Steve Baer's 1974 CoEvolution Quarterly article surveying gravity-driven heat engines and presenting his own regenerator-based 'diving engine' — a Stirling/Ericsson-adjacent design…

Whole Earth-lineage periodical that published Baer's 'Gravity Engines and the Diving Engine' in Summer 1974.

Baer's separate engineering vehicle at Zomeworks' founding, assignee of the 1969 osmotic heat pipe patent US 3,561,525.

Co-inventor with Baer of two late Zomeworks patent applications (solar thermal tube plate heat exchanger, 2007; dual-axis high-wind solar panel support, 2010), neither granted.

Movable-insulation invention (US Patent 3,903,665, Harrison, filed 1973) that blows polystyrene beads between window panes, covered by Mother Earth News in 1974.

Baer's September 2004 letter as Zomeworks president reporting the US 6,357,512 patent, a $93,000 capital raise at $3.00/share, and the roll-form franchise vision.

Zomeworks' insulated skylight louver (US Patent 3,884,414) that opens and closes by itself via refrigerant-canister weight shifts, with no electricity, thermostat, or motor.

A. & A. Iske's 1882 gravity heat-engine patent, the earliest version of the recurring bubble-wheel design Baer traced at the US Patent Office in 1973.

Baer's zonohedra structural system (zome form) patent, filed 1968 and issued 1973.

Dave Harrison's 1975 Beadwall patent ('Heat energy transmission control panel'), assigned personally rather than to Zomeworks.

Rambach/Ormat Turbines 1981 patent documenting a pure passive dual-thermosiphon loop cooling a ~2 cubic meter telecom shelter — the closest real precedent for miniature thermosipho…

1990 Battery Temperature Regulation System patent, the first in the Cool Cell lineage, which commercially proved night-sky radiative cooling in telephone-company battery cabinets.

1991 Temperature Regulating System patent adding a stratifying insulation layer to a ceiling-mounted water container — the Cool Cell ceiling reservoir concept.

1994 Passive Cooling System patent that moved the radiator to the roof with symmetric parallel conduits for balanced thermosiphon flow.

1995/1996 corrugated-roof passive temperature regulating patent mating blow-molded water containers to roll-formed metal roofing, later refined into the 2001 Cool Cell patent.

Dave Harrison's 1997 Integral Roof Cooling Container patent — water containers molded directly onto metal roof sections, cooled by night-sky radiation — bridging the battery cabine…

The 2002 Passive Heating and Cooling System patent held by Zomeworks — the Cool Cell architectural system patent underpinning the Double Play.

Baer's zonohedra-derived structural system (US Patent 3,722,153), fusing 'zone' and 'dome' — simple in structure, complicated in shape, and the form behind Zomeworks' name and the …
