Turning filthy water drinkable: Michael Pritchard on TED.com

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 turn the most revolting water drinkable in seconds. An amazing demo from TEDGlobal 2009. (Recorded at TEDGlobal 2009, July 2009 in Oxford, UK. Duration: 09:32)
