEPS -and i remembered a conversation with my boss this morning before i went home, and got to thinking. which would be better: having the south curtains open all day, or using a somewhat active collector like this? i have a couple of concepts to do with interior window fixtures and stuff, but im not really sure which to use, or if i should even bother. any ideas? jason _________________________________________________________________ Climb to the top of the charts!
