"The obvious problem with this is that Ammonia is a terribly toxic chemical

enclosed, inhabited space is likely to result in death. Zeolite / Water
Adsorption systems, which work on more or less the same principle, are
therefore much preferred."

construction of a zeolite solar frig in return for documentation of the
effort.
