Image caption (from article metadata)
The diagram shows a mockup of the beadwall insulated window panels. The beads are fed in through the top from the storage drums then they are needed and drained from the bottom when they aren’t.
This confirms the storage drum mechanism: beads are stored in drums adjacent to the window, blown in through the top when insulation is needed (night), drained from the bottom when solar collection is wanted (day).
Context
Published September 1974 — six months before Sunspots (June 1975), making this the earliest known published description of the Beadwall. The Mother Earth News audience was the counterculture/self-sufficiency readership aligned with the Whole Earth Catalog network — the same network as Baer’s other mid-1970s publications (Coevolution Quarterly, Summer 1974).
Sunspots (section 6.5) credits the Beadwall invention to Dave Harrison and notes “patent applied for.” The MEN article was written by Baer himself, suggesting he was the public face for Zomeworks’ products even when Harrison was the primary inventor.
