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. This amazing demo from TEDGlobal in 2009 shares this life saving invention.
With cutting-edge nanotech, Michael Pritchard’s Lifesaver water-purification bottle could revolutionize water-delivery systems in disaster-stricken areas around the globe. During the twin tragedies of the Asian tsunami and Hurricane Katrina, Ipswich water-treatment expert Michael Pritchard winced helplessly at televised coverage of throngs of refugees waiting for days for a simple drink of clean water. Stricken by the chronic failure of aid agencies to surmount this basic challenge, Pritchard decided to do something about it.
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.
LIFESAVER bottle is the world's first all in one ultra filtration water bottle. It will remove bacteria, viruses, parasites, fungi and all other microbiological waterborne pathogens without using chemicals like iodine or chlorine which leave a distinctive foul taste. LIFESAVER bottle produces filtered sterile drinking water quickly and easily. With LIFESAVER bottle there is no need for tablets, boiling, chemicals, tubes, shaking, scrubbing, waiting or effort. LIFESAVER bottle produces clean, sterile drinking water with no foul taste - fast! Simply Scoop and Go, give it a few pumps and that's it, as soon as you open the teat clean drinking water begins to flow.
