Nakon krize, kako možemo znati je li voda dobra za piće? Testovi koji se trenutno koriste spori su i složeni, a kašnjenje rezultata može biti kobno, kao u slučaju širenja kolere nakon potresa na Haitiju 2010. godine. Sonaar Luthra, TED Kolega, predstavlja svoj dizajn jednostavne sprave koja brzo ispituje je li voda sigurna -- Vodenog kanarinca.

Cholera was reported in Haiti
0
0
2000
Kolera se pojavila na Haitiju
00:17
for the first time in over 50 years
1
2000
2000
po prvi put u više od 50 godina
00:19
last October.
2
4000
2000
prošlog listopada.
00:21
There was no way to predict
3
6000
2000
Nije se moglo predvidjeti
00:23
how far it would spread through water supplies
4
8000
3000
koliko će se proširiti vodom
00:26
and how bad the situation would get.
5
11000
3000
i koliko će se situacija pogoršati.
00:29
And not knowing where help was needed
6
14000
2000
Budući da se nije znalo gdje je pomoć potrebna,
00:31
always ensured that help was in short supply
7
16000
3000
nikad je nije bilo dovoljno
00:34
in the areas that needed it most.
8
19000
3000
na područjima koja su je najviše trebala.
00:37
We've gotten good at predicting and preparing for storms
9
22000
3000
Uspješno predviđamo i pripremamo se za oluje
00:40
before they take innocent lives
10
25000
2000
prije nego uzmu nevine živote
00:42
and cause irreversible damage,
11
27000
2000
i nanesu nepopravljivu štetu,
00:44
but we still can't do that with water,
12
29000
2000
ali to još uvijek ne možemo učiniti s vodom,
00:46
and here's why.
13
31000
2000
a evo zašto.
00:48
Right now, if you want to test water in the field,
14
33000
2000
U ovom trenutku, ako želite testirati vodu na terenu,
00:50
you need a trained technician,
15
35000
2000
trebate kvalificiranog tehničara,
00:52
expensive equipment like this,
16
37000
2000
skupu opremu poput ove
00:54
and you have to wait about a day
17
39000
2000
i morate čekati oko jedan dan
00:56
for chemical reactions to take place and provide results.
18
41000
3000
da kemijske reakcije naprave svoje i daju rezultate.
00:59
It's too slow
19
44000
2000
To je presporo
01:01
to get a picture of conditions on the ground
20
46000
2000
da bismo stekli sliku o uvjetima na terenu
01:03
before they change,
21
48000
2000
prije no što se promijene,
01:05
too expensive to implement
22
50000
2000
preskupo je za primjenu
01:07
in all the places that require testing.
23
52000
2000
na svim mjestima na kojima je testiranje potrebno.
01:09
And it ignores the fact that, in the meanwhile,
24
54000
2000
A to sve još ne uključuje činjenicu da
01:11
people still need to drink water.
25
56000
2000
u međuvremenu ljudi ipak trebaju piti vodu.
01:13
Most of the information that we collected on the cholera outbreak
26
58000
3000
Većinu informacija koje smo skupili o pojavi kolere
01:16
didn't come from testing water;
27
61000
2000
nismo dobili kroz testiranje vode.
01:18
it came from forms like this,
28
63000
2000
Dobili smo ih iz ovakvih obrazaca,
01:20
which documented all the people
29
65000
2000
u kojima su zapisani svi ljudi
01:22
we failed to help.
30
67000
2000
kojima nismo uspjeli pomoći.
01:24
Countless lives have been saved
31
69000
2000
Bezbroj života spasili su
01:26
by canaries in coalmines --
32
71000
2000
kanarinci u rudnicima --
01:28
a simple and invaluable way
33
73000
2000
jednostavan i neprocjenjiv način
01:30
for miners to know whether they're safe.
34
75000
2000
kako su rudari znali jesu li sigurni.
01:32
I've been inspired by that simplicity as I've been working on this problem
35
77000
3000
Ta jednostavnost inspirirala me dok sam radio na ovom problemu
01:35
with some of the most hardworking and brilliant people I've ever known.
36
80000
3000
s nekima od najmarljivijih i najpametnijih ljudi koje poznajem.
01:38
We think there's a simpler solution to this problem --
37
83000
2000
Mislimo da postoji jednostavnije rješenje ovog problema --
01:40
one that can be used
38
85000
2000
i to takvo koje mogu koristiti
01:42
by people who face conditions like this everyday.
39
87000
2000
ljudi koji su svakodnevno suočeni s takvim uvjetima.
01:44
It's in its early stages,
40
89000
2000
Još je u razvojnoj fazi,
01:46
but this is what it looks like right now.
41
91000
3000
ali evo kako trenutno izgleda.
01:49
We call it the Water Canary.
42
94000
2000
Zovemo ga Vodenim kanarincem.
01:51
It's a fast, cheap device
43
96000
3000
To je brz, jeftin uređaj
01:54
that answers an important question:
44
99000
2000
koji daje odgovor na važno pitanje:
01:56
Is this water contaminated?
45
101000
2000
je li voda zagađena?
01:58
It doesn't require any special training.
46
103000
3000
Nije potrebno posebno osposobljavanje.
02:01
And instead of waiting for chemical reactions to take place,
47
106000
3000
Umjesto da čeka završetak kemijskih reakcija,
02:04
it uses light.
48
109000
2000
on koristi svjetlost.
02:06
That means there's no waiting
49
111000
2000
To znači da nema čekanja
02:08
for chemical reactions to take place,
50
113000
2000
da završe kemijske reakcije,
02:10
no need to use reagents that can run out
51
115000
2000
ne trebaju se koristiti reagensi koji se mogu potrošiti
02:12
and no need to be an expert
52
117000
2000
i ne morate biti stručnjak
02:14
to get actionable information.
53
119000
3000
da biste dobili relevantne informacije.
02:17
To test water, you simply insert a sample
54
122000
2000
Da biste testirali vodu, samo unesete uzorak
02:19
and, within seconds,
55
124000
2000
i za nekoliko sekundi
02:21
it either displays a red light, indicating contaminated water,
56
126000
3000
pojavi se ili crveno svjetlo, što znači zagađenost,
02:24
or a green light, indicating the sample is safe.
57
129000
2000
ili zeleno svjetlo, što znači da je voda čista.
02:26
This will make it possible
58
131000
2000
Tako će se svima omogućiti
02:28
for anyone to collect life-saving information
59
133000
3000
dobivanje informacija koje mogu spasiti život
02:31
and to monitor water quality conditions as they unfold.
60
136000
3000
i stalno praćenje kvalitete vode.
02:34
We're also, on top of that,
61
139000
3000
Osim toga,
02:37
integrating wireless networking
62
142000
3000
ugrađujemo i bežično povezivanje
02:40
into an affordable device
63
145000
2000
u jeftin uređaj
02:42
with GPS and GSM.
64
147000
2000
s GPS-om i GSM-om.
02:44
What that means is that each reading can be automatically transmitted to servers
65
149000
3000
To znači da se svako očitanje može automatski prebaciti na servere
02:47
to be mapped in real time.
66
152000
2000
i pratiti u stvarnom vremenu.
02:49
With enough users,
67
154000
2000
S dovoljno korisnika,
02:51
maps like this will make it possible
68
156000
2000
ovakve će mape omogućiti
02:53
to take preventive action,
69
158000
2000
poduzimanje preventivnih radnji,
02:55
containing hazards before they turn into emergencies
70
160000
3000
čime će se opasnosti zauzdati prije nego prerastu u hitne situacije
02:58
that take years to recover from.
71
163000
2000
od kojih će se ljudi godinama oporavljati.
03:00
And then, instead of taking days
72
165000
2000
A onda, umjesto da budu potrebni dani
03:02
to disseminate this information to the people who need it most,
73
167000
2000
da se te informacije proslijede ljudima koji ih najviše trebaju,
03:04
it can happen automatically.
74
169000
3000
to se može događati automatski.
03:07
We've seen how distributed networks,
75
172000
2000
Vidjeli smo kako distributivne mreže,
03:09
big data and information
76
174000
2000
veliki podaci i informacije
03:11
can transform society.
77
176000
2000
mogu promijeniti društvo.
03:13
I think it's time for us to apply them to water.
78
178000
3000
Mislim da je vrijeme da to primijenimo na vodu.
03:16
Our goal over the next year is to get Water Canary ready for the field
79
181000
2000
Naš je cilj da u idućih godinu dana Vodenog kanarinca pripremimo za teren
03:18
and to open-source the hardware
80
183000
2000
i da ga učinimo dostupnim svima,
03:20
so that anyone can contribute to the development and the evaluation,
81
185000
3000
tako da će svi moći doprinijeti razvoju i evaluaciji
03:23
so we can tackle this problem together.
82
188000
2000
i da ćemo moći zajedno rješavati ovaj problem.
03:25
Thank you.
83
190000
2000
Hvala.
03:27

ABOUT THE SPEAKER
Sonaar Luthra -Sonaar Luthra is the creator of Water Canary, a water-testing device that collects real-time water-quality data from the field.
Why you should listen
Sonaar Luthra was a writer and educator when he enrolled in NYU's famed Interactive Telecommunications Program (ITP) -- a breeding ground for cross-disciplinary thinking. He tells the TED Blog what happened next:
"I wanted to come up with some way of becoming what I was calling an 'urban planner for the global village.' And ... I fell in love with circuitry and with making tangible objects that had real functionality. Next thing I knew, I found myself in a class called Design for UNICEF, taught by Clay Shirky in association with UNICEF’s Innovations Lab.
"I wanted to see what was possible with water, and I was lucky to have an incredible team and the support of faculty that were willing to take on such a huge challenge. We started off as novices but we all became water experts in the process."
