Inventor and founder of One Design Inc. Developed rotationally-molded water-wall modules for passive heating and cooling in the late 1970s–early 1980s. Baer names him explicitly in the Cool Cell brochure's "Past Work" section (2002), alongside Harold Hay and Shawn Buckley, as a direct predecessor:
"Shawn Buckley introduced passive wall-modules to capture heat and coolth; Harold Hay used roof-ponds; Tim Maloney used rotational-molded water-walls."
| Patent | Title | Key tech |
|---|---|---|
| US 4,257,477 (1981) | Environmentally driven heating and cooling system | Water containers behind south-facing glazing; spray-cooled for summer; field-erectable modules |
| US 4,263,765 (1981) | High mass wall module | Concrete-fill or massive-fill modular wall blocks stacked to make walls |
| US 4,290,416 (1981) | Phase change energy storage panel | Glauber's salt containers behind south glazing; pivotally mounted for reversibility |
| US 4,355,682 (1982) | Environmentally driven heating and cooling system | Continuation/refinement of US 4,257,477 |
The phrase "rotational-molded" is significant: Harrison's integral roof cooling container (US 5,609,200, 1997) used the same manufacturing method on roof sections. Maloney was doing it on walls ~15 years earlier.
Location, biography, and whether Maloney and Baer had direct contact are not in the archive. One Design Inc's fate is unknown.
