Description

Full title: Michael Pritchard's water filter turns filthy water drinkable
Too much of the world lacks access to clean drinking water. Engineer Michael Pritchard did something about it -- inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. An amazing demo from TEDGlobal 2009.
Using a non-chemical nano-filtration hollow fiber membrane with 15 nanometer pores (it is designed to block viruses), the Lifesaver bottle can make the most revolting swamp water drinkable in seconds. Better still, a single long-lasting filter can clean 6,000 liters of water. Given the astronomical cost of shipping water to disaster areas, Pritchard's Lifesaver bottle could turn traditional aid models on their heads.
