Zomeworks Vice President (12+ years) and engineer-inventor. Held three patents (Beadwall, Integral Roof Cooling Container, passive ventilation). Designed Frank's House / Beadwall in Placitas, NM (1980).
Zomeworks engineer and inventor. Held three patents relevant to the archive:
US 3,903,665 (1975) — Beadwall (“Heat energy transmission control panel”). Assigned personally (not Zomeworks). Polystyrene beads pneumatically blown between window panes. Sunspots (Ch. 6.5):
“Such elegant inventions as the beadwall indicate that the healthy response of architecture to increasing energy costs may be increased use of glass in building walls rather than a retreat to underground buildings.”
US 5,609,200 (1997) — Integral Roof Cooling Container. Assigned to Zomeworks Corp. Water-filled containers rotationally molded directly onto metal roof sections; cools by night-sky radiation; no separate support structure. Lapsed 2001 — one year before the Cool Cell brochure. Bridges the battery cabinet patents and the Cool Cell.
US 5,603,656 and US 5,660,587 (both 1997) — Passive ventilation device/system. Co-invented with Steve Baer. Hydrogen gas venting from battery cabinets using passive buoyancy.
Described in the archive as VP of Zomeworks with “12+ years with Cool Cell technology” and as a believer in the strong local Albuquerque market for passive cooling. Quoted in Baer’s 2004 “Dear Shareholders” letter: “I’ve worked with this and Cool Cell technology for over 12 years and know it is reliable and really works.” See Dear shareholders.
