According to Manchester University’s Sarah Haigh, an expert in nanotechnology, developments in the field of science of manipulating atoms in matter might prove to be the key in transforming waste water from toilets to become safe enough to drink. This scaffold device will hold a mixture of bacteria and tiny metal nano-particles, where they in turn react with the water in order to extract useful hydrogen, while the remainder will go through the filtration process again to produce clean water. I am not sure whether it is psychologically appealing to know of my water’s source, how about you?
