Sonaar Luthra: Meet the Water Canary

[MichaelSmathers]

ATTENTION IDIOT* silver colloidal Ions from normal silver metal DESTROY virulent pathogens...

So before you rant about a complex system of intellectual bullshit with million dollar funds from Other Peoples Money. Consider this: (KISS)

Go play a liberal Politician or Eco- Freak with OPM......SOMEWHERE ELSE!

[mrdotbryce]

blunt promises he demonstrates nothing he doesnt even say what the device tests for !! is this an attempt at seducing business partners ? very disappointed with similar advertisements regularly being validated on ted

[JohnShandy]

@mrdotbryce Dear fucking moron, as he did say, the device tests for pathogens such as cholera. Signed, -Normal person

Homosexual activists understand the power of words.

Please visit my channel to watch a one-minute video clip in which popular atheist author Richard Dawkins admits that homosexual activists "hijacked the word 'gay'".

The word "homosexual" is more appropriate and accurate because it, unlike the word "gay", actually describes the behavior/attraction/relationsh­ip being discussed.

The word "gay" helps homosexual activists push their agenda.

[USMerchantMarines]

Someone please explain the dislikes to me.

[Gazonkie]

open-source hardware, wow.. incredible

[haigfeinn]

spread the water!!!

[dans1121]

i would have liked to hear this a year from now when they would actually explain the product

[machinevos]

lovely!

[superdiza]

sounds like magic. green light/red light.

[ennot]

yes, but what's the idea?

[daras07]

@ennot They are probably just measuring how much light is scattered or absorbed in the sample... like ordinary turbidity measurements..

[TheZietgiest]

water is life

[ElmoNotty]

hope we can get to it soon D:

[GetMeThere1]

I don't actually understand why this is so great?!?! A water source that tests fine might be bad in half an hour. Ultimately, what's needed is standard filtration, etc., that TREATS water in such situations--it's much less important, I think, to "know" if water is bad--it's more practical to ASSUME it's bad, and treat it.

Furthermore, regarding disease contamination, one can ALREADY have a small iodine or chlorine "kit," which obviates a need to "test" using a similar sized kit.

[ennot]

@GetMeThere1 filtering all water is not technically feasible in most places. Even technologically advanced nations guard their water supplies from pollution. And even if all water consumed by people were filtered, animals will still be affected and spread the disease.

Look at it this way - do you use a smoke detector or a breathing apparatus at home?

[GetMeThere1]

@ennot : The talk was about what to do in emergency situations, ala Haiti. In such situations, actual water treatment is needed. People got cholera there because the contaminated water was ALL THEY HAD--the ability to test it wouldn't have made a difference. The ability to filter/treat it would.

[Bfavrestarr415]

What a great way to start the morning. Awesome idea.

[asdfgoogle]

Awesome! Short and sweet!

Also, did you guys see the EARS on this man?? I'm glad I grew into my ears from when I was younger. lol.

[Shell4445]

well done, thank you, sharing

[tinosnit]

I want one.

[felixthehuman]

Fluorescence? Scattering? Turbidity? Spectroscopy?

[slLLyhumans]

Damn nice .

[ahsan2mahmood]

OK,its amazing...........BUT HOW DOES IT WORK???

[monkeyrecordsnz]

How can you dislike a video previewing an invention that could save thousands upon thousands of lives?

[MrHashmoney01]

Great talk. Simple and to the point. Sounds like a much needed device.

[azmanabdula]

ok...found a pond...YEHAAA

got my water canary...

power socket?

farrrrk

[WiiAreSIN]

@azmanabdula ...it uses battery...

[azmanabdula]

@WiiAreSIN batteries go flat : P

thats all im saying...

[MRL1985]

@azmanabdula It's ok, it's a device for scientists, scientists will know what to do if they need a charge... We may find out how they're going with the theories and probable solutions on why the battery won't remained charged in the next TED video!

[azmanabdula]

@MRL1985 but isnt this meant for commercial use? in places with no electricity and no water treatment plants?

seriously, what if it is flat?

or does it only use energy when a tablet is in there?

[azmanabdula]

@MRL1985 question mark abuse! sorry

[JustinRoth93]

cool video!



[peacheramerika]

exactly.. where n how much is this water testing thing?

[Robinsonero]

where can i buy one?

[ymarmash]

no patent yet hence the lack of explanation...

[lebasson]

@ymarmash how does patenting a product actually relate to opensourcing it?

[defaultuser88]

so by "uses light" does he mean it just shows a red/green light based on if the solution passes a certain absorbance threshold? cus that dere is sum pretty unscientific testing

[Telleryn]

It's obviously powered by magic

[AcruxSolus]

Why does he keep squinting his eyes? Does he need to shit?

[DaNZOmen]

@AcruxSolus The guy looks high as crap

[maddcatone]

@AcruxSolus Haha no man. Stand on a stage, in front of hundreds of people, with spotlights glaring into your near sighted eyes... interesting combo. Enough to make you look blasted high

[ironlionkalo]

for the water canary, did you use technology or was it a nontechnology?

[unluckylion]

I think it is a simple photometer, so you shine light trough the water and depending on the light you get out on the other side you know if the water is contaminated. however I'm suspicious if it can detect dangerous chemicals and small concentration of bacteria (I did work with those kind of instruments in a biology lab, and it's not as simple as putting the water in)... but if it work's it would be awesome.

[littlestworkshop]

@unluckylion It is a spectrometer, at least according to their website.

[ThePeoplesGuru]

This faggot talks like he just single handedly saved the word. Yet we don't even know if that's just a yellow concept box with an LED light ontop. What a pretentious fuck.

[jdroker]

It seems like something they aim to do instead of something they had done.

[hippodude100]

It uses light so you don't have to wait for a chemical reaction ?

I really don't see how.

Not digging this ted talk. Sounds all fancy but I don't see this happening

[1ucasvb]

The official site is also incredibly vague. This looks like one of those void investment baits.

[NobodysOffTheHook]

Amazing!

[DaBamBamMan]

It's amazing how people want to sit on a video on youtube and ask all these questions they should be e-mailing to the creators of this device if they are so "concerned" that it's fake. Do you people even know what TED is?

[hastalueguito]

@DaBamBamMan Personally, I know TED is about technology and spreading ideas and such, but never forget it could also be a marketing tool... I mean, someone must be paying for it... Nowadays we must always be aware, and never stop questioning things. We should have learnt from history by now to always question everything, dont you think?

[alpha4005]

People, please use your heads, he was given three minutes to speak, which most likely is not enough time to explain in depth on how this works. It was to get the word out and let others know that this project exists.

[Tnat1on]

0:15

[RDJim]

It works by employing magic water genies. Alternatively, you could simply submerge a real canary in the water. If it stops struggling after a few minutes, the water is contaminated. Who wants to drink water with a dead bird in it?

[Rarae192]

@RDJim Ehehehe! :D

I was gonna thumbs-down ya, but thumbsed-up ya because of that little twist at the end.

[HonkeyTonTon]

these guys are creating a device that will save millions of lives and not profiteering off it. inspiring. this should be what ted is about, not hippies with guitars

[Shalek]

watercanary(dot)com

[nittle90]

I bet none of the designers are red-green colorblind...

[MRL1985]

@nittle90 Doh!

[TheExtractor1]

Artige.no!

[andrewc2768]

I invented a device, and when you pointit at a TEDtalks screenshot, it tells you within seconds,if it is stupid or not. No watching a whole episode, no dangerous boredom or awkward fails, there is a red and green light and the red one.........

[Copperfoilhat]

If it uses light for analysis then he is talking about spectrophotometry.

[andrewc2768]

he should just invent a tricorder from Star Trek.

[TheIslammiracle]

@andrewc2768

I believe one has been invented and the creator(s) won a financial prize for it. Atleast thats what I heard.

[87sumedha]

Nothing much about its functionality is mentioned on their website either. The only bit of info mentioned is that "it uses patented spectral technology to reduce the time of testing". Strange

[frozencold199]

This looks like hes trying to sell something instead of helping people, tell us how it works, jesus christ this talk was really dumb

[Studi037]

Good elevator pitch if he's looking for venture capital...

Hope this isn't the new cold-fusion.

[captainhampton]

@Studi037 Skepticism is understandable, but comparing this to cold fusion I think is a bit of a stretch. The device, or one similar to it can't be that difficult to mass produce and rely on for yielding accurate data on water.

[Studi037]

It is. However, both claim to work hocus pocus with water and save humankind in the process...

I will be very, very excited if this is an actual piece of technology.

@captainhampton

[sparrow111260]

Wonderful news!

[doford]

Surely my eyes do the same job but for free.

[Josephhanul]

this is too short

[strek0655]

Vibrio Cholera can be seen with dark-field microscope, which is not very time consuming and as many people also state, there is a very simple solution to the problem: BOILING THE WATER!

Devices like this are likely to bee too low in sensitivity and/or specificity to be trusted with a potentially dangerous infection such as Cholera. Again, boiling and use of disinfectants are key in situations such as in Haiti.

[metahelix]

This is brilliant, if they combine this technology with life saver water purifiers which are not overly expensive, we can save so many lives. TED= A BETTER TOMORROW

[hazeee123]

This is what can be found on their website: The Technology

The Water Canary’s exclusive use of patented spectral technology reduces to seconds the testing time for disease-­causing pathogens, lowering the cost per test to a fraction of current solutions.

watercanary[dot]com

[VortexContinuum]

Looks like an ad to build hype for their product.

[divineagent]

Sounds like it's shining light through the water to see the bacteria and shit.

[bamboo4tameshigiri]

News flash: Boil your fucking water when you're in the field.

[soulsanctuarymusic1]

@bamboo4tameshigiri I'm not sure if you're living in such rough conditions boiling water is always a viable solution.

[DarkAura971]

It's in its early stages so right now, it's like an idea that's sure to happen, and a good one. Basically, he just said you can test water with almost no money and no knowledge. All you have to do is distinguish two different colors and know how to put water inside it. I think it's a great idea. I know he didn't go into the specifics but maybe that's because he doesn't know them yet. He knows we going to make a life saver and how it works. That's good enough

TED = AWESOME

[HensPie]

inspired by twitter 

[emadtvshow]

Can i reach transcript of these videos???

[PBDPBD]

@emadtvshow go to the TED website. The transcripts are there.

[PBDPBD]

"it uses light"... uh... ok? It sounds like it's just a tiny, cheap spectrophotometer. If so, it would be pretty useless. You can't tell with much accuracy whether something is safe to drink or not purely by the color or attenuation properties of water.

[dkwline]

Excellent! This fellow sounded like a student of the late great Louis Buscaglia

[gamegloss]

@dkwline You mean Leo Buscaglia? 

[Morkvonork]

I dont know. I think early and massive preventive use of water purification agents like chlorine would be more helpful than this because this spectrometer(I think its one) tells you only if it is already too late and they are also not very specific too so other stuff could easily cause a posivite reading.

[cowpacino]

he didn't explain the device at all

[dude12nothin]

@cowpacino Cause that's not the main point but he did say it uses light to test the water.

[apocaRUFF]

@cowpacino He had 3 minutes.

[soulsanctuarymusic1]

@cowpacino They only gave him 3 minutes, which seems unfair given that it seems like a pretty awesome device. I'm sure if he'd had longer he would of expended on what he said.

[Aresftfun]

@cowpacino They're all timed. He just didn't have enough time. *shrug*

[SiliconBong]

If it kills you, it's not safe to drink, cowpacino

[quaxk]

@cowpacino it's nothing more than a simplified, pocktable spectrometer, I don't think it can detect pathogens, only specific contaminants

[manpaisa92]

@cowpacino he had less than 5minutes...

[Ghost00117]

BUT HOW DOES IT WORK!? I mean if it's open source, we should know if we want to help shouldn't we? What are the different contaminants it tests for? I guess because it's in early stages they don't have the answer to these and other important questions?

[sacrux]

@Ghost00117 I guess just cholera. Wonder what the ppm has to be.

TED should include follow/blog links for the speakers.

[aluphoss]

@Ghost00117 It could just be that they didn't give him a long enough time slot?

[alpha4005]

@Ghost00117 If the answer is that important to you then do what others do. Go to TED.com, look up this talk, and use the contact the speaker utility. You could also look up their website. Those that want to make a difference will do the work required. Do not think that everything will be handed to you.

[Ghost00117]

@alpha4005 I'm not asking for things to be handed to me. It just seemed improper to introduce such a device, call it open source, and NOT describe how it works. He really should have been given enough time to talk about how it works, IMO. I'll try finding out more using your suggestion. Thanks for the comment.

[Mrmoc7]

@Ghost00117

He only had 3:38!

[Mrmoc7]

@Mrmoc7

Scratch that, he only had 3:23!

[maxjosephwheeler]

HELL YEAH!!! So much better than the last vid!!!

[TheGerogero]

I'm not one to doubt the science behind new technology but an explanation on mechanism was almost entirely absent and that annoyed me.

RIP coal mine canaries.

[CognitiveApprentice]

That fact that this project is intended to be open-source... = WIN!!

[gearhead135]

I feel bad for the coal mine canaries ;(

[myndwork]

more time, and more info please, whats the science behind the device, i do not want to follow it blindly.

[14ByTheSword]

It's soo exhausting. How much time and resources will continue to be wasted on a people who are simply too inept to help themselves with even the most provisions and assistance.

[rakketakke]

I like his glasses

[twistedbass15]

GENIUS

[JakXenon]

im not even sure what the device does, so it uses light but to do what? this guy needed more time.

[Kotesu]

@JakXenon The sample loader looks like something used in UV-Vis spectroscopy. With CMOS cameras being manufactured in bulk for cell phones and webcams, and diffraction gratings being easy to make, I should be pretty cheap to get a good spectrograph. It would be a bitch to analyze the readings though, but that's the approach I would take.

[skillbill83]

I want a Canary.
