Separating Toilet

Basics

A modern flush toilet that seperates urine from feces for use in applications (such as composting toilets, or biodigesters) where a urine-feces mix could lead to unbalances of chemicals. This innovation allows for the use of a regular flush toilet, and converting it to a separating toiled without any modification of the toilet - but only the plumbing below. This allows the use of a standard $100 toilet to achieve the separation function - instead of using a specialized $1000 separating toilet.
