http://www.ted.com/talks/michael_pritchard_invents_a_water_filter.html The solution to one of the most important problems is revealed, yet politics will sadly get in its way. Definitely makes me think the next time I fill up a glass of water. The guys is inspiring. How is it, that our world is complex enough that these bottles aren't mass produced and delivered NOW? | ||

Like SODIS. Disinfect your water with the sun and some plastic bottles. Recommended by the WHO and used by millions around the world. The truth is that those people don't need some 15 nanometer hole bullshit expensive water filter, they just need acceptable drinking water and there are already better ways to get that. | ||

@FragKrag -- is chemically poisoned water a problem in 3rd world countries? or is it mainly bacteria and things that boiling water would actually kill? | ||

I think it's a great idea for disaster areas where you probably have freshwater sources... its just dirty no? I think it's a great solution for conflict areas of the world. Even then, how much would it cost to produce and ship to every one who might be able to use it? How much would it cost to produce these filters and keep them stocked for everyone? If it's a disaster area or a conflict area, how do you get these to the people who need them? Though its pretty cool that it can filter your pee a couple times over. He's pretty specific about the cost of getting the filters to "everyone," though perhaps not so clear on a timetable. As far as using the filter to relieve disaster areas, it would probably be just as easy or easier to fly in water, seeing as how the main problem is gathering and transporting resources to the affected area and the solutions only need to last for a relatively short period of time. Might be nice as a prophylactic in areas frequently visited by disaster, though. | ||

He also gave one of the funniest TED talks ever. He was on the topic of malaria and brought a jar of mosquitoes with him. He released them halfway through the talk going "why should only poor people have to experience this?"  | ||

http://en.wikipedia.org/wiki/NEWater We recycle sewage into drinkable water. The country is like a massive Fremen stillsuit. We also donate portable water purifiers to third world countries. For places where there is no water source at all, one of our companies has a machine called the Dragonfly which condenses water from the air ala Dune. | ||

This seems fishy to me. the secret to the filtering out EVERYTHING is he managed to make the holes 15nm in diameter as opposed to the 200nm wide holes in previous filters. This is significant because according to the video the smallest virus is 25nm wide ( polio virus), and thus his filers are 1337. | ||

Our global water ressource is used much more for agriculture than for drink. It's good to filter and make it drinkable but it doesn't solve the problem of the lack of water for the agriculture. I ain't sure about the number but it's like 60%+ water are used for agriculture and 1% for drink (someone check ?), especially in poor countries. PS : the Show "The Colony", they made a filter with charcoal and sand. | ||

That wasn't really what I meant... we already have had filters that can filter out virtually everything but it's like 100 dollars and doesn't last that long. How does he make them so cost effective and long-lasting? | ||

Ted is for sure a great show but I think we should all stay skeptical or at least critical. For example, I'm still not convinced about the link between global warming and Human activities. The guys speaking at Ted are for sure the best talkers in the world but it doesn't mean they are right. They "think different" which is a great thing and I truely believe it's important to have multiple points of view but don't rush to the conclusion because someone said something. I ain't rocket scientist, I'm just a lame pure math bachelor wanking in a regular random business school but I'm sure that if everyone starts to check and open their critical mind after watching Ted, the world will sure become better. I don't feel bad or even worse after watching a Ted, I just feel that maybe, I have to check if the solution and the facts these guys are talking about are true or false. And I guess this is the real beauty of Ted : make us think, make us check, make us skeptical or critical. | ||

Seems like it'll be cheaper to ship in a bunch of really light plastic bottles than it is to ship in several times more plastic bottles with water in it. | ||

To stop them from getting sick and generally improving the health in that area is always a good thing. I suggest watching some Hans Rosling videos on ted.com as they show a good amount of stats about the world. | ||

12 drops per gallon. doesn't this seem a lot more cost efficient... how much is a bottle of iodine? edit-- and boiling water does not sterilize it... definitely helps but there are strains of bacteria that are resistant to boiling | ||

One of the largest continents in the world becoming a developing country with cheap labour and a massive burst of industry will absolutely destroy the air quality and the water quality in the area.
