This is one of the most incredible things I have ever seen.
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?
|
Probably Politics. more confusing then starcraft
|
I don't know, it's not really amazing. The bigger problem is educating people about this stuff and the logistics around it. There are already TONS of ways to cheaply clean water, and I mean actually cheap. This stuff will cost a gigantic fortune in comparison.
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.
|
I guess the real problem is that any nation that can mass produce these already has for the most part clean water. Nations that would really need these can't afford them, and no one giving away anything for free.

im a noob when it comes to survival, but doesn't boiling water cleanse it?

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.

Safe drinking water for all for only 20 billion? Where you at bill gates??
|
i watched some movie in like 6th grade once that showed how to get clean drinking water by using a plastic sheet to collect the evaporating water and have it trickle into cups. it seemed pretty useful and probably the only reason i still remember it.

boiling it kills the bacteria but it doesn't get rid of elements and pollutants like arsenic or mercury which tend to be in water
GL getting electricity to a place that don't even got pure water...
lol

@Klockan3 -- you don't need electricity to boil water 0_o
@FragKrag -- is chemically poisoned water a problem in 3rd world countries? or is it mainly bacteria and things that boiling water would actually kill?

well in places like India and china probably, but in Africa it probably isn't as bad as the malaria and parasites
though boiling the water and condensing the vapor back into a liquid works too

I doubt it is merely politics. It is still just a niche use. 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.

Might be nice as a prophylactic in areas frequently visited by disaster, though.

What is the secret behind this revolutionary technology that filters out EVERYTHING and is extremely cheap, and lasts for a very long time? This seems fishy to me.

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?"

Isn't the Brita filter just a bunch of active carbon ????

Not really news. Singapore has been doing this for years on a large scale.
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.

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.

The issue with water is actually not drinkable or not. 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.
|
This would be cool if they did mass produce it. Hopefully they are able to get this to third world countries either way to help out.
|
MK, most filters used activated charcoal in their filters. That's a very basic filter. My Brita filter uses activated charcoal and something sandy.

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.

Water's really heavy. It's really expensive to ship in that much water. 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.

water "crisis"?
people dont care unless they start dying from it, and when they do start dying nobody cares because they are already dead

some people don't die from drinking water that isn't purified, they just get really sick. 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.

2 drops of iodine into flask... gg safe water... tastes like shit but its safe... this is how the hardcore secret navy seal bad ass people do it 
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

Not to mention some of those places don't really have the resources to create a fire. The big deal with teh Sudan conflict is that people were pushed into these refugee camps where they have to dangerously stray into enemy territory to get firewood.

Africa doesn't have the infrastructure to support pollutants just yet....Wait till they get to that stage, water will be a MAJOR issue. 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.

I meant "portable", as in you can move the purifier around =)
Fremen stillsuit, as in the stuff they wear in Dune. Recycles sweat, shit and piss into drinkable water =)
