I wanted to share the excellent handiwork of my friend and neighbor, Yasutaka (Taka) who owns and pilots a Cessna 182.
Summers in Phoenix are torturous for pilots, and Taka wanted something that would provide short-term cooling for ground/taxi to altitude.
Starting with the Blowbox blower/heat exchangers engine, he engineered and fabricated a lightweight console that would fit between the seats of his plane and provide cold air streams via eyeball vents for front as well as rear passengers. This console also incorporates drink holders as well as Blowbox on/off switch, stepless blower speed controller, and digital temperature and voltage readouts. Taka also built a custom lightweight remote ice chest that sits in the rear baggage area.
