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. | ||

Watch anything on TV-shop and you will get the same thought. Till you slap yourself and realize that they never tell you the whole story, if he sold bottles for 20 billion he would become one of the richest man on earth which is why he talks so warmly about it.

@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?"  | ||

This seems fishy to me. It's fucking expensive. It also does the same thing as your brita filter, just with smaller holes. | ||
