Abstract: Floating, Insulated, Waterless Toilet System with Fece-Urine Separation, Slippery Coating, Urine Bag, Dehumidifying Structure, Fecal Disinfection-Deodorization by Microbes, and Urine Disinfection-Deodorization by Hydrogen Peroxide includes a system of components. The Toilet Pedestal is made of a water-proof, structural foam that both floats in water and thermally insulates the Fece Bag. The feces and urine are kept separate by a ridge between the urine bowl and the fece chute. The Toilet Lid forms a temporary seal with the Toilet Platform when the lid is closed. The Toilet Lid is thermally insulated so that it stays warm and dry inside the toilet. The Toilet has a thermally conductive structure that condenses humidity inside the Toilet. The urine and condensation are collected in a Urine Bag. The surfaces of the Toilet are covered by a slippery coating to prevent feces attachment. The feces are disinfected and/or deodorized by special microbes.

Abstract: The invention provides a flush free drain trap system. The trap of the invention may be used in any trap system intended to block a back flow of odors from the waste line. A sealant liquid floats on top of the waste liquid in the trap to block odors. The trap uses one passageway to pass liquids to the sewer line, similarly to a conventional drain system, for preventing overflow and allowing cleaning. A second passageway allows the trap to dispose of small amounts of the waste liquid though an opening and a valve operated by the buoyancy caused by the accumulation of waste liquid in the trap. In normal use, waste liquid is passed to the sewer line without loss of sealant liquid. Furthermore, the performance of the trap is not affected by the evaporation of the waste liquid when the trap is unused.
