In April of 1999 there was a short thread running on protecting lenses
from fungus. Doris Fang briefly described Kodak's design for a
"Tropical Cabinet" which was a closed cabinet with ventilated shelving
heated with incandescent light bulbs. The idea was that the light
bulbs raised the temperature in the cabinet above the ambient and thus
reduced the relative humidity level.
Today I went looking for plans for such a cabinet; first on Kodak's
site and then a much broader search on Google. I found lots of hits
regarding humidity controlled "dry cabinets" or sealed containers
using a dessicant but didn't find anything like what Doris had
described.
Anybody have any more specific detail on the design of the "Tropical
Cabinet"

My memory of Doris' message was that Kodak provided a construction
plan. I don't know whether it was in a book or available separately.
She either built it or had it made to the Kodak instructions. She said
it was vented at the top and bottom and the incandescent lamp used for
the heater was in the bottom to provide convection warm air circulation.
