Hi, I just recalled an article that was in a Rodale Press monthly publication that was a passive refrigerator, ice box to be accurate, project. As I recall it had a refrigerant loop with the condenser outside the building under the shaded eaves of theroof and the evaporator an insulated box with water in a partition. I believe over time the passive unit was supposed to freeze the water into ice. Problem is I can't remember the name of the magazine to even begin a search. Doug
