That demonstration reminds me of the old days when a traveling sales man would come to your house with a vacuum cleaner and start putting dirt, and other stuff no one wants on their carpets, and then show how great the vacuum cleaner is.
This happened to me and my Mother when I was around 5, the guy starts pouring dirt on our floor, I am looking at my Mom, like this is insane, the guy was really nice, but his vacuum didn't work, the carpet was a mess, and all we could do is laugh.
All jokes aside, this looks great, I wonder how long it would last in the conditions the experiment was done, I would think that those small pores would clog up kinda fast and it wouldn't be efficient if you need to change the filter often, I don't see how you can clean it, but I have never built anything quite like this.
If you give a man a Life Saver bottle, he'll drink 6000 liters of water, but if you teach a man to filter his own water, he'll drink for a lifetime.
Luv that philosophy. Sounds very similar to learning how to fish.
But the much cheaper life straw could do the gap measure trick
The life straw is just a basic water filter that blocks bacteria and some cysts and lets in deadly viruses. Over time [weeks] the life straw which only blocks bacteria and some cysts has a dangerous level of bacteria growth within the straw as the blocked bacteria massively multiply. A life straw is really only a single use water filter and should not be used in my opinion over several days. There's a reason why it's cheap to buy
rayva1 and also getting to heaven, or something like that
thats an epic quote bro
After watching this video I looked at the year - 2009.. So I thought to myself, "Wow, that was 5-6 years ago. I wonder why I haven't seen this all over the world?" Then I went on google and searched for where I could get a bottle. I found my answer - the bottle costs $163.00 !!!!! For poor Africans facing water shortage and contamination, it might as well be $1 million. R U KIDDING? If he really cared, he would sell them for a cost that is more affordable. You cannot tell me that this costs $80 to make per bottle! I hate greed. There are so many world problems that could be saved it if weren't for greed. And for all those that have flamed me, you miss the point. I am not talking about what it costs me. I buy expensive survival gear all the time. But seems to me this is more like the drug companies selling pills for crazy profit just because they know you need it. Glad there are church groups and other organizations donating time, talents and materials to provide as many communities as possible, safe drinking water. Be an entrepreneur, but don't prop up the poor and needy to make it seem like you care, cause if you did, you would be doing something way more impactful.
At 160 a pop it is expensive. Yes I can dish out that money in case of dire need but then damn it, not everyone wants to go buy it on disaster day. So mass produce it and lower the freaking cost!!!!
Dax Castro Based on their website, the small one (that can filter 4000 liters) costs 120 pounds. Based on 3 liters/day water consumption, you get an approx. 3.65 years, which is 0.09 pounds per day, or 2.7 a month, or 32 / year. That doesn't seem that expensive... The only problem I see is that in places where they'd need this bottle 163 at once is expensive, but there NGOs could step in and come with some payment plans or subsidies for bottles.
Right
plus, for a purchased bottle they give one away for free for families in need
I know I agree this is too much money just to to vat19 they have the same thing but a straw and portable but I bet you can get a water bottle and drill a bigger hole....also vat19 give 1-10 life savers to countries developing and it didn't cost much like around 10-20$
Sawyer water filters connect to standard water bottles (Dasani etc). They have a 200k gallon life, they filter down to 100 nanometers/0.1 micron. Cost $22 USD each, $58.47 for 4 pack today 05.20.22.
Extremely light weight, I've been using them for years hiking in the Appalachian mountains. These have become a don't go without them item when I hike. A must have for home/auto emergency kits as well.
Maybe electric car batteries will see a similar price decline over the next decade?
too bad the price is outstanding, and people who could really use technology like this will never be able to afford it.
Because it’s not for us
Look at the crowd that a tell it’s not for us
Half a cent a day per person have you seen what world governments spend on defense
Solution is there nirnal
This is a great product for emergency water consumption in devastated areas and for survival, but not regular use.
Simple and direct to the point and with sincere intent...
Just went onto amazon. Its US$135 in 2019
This video is cruel to the poor people it claims to help
I agree Zubair Khan. Very disappointing. Just another water filter for the middle class and up.
@@cheryldahl9192 yes, it seems that way. A marketing pan based upon peoples emotions to bring this product into mainstream outdoors folks. It was 9 years ago, today 30 seconds ago it is 137 Euros to buy off Amazon. Impossible to implement this on such large scales effectively. It's cheaper to fly in water. UNLESS, the technology costs/profits reduced greatly. I worked many years as a research scientist and one of the biggest issues is how to make effective filters at low cost. it appears it still hasn't been achieved.
@@BushCampingTools Sawyer mini filter is 0.1 microns, 26$, filters up to 100000 gallons of water :S Granted filter is 0.1 micron not 0.015, but just boil water after to kill viruses
Way cheaper.
The smaller the membrane the more advanced in technology you go. 0.015 is incredibly small, but now there are similar filters for example the survivor filter pro on amazon.
These types of filters could be sent in some form of charity to the countries in need as well. I'm looking into a portable distiller myself that got me here.
Anyways good stuff
@@r0l3kr0l3k kind of misses the point , if you have to boil it
sounds like an awesome invention but it also sounds like a sales pitch asking the UK to buy his product for 8 billion dollars.
Nothing wrong with that
Pretty much. I'm on the fence with this one. It's a money saving solution. He should get paid for his effort. I hope he put in the effort the get governments to implement it or similar invention that's larger scale. IF he does that much work, THEN he should get paid & (in an ideal world) throw half of his $ into the project.
I would want to make something the the hard innovative work. It looks like a great invention to help people. But, I can't see any government buying this product. Why pay for it if they can just kick your door in and take. Or tell everyone to not back up his idea. Till he's broke and sells the government the Patten for nickles and dimes. Then will only supply there soldiers with this product.
@@sab_1055 Believe this. His profit is included in the price. He will be a billionaire before its over from this invention.
It also seems like a pretty good deal.
OR!!! You could just make, ship, and educate people on how to make charcoal/sand material water filters. Which can be made from almost any container, and can be connected in series to make water clean enough, that if it isn't drinkable at that point, is still clean enough to decrease the chances of illness, and a quick boil can take of the rest. Still more feasible then this bottle in terms of reaching the masses.
cant set that up in the 3 days between a hurricane hitting and you dying of dehydration
Most would use this method paired by solar heating for boiling & UV Light for bacteria & viruses..
Absolutely true, and there are MANY resources online and in print that do just that! So, how is anyone "hurt" by this? If you don't want what he's selling... don't buy it!
@@azteacher26 what
@@silverfoenix Solar heating? UV light? Are you forgetting the part about the catastrophic natural disaster destroying all available resources?
"Ah, yes. Decent idea, but I think most folks would just go ahead and run their water through a treatment facility first."
Real big brain, over here.🙄
it is a very basic and avaible and helpful and profitble solution.
I am watching this video in 2021. Still it is useful for such content.
It doesn't filter molecules, so it won't taste pure. And chemical contamination is still a health issue.
Which is why we should ALL learn how to "make" our own distilled water! It's virtually "free" (after you make your gizmo to do it)!
@@drileydriley2814 Anyone can make a distiller at home, just have a container that directs water vapor from a hot place to a cool place. Like a retort or even a large cooking pot with a smaller pot hung inside. Then just put it over a stove or a fire or something. Not super-easy, but not exactly hard. The problem is it takes a lot of energy to boil water, so at most you'll be making a cup of distillled water an hour. Because of water's heat of vaporization distillation isn't very practical on a small scale where you can't recycle the energy. So the problem is exactly the opposite. Distillation is easy and doesn't require expensive "gizmos", but it takes a huge amount of energy to do in amounts large enough to drink.
@@vladimirkuklev6051 ikniw its 3 years but...yes well said its very inefficient .. ive seen survival guys using a clear polythene sheet in a domed tent shape over a water container in the sun. Water evaporates and collects on underside of polythene then runs down into the clean water container.
the best water filtration system is the Alexapure Pro Water Filtration System. Sadly it is for home or Cabin use. Reduces up to 99.9999% of 206 contaminants, targeting..... Heavy Metals, Fluoride, Chlorine, Viruses & bacteria, Pesticides & Pharmaceuticals. I have searched high and low to find a portable system that even comes close. I ended up with 2 portable systems that covered some of those bases.
@@noragriffin6432 shut up
Wonderful. I think Michael Pritchard deserves the Nobel Prize for this invention. Truly amazing and in my opinion one of the most important new inventions of the millenium. I can't believe I have not heard about him before.
I am replying to old comments making sure everyone is doing well :)
@@RyanBentz Thank you for making sure we are all doing well, Ryan. Luckily I'm still alive and I feel blessed. How are you doing? Is everything well? I must have had a guardian angel the moment the accident occurred. So right now I'm just really grateful. The stolen 80.000 Colonnes, I mean that is only about a hundred dollars, and also the lens that is gone now, this all feels like nothing in comparison. The long discussion last night on the plane (wow, I mean talk about synchronicity! How is this even possible!!!) while the others tried to sleep was just amazing and absolutely invaluable!! So it is almost like yesterday alone compensated for all the problems, pain, losses and dangers from the trip.
To Justin Your thinking is right on. I believe this person is truly trying to help the world and I’m thankful for the effort he has put into creating this product. Clean water will continue to become more scarce and people here aren’t doing the simple math. So much cheaper and better for our environment than shipping plastic bottles.
So the LIFESAVER ultra endurance costs $450. Those poor starving African children must be RICH!
I know! this guy is a joke, trying to make money from the poor!
A pre filter ultraviolet system would be a much cheaper alternative, but the funding comes from foreign aid.
i doubt he has much manufacturing involved, so its possible that he needs to make it pricy to make a profit. also read what Abbas Miah said, the government can afford it, and would likely save money.
BRUH It costs to produce these things and no the kids won't buy it they'll come in form of humantarian aid ..
kitsurubami we spend more on defense contracts and arms deals!
I believe this product was designed firsthand to be used as a catastrophe aid. (A better alternative to regular water shipping to catasrophe zones.)
I watched this man talk about this when i was a kid. I thought id never see another advert asking the working class to donate their money to 3rd world contries for filtered water because this man single handedly solved the problem. He should be a multimillionaire. And we shouldn't be hearing about water problems today.
Well done this man.
VERY CLEVER INVENTION TED, , we need those even in parts of New Zealand.
Thank you TED for bringing forward this idea
I do agree it is an amazing to have drinkable water at your doorstep and more so if there isn't any on hand
. However, I'd like to know how this is an achievable idea, would you be able to release the information regarding the "simple technology" is needed to make this viable?
For someone that wanted to solve a world problem by getting clean water to everyone, why then are you asking $140+ per bottle! and $310 per can? That is outrageous! I pay less for city water! call me when you get the price of the bottle down to $20.00 and filters down to about $20 and i will buy a few hundred and have them shipped overseas to individuals that do not have city water.
Well, isn't this video from 7 years ago. That might be the reason why it is/was so expensive.
LMAO it's actually 200 Australian Dollars right now on EBAY, what a rip off.
TheHGCGamersClub where to buy the far ??
I was thinking when did TED talks become a platform to sales pitch? ... maybe i don't watch these enough
I wouldn't go by the price of comparatively small number sports bottles sold in developed countries. You would have to understand and explain his plan for solution for a different product at a much larger scale for the 100's of millions globally that need a similar product. Anyone know what Michael Pritchard's plans for this need and scale?
Very nice video. Thanks.
Great work guys i really enjoyed this episode
This man has made my dream come true, in such a simple way!
I am replying to old comments making sure everyone is doing well :)
@@RyanBentz obviously shes not responding after 7 months so shes probably not doing well
I am from BANGLADESH. Even though I don't live in a flood-prone area but many people in Bangladesh do. The video is probably a decade old now but I have never seen nor heard about this device ever in Bangladesh. As far as I know, In flood-prone areas of Bangladesh, people typically boil the water or use tube walls to get drinkable water. However, Water-borne diseases are not that common in Bangladesh, since medicine is readily available everywhere and cheap to purchase. This is because we manufacture 99% of our own medicine.
What are tube walls?
Great talk on water filtration
Great job
$160 for the filter bottle ÷1,600 gallon lifespan = 10¢ a gallon. Bottled water at my local grocery store is $1/gallon, or 25¢ a gallon at water filtration kiosks and you provide your own containers. This is a very reasonable price, especially when you factor in the fact that, in many cases, travel and transport are drastically reduced or eliminated.
He spoke everything except what's inside the bottle!
I love this video I want to try one. And see what my water at my pond looks like.
If these are the ones from kickstarter I have the very first ones put out. So glad I could help get this off the ground. I habe not used them much I'm saving them for when I have to have them
Thanks ever so much for caring.
Whether this is a financially accessible product for all who would need it ... is not the point ... this man actually tried to come up with a solution ... so ... I think he deserves some sort of recognition for his efforts. Besides, who is to say that the production of this product would cost governments the same amount of money? I think this could be a wonderful opportunity for mass production of various separate parts that make up this bottle ... so all one has to do is fit it together ... and the other is that once it has reached its lifespan ... spare parts would be readily available to replace the used parts ...
who can afford a $200 bottle what Africa needs is proper water mangement and water resources, like an electric pump and a simple filter and assign a place for livestock to drink.
What they need it to stop having so many kids beyond their capacity to feed themselves. Within the next 50 years they are projected to outnumber asia.
+Æon Bloodfang
That too, but is far more difficult than water management. Is a demographics problem it can't be fixed.
There are a lot of components to survival.
One resource I discovered that successfully combines these is the Marla survive system
(google it if you're interested) without a doubt the most useful survival resource that I've seen.
look at the extraordinary free video.
education solves both of those problems.

I suppose we can all rename YOU (P-H-P) to: "I'm envious someone else has come up with a legitimate solution to help those legitimately in need;" I'll call you Kelly for short... as in "kelly green" with envy!
@@drileydriley2814 You're right but sadly this guy in the vid just wants money nothing else. He is ripping the poor off. No one that's poor can afford it. They will still die due to how expensive the price is to get one. Atleast $100+
@@namsukeichinose I'm confused. How can he TAKE something someone doesn't GIVE him? You see, the "free market system" which so many have to hate (with absolutely NO legitimate reason) is all about one's CHOICE(s)! The ONLY time a progressive is FOR so-called "choice" is when it involves the systematic murder of they who cannot speak for themselves! Yet, when it comes to ACTUAL CHOICE, ...mum's the word! If YOU don't want to BUY what someone is selling, don't buy it. "Caveat Emptor" has ALWAYS been the "phrase of the day" for anyone in the market!
If your "point" is that he NEEDS to make the price more affordable... that's the BEAUTY of the free market! Someone WILL make something like this in the near future, and charge just a fraction of the cost he's charging! That's called "competition," and it's a GLORIOUS thing for We the People. (And, I don't mean the type of "competition" like the communication and TV reception/Internet Service Providers have colluded to give the appearance of for we, the unpowerful! "Anti-trust," anyone?)
Smart inventor desires big cash
Little disappointed at TED for letting this infomercial style sales pitch grace their stage.
This product can literally save lives. I'm completely fine with this. For instance, I live in florida.. We just went through a category 4 hurricane. We did not have electricity or water. In grocery stores, the water went off the shelves in short matter of time. This product, would be a godsend if we were unable to get clean water. Thankfully I now know about this product and will be buying some just in case.
Chris M Hey man, I'm sorry to hear that. I hope everyone you know is ok. Tell me if bought the product and if like it ?
u must have lived on the coast cause we didn't even lose power.
Deceivingly Charming I think the user was talking about how the speaker was discussing its use in developing countries. For individuals who live in developing countries, such as myself, the cost to buy one bottle is more than I can afford. It's ironic that this bottle is developed to target people from developing countries when only the rich can afford them. I think rather than the speaker talk about developing nations and the problems with water that we go through, he skip the whole portion and only discuss disaster relief in first world countries where people like yourself can actually afford his products.
teds been corrupted
Awesomely wonderful
good job
this is a blistering talk. as an engineer one of my goals is to take smart and cheap technology to the developing world, to reduce the disparity. absolutely inspirational. technology that is really benefiting others!
To think for a fraction of the money that's stolen from us every year so much human suffering could be reduced. It all but leaves me speechless to ponder such a thing, yet there it is.
The other thing that strikes me is the fact there are so many good people willing to go that extra mile to innovate and offer up solutions that make so much sense. It's been 10 years since the events occurred that inspired this man, can anyone tell me how much support he received to implement this solution ?
Sounds good but this bottle is around $100 bucks for 1 and the Jerry can is around $300
I love the idea Its terrific
The best TED presentation
Hi! Thank you all for your comments, the price point we have makes it at alot less than 1p per litre and the process of making the bottle is an expensive one - we have alot of testing and constant development happening. Thank you all for your comments :-)
When did TED become shark tank?
Most of the projects presented on TED had full potential. Shark Tank shows many many MANY stupid projects.
Always was. Now they're just shameless about it
LMAO, you really aren't that smart if you don't realise why there is so much control over water.
If you can’t understand why he is emphasizing in the numbers.... then you gotta go back to college because you just missed a hole lecture.
When I ask my 11 year old son why is he inventing that.. do you know what he told me?
Because is “too expensive” to bring CLEAN WATER TO THE HOLE WORLD...my 11 year old.
There are aready water filters that kill virus and bacteria but way too expensive.
HE JUST FIXED THE PROBLEM.
Its great thank u who created this,Where we can buy it ?
gosh I LOVE THIS GUY

@@noragriffin6432 Oh my God, lady. Piss off!
What a wonderful talk! I thoroughly agree and am most impressed with your invention and physics. I recently found another Water talk on RUclips which I thought you would love as well. I'm not an inventor or physicist and so I am forwarding a few my notes for your perusal.
- Fresh water is becoming scarce all around the world. Let's use nano-technology through chemistry to build a de-salination plant with no heat involved and which never stops running. Water from the sea or ocean goes in one end (first stage) and out the other (second stage). The first stage has magnetic nano-robots programmed to find and grab the salt, making the salt magnetic! The second stage has electro-magnets which pull the salt from the nano-robots and dump the salt in one container and the clear water into a separate reservoir. The by-products are salt, which is in high demand from 3rd world countries, and clear water, which is in demand from everyone! I would love to see this accomplished! P.S. There was talk of steam being used from drilling anywhere on the Earth just a few kms to extract it without danger, but I'm not real clear on how that was described. This talk can be found on RUclips as Kryon They Are Coming and is discussed in the second half. Keep an open mind - it's a bit different than most talks!)
Wonderful
Brilliant
This reminds me of infomercials from the 90s. He should say, "just set it and forget it!"
Just give the people who need it , for free if you care so much Mr.Deep Pockets !
Why do you think they charge so much for them? The whole point is to charge westerns who don’t need them a premium for them, then use that to subsidise giving them to those in need for free
Such a great man
I love the ending
love this product, i own 2 of the water bottles and 1 of their jerry cans, my wife, family and i use them every day. keep up the good work.
Here is another idea: Teach people how to do basic water filtering with a cloth and inform them how long they got to boil the water over a fire to make it safe to drink and we'll save 8 billion $ to make this guy rich. Information weights nothing.
The Lifesaver bottle is much quicker and more convenient, no?
true !
Can people escaping a sunami even have the materials to build a fire even? They are running without camping gear, by the way.
Wow!
Good stuff.
Steam distillation is 100% and easy. boil the water in a Kettle or pot and catch the condensation in another container or through a flex tube and let it drip into a bottle. you don't need to spend allot of money. seems like all these gadgets cost around $400. there's a number of good examples on RUclips on how to distill water. Or by gallon of it at Walmart for $0.88.

Genius idea ! . .
Is this still being applied to places like Yemen?
It’s remarkable how many people are still alive in the world, if you think about it. Erm... was that your point?
Previous commenters you guys do realize that this man's presentation was basically aimed at planting the seeds of thought FOR full scale funding from either Uber - rich corporate investors OR the government...or one and the same as in the case of "1st world" nations?
Or if you prefer to be cynical you could call it a sales pitch.
Nonetheless you heard his little blurb about the cost effectiveness of investing in distributing these bottles and Jerry cans in the communities, versus the price of setting up a MASSIVE, water treatment/recycle infrastructure?? That's why he reiterates "our (their) current way of thinking."
...and who would control and profit from corporate owned, federally managed infrastructure water sanitation plants? So it's like this....
Give a man a fish he eats for a day.
Teach a man to fish he eats for life.
Remove the fish from the ocean first, poison the water, and offer your fish to the man at a price....
The rest is history.
Regardless of the problem of what would appear to be an overzealous retail price, the guy deserves praise. Besides the price is only unreasonable in terms of cost for 3rd world residents....which is exactly why he's pitching the idea!
Russell Jones Many if not most who watch these videos don't realize the cost of admission to a TED event.
waswestkan the devil's in the details, no?
Thank you for your logic, finally.
At least you seem to be TRYING to be fair. If you think his product "appear(s) to be an overzealous retail price" then purchase a different product or make something just as good yourself! But DO NOT BERATE someone for trying to HELP others. Now, if your contention is that government(s) will be in line to buy these (DOUBTFUL!), then it's the taxpayers that are ultimately "on the hook" for them. OBVIOUSLY, a "bulk price" would definitely be warranted and should be negotiated if at all possible. Even better, perhaps governments should JUST govern, and leave individuals to take care of themselves. Government is NOT a charitable organization! (Or, at least, it was never designed to be, and it should NOT be used in such a manner! But trying to get people who've existed in Western Civilization over the last 100 years to ultimately realize this has been - at the very least - "uphill"!) When "the market" and tax-payer supported "government" are mixed, you get an AWFUL mix of communism and capitalism; to be sure REAL capitalism hasn't been seen in the USA for over 100 years!!! What we have now is - at best - CRONY capitalism! We have corporations that make demands on politicians who are supposed to represent the PEOPLE, and - in turn - those very same PEOPLE have to go work for the corporations that make demands of the politicians - lining their pockets with campaign contributions, etc. The whole system needs an ENEMA! But do NOT put down a guy trying to help and get ahead for coming up with a solution that can actually legitimately HELP! Unless you have a better idea (proverbial "mousetrap") then be quiet and let others try to help!
The idea has merit. Cost will come down when the product is widespread. Kinda like a solar panel.
hi this is very good technic for re use the water can we clean the water with ladge amount of waer what can we do pls send me the details n how much cost

Sawyer water filter 30 bucks 1 million gallons.....
Nothing new, Water filters have been around for years.
Out of curiosity, how/when does one need to open up the bottle to cleanse the actual filter from earlier uses? The bacteria and such will gather up inside.
Excellent salesman.
I really hate such do-gooders, presumptuous, haughty and superior only making money off the misery of poor people. Instead of giving them 'this Bottle', why not teach them how to filter their water using their own material. It is a very simple process. You set up a filtration systems for drinking water. It is a 3 tier systems using local earthenware like a big pot. The first pot at the top should have 3 layers: 1st: husks, gravel and sand. The 2nd one should have pulverized charcoal and the 3rd shall have clean drinkable water. Chinese, Indians and Persians have been using this method for generations. This 3 layers systems can be extended to 5 or even 7 layers. In China, India and many African Countries have clean drinking water sold in clear plastic sachets. It has reduced water borne disease in these countries.
