Passive solar experimenter who directly influenced Zomeworks' di-thermal wall development. Baer names him in the Cool Cell brochure's "Past Work" section (2002) alongside Harold Hay and Tim Maloney:
"Shawn Buckley introduced passive wall-modules to capture heat and coolth"
Buckley experimented with passive heaters where the south-wall collector and interior storage tank were at the same level — relying on a thermosiphon to circulate heat without a pump. His check valve was a layer of oil floating on water: sensitive but effective.
From Baer's "Work Leading Up" notes (October 2002):
"Years ago Shawn Buckley experimented with passive heaters where collector and inside tank were at the same level; he used a layer of oil on top of water to make a very sensitive fluidic check valve. Buckley advised us that it would be easier to use floating plastic check valves."
That advice — switch from oil-on-water to floating plastic balls — became the boogie valve, named by Joe Minella. The boogie valve was the mechanism for Zomeworks' di-thermal wall experiments before Baer switched to ceiling tanks in August 1999.
Buckley sits one step earlier in the Cool Cell genealogy than Maloney: Maloney is acknowledged prior art; Buckley directly fed into Zomeworks' development process.
Background, location, formal affiliation with Zomeworks, and when "years ago" was (likely 1980s–early 1990s). No patents or publications in the archive.
