AKA turd toasters for remote Alaska radomes where the flush wasn't an option. Now, this is available #sehar post a reply when you stop laughing.
I remember the "Old" Alaska out houses were Propane or Natural Gas powered, all you had to worry about was dumping the ash and keeping the fuel tanks up!
Interesting... Could be handy when no way of disposing of sewage. I wonder what it is using propane, butane, natural gas or is the paper something special.
Some RV manufacturers are experimenting with these. You effectively do away with a black tank and just have to worry about your gray water.
