Dear Mr. Jenkins,
I designed a public domain / open source refugee shelter system
called the Hexayurt, which also specifies a composting toilet
(specifically a thermophillic system) as the most likely long term
solution to sanitation needs for refugees and the global poor.
Due to an absurd series of coincidences, I'm involved in a project
called TIDES - http://www.ndu.edu/ctnsp/whatsnew.html - or http://star-tides.net - which is turning into kind of technology show case
for appropriate technology for disaster relief.
Can you help us get the message about thermophilic toilets across?
