Abbott Posted August 9, 2008 Share Posted August 9, 2008 There's a reason they call it the "Lifesaver." On the outside, it looks like an ordinary sports bottle. On the inside, there's a miracle: an extremely advanced filtration system that makes murky water filled with deadly viruses and bacteria completely clean in just seconds. The Lifesaver removes 99.999 percent of water-borne pathogens and reduces heavy metals like lead, meaning even the filthiest water can be cleaned — immediately. It will be a boon to soldiers in the field, so it's winning accolades from the military. It also stands to revolutionize humanitarian aid. It could be the first weapon in the fight against disease after a natural disaster, like the one in Myanmar this week. I attended the Lifesaver’s launch at DSEi London, the world’s largest arms fair. Its inventor provided a pool of dirty pond water as a test subject, and I drank some after it was filtered. Not only did it look pure once it passed through the Lifesaver, it tasted pure, too. The process takes only 20 seconds and is simple enough: scoop some water, pump it through the filter and you’re ready to go. The instructions are displayed in pictures on the side of the bottle, so it can be used by anyone, removing the language barrier. Outdoor enthusiasts may find it useful, but the Lifesaver is perfect for the military. The bottle is designed to “scoop and go,” so soldiers won’t have to carry the added weight of clean bottled water. They can pick some up out of any source and keep moving. As an added bonus, the bottle can shoot a pressurized jet of water from any angle, which will be useful for washing wounds free of contaminants and debris. Other filters use ceramic pores and can’t catch most bacteria and viruses, but the Lifesaver uses microscopic pores a mere 15 nanometers across — about one-hundredth the width of a spider’s silk — narrow enough to stop the tiniest threats. That means virtually nothing — not even bacteria and viruses — can get through. And since the bottle uses a carbon filter, it makes water safe and sterile without any chemicals, removing that iodine or chlorine taste. The bottle weighs about 1.5 pounds and can filter one and a half pints of clean drinking water each go. Its replaceable filter can handle more than 1,500 gallons of dirty water before it has to be replaced. And since it won’t process any water once the filter has expired, it will be impossible to drink contaminated water by mistake. Michael Pritchard, a British entrepreneur, designed the Lifesaver in the wake of freshwater shortages that followed the 2004 tsunami and Hurricane Katrina. Delivering bottled water to disaster areas is difficult, especially in places like Myanmar, where the government is currently interfering with efforts to distribute supplies and aid. If disaster victims had access to the Lifesaver, they could have ongoing access to clean water without the need for airlifts. Delivering those planeloads of water is expensive, too. A U.S. Army study revealed that the cost of delivering bottled water to Afghanistan was $4.69 per gallon. Pentagon figures on Hurricane Mitch showed the cost of air freight was even higher: $7.60 per gallon. Just one Boeing C-17 transport plane full of Lifesaver bottles would provide 500,000 people with access to safe drinking water for up to 16 months — saving millions and saving lives.

John Kettler Posted August 9, 2008 Share Posted August 9, 2008 Abbott, Very cool! If it'll greatly reduce lead in water, that could be quite a boon if facing--DU! Some years ago, I was seriously looking at the Filtrete(?), a special filtered straw, as another way to get there from here, but this seems a far better solution. Got to love those special British Empire sales awards, like the one given to the firm that, so help me, sold sand to the Arabs! Mind, it was a very special fine sand for filters, but still.

Elmar Bijlsma Posted August 9, 2008 Share Posted August 9, 2008 Huh, pretty cool stuff. If it can be made relatively cheaply it's a license to print money. I had no idea tech was so far advanced on this. 0 Quote Link to comment Share on other sites More sharing options...
Michael Emrys Posted August 9, 2008 Share Posted August 9, 2008 There have been hand pumped filtration systems for hikers and campers for about 20 years now. These were brought out after the big giardia scare. Michael 0 Quote Link to comment Share on other sites More sharing options...
easy-v Posted August 9, 2008 Share Posted August 9, 2008 Only $230-$300 a pop. The only difference I can tell is that this one filters to 3 decimal places: 99.999% of bad microorganisms. Would it also filter out gasoline, oil, fertilizer, feces? 0 Quote Link to comment Share on other sites More sharing options...
Elmar Bijlsma Posted August 9, 2008 Share Posted August 9, 2008 It's not just that it is, if the report can be credited, very good. The ease of use seems better then any system I've ever seen. That's a big plus when distributing water to ignorant villagers and Marines. 0 Quote Link to comment Share on other sites More sharing options...
flamingknives Posted August 9, 2008 Share Posted August 9, 2008 At 15 nanometre pore size, there's nothing that isn't a molecular fluid and similar viscosity to water getting through. 0 Quote Link to comment Share on other sites More sharing options...
Sombra Posted August 12, 2008 Share Posted August 12, 2008 Only $230-$300 a pop. Would it also filter out gasoline, oil, fertilizer I dont think you can filter out other liquides etc. But is good against microorganism. 0 Quote Link to comment Share on other sites More sharing options...
