Jeff beat me to it. I've lent a paper copy of Jenkins' book to a dozen people. All were skeptical (as was I), now hold graduate degrees (whatever that's worth), and accepted the practicality and safety of Jenkins' system after reading the book. Four of the twelve have put the system to practise.

I may or may not have used the composting toilet system described in Jenkins' book for the last four years. The possible experience may have led me to the conclusion that the system described is simple, cheap, nearly fool-proof, and except for a few minutes while dumping buckets into the compost bin, stink-free. No need to seperate liquids from solids either. Just do your business and cover with a scoop or two of sawdust.

I may or may not have experience with the syste, but my wife most certainly has not (but she's fine with a commercial composting toilet that is in the works for the house we're building).
