Cranfield University is developing the Nano Membrane Toilet which will be able to treat human waste on-site without external energy or water. The toilet is designed for single-household use (equivalent to 10 people) and will accept urine and faeces as a mixture. The toilet flush uses a unique rotating mechanism to transport the mixture into the toilet without demanding water whilst simultaneously blocking odour and the user’s view of the waste. It has been described as "a household scale off-grid toilet which produces clean water and ash." and it's a " power-generating ‘super-toilet’ that doesn’t need mains water and can charge your phone. The unique nanostructured membrane wall facilitates water transport in the vapour state rather than as a liquid state which yields high rejection of pathogens and some odorous volatile compounds. On Gizmag they describe this as "a cheap waterless toilet that turns waste into clean water and power.
