Home sweet "zome": A special "zoned home" makes life in the desert an uncompli cated pleasure for Steve and Holly Baer near Albuquerque, New Mexico (above). Well water, pumped up by windmill, fills drums arranged inside a south-facing glass wall (below). On winter days movable out side panels are lowered to expose this unique solar collector to the sun. At night, with panels raised, the stored heat warms the house by radiation and convection. The panels are closed during the summer.
