A new view on cleaning water

Fresh, clean, drinkable water is an increasingly rare thing on this planet, especially in places that are suffering through catastrophes like floods or must deal with high levels of pollution without the resources to set up water treatment facilities. But a project from Stanford University researchers could see cheap, simple filtration devices distributed through developing nations. How simple? Well, it’s just a piece of cotton cloth coated in nanotubes that filter out nearly all bacteria at a rate faster than other filtration methods…
