Michael Pritchard, an inventor specializing in nano technology, recently demonstrated his Lifesaver personal water filter at a TEDGlobal (Technology-Entertainment-Design) talk at Oxford. He showed how his nano-pores water filter could take the absolute worst quality water, like
what is found in floods or disaster areas, and make it drinkable. The
results were extraordinary. Pritchard took water from the River Cherwell and the River Thames in Oxford and added water from his pond, sewage runoff, unidentified plant matter and rabbit poop. Then after putting the water in the portable Lifesaver water filter and pumping it maybe 3 times, it came out as perfectly good water. Pritchard then drank from it and shared it with the moderator.
Pritchard also claims that his device is available at a very low cost. He estimates that for $20 billion, personal filtration systems like the Lifesaver can give clean drinking water to all 3.5 billion people in the world who need it. Using conventional water treatment plants, this would cost tens or hundred times more. Watch the full video from the TEDGlobal conference below:
