¶ Double Play Installation — Photos
Two photographs documenting a Double Play thermosiphon installation, likely related to the Steve Baer Double Play Thermosiphon — Kayatekin project. The images show both the interior hydronic ceiling panel assembly and the exterior building with south-wall thermal absorbers.
¶ Interior — Hydronic Ceiling Panels
Looking up at the Double Play ceiling panel system from inside. Dark (likely black-painted) corrugated metal ceiling panels serve as both radiant ceiling and thermal mass — they absorb solar heat or reject it to the night sky depending on the season. White PVC or copper hydronic pipes run across the underside, carrying fluid between the ceiling panels and storage. Brass compression fittings are visible at pipe junctions. A CFL pendant light hangs from the center. An "ARTlines" poster is partially visible on the back wall, placing this in a gallery or studio context.
¶ Exterior — Shipping Container with South-Wall Absorbers
A converted shipping container building with black thermal absorber panels covering the south-facing wall. The absorbers — likely unglazed pool-style collectors — are used in the Double Play configuration to both collect heat in winter and radiate heat to the night sky for cooling in summer. The white metal roof is the exterior surface of the Double Play radiant ceiling seen in the interior photo. The New Mexico desert scrub and suburban background are consistent with the Albuquerque area.
