100_6877This is a passive solar outhouse design that we’re working on to use on our job sites.  (In the background there is an unfinished shed project.) The outhouse uses the heat of the sun to kill pathogens and evaporate water.  Inside there is a normal ceramic toilet and a holding tank of fresh water. Dual containers in the drying unit can be alternated, making disposal of the dry compost end product easy.
