00:15
Cholera was reported in Haiti
0
15260
2000
Kolera se pojavila na Haitiju
00:17
for the first time in over 50 years
1
17260
2000
po prvi put u više od 50 godina
00:19
last October.
2
19260
2000
prošlog listopada.
00:21
There was no way to predict
3
21260
2000
Nije se moglo predvidjeti
00:23
how far it would spread through water supplies
4
23260
3000
koliko će se proširiti vodom
00:26
and how bad the situation would get.
5
26260
3000
i koliko će se situacija pogoršati.
00:29
And not knowing where help was needed
6
29260
2000
Budući da se nije znalo gdje je pomoć potrebna,
00:31
always ensured that help was in short supply
7
31260
3000
nikad je nije bilo dovoljno
00:34
in the areas that needed it most.
8
34260
3000
na područjima koja su je najviše trebala.
00:37
We've gotten good at predicting and preparing for storms
9
37260
3000
Uspješno predviđamo i pripremamo se za oluje
00:40
before they take innocent lives
10
40260
2000
prije nego uzmu nevine živote
00:42
and cause irreversible damage,
11
42260
2000
i nanesu nepopravljivu štetu,
00:44
but we still can't do that with water,
12
44260
2000
ali to još uvijek ne možemo učiniti s vodom,
00:46
and here's why.
13
46260
2000
a evo zašto.
00:48
Right now, if you want to test water in the field,
14
48260
2000
U ovom trenutku, ako želite testirati vodu na terenu,
00:50
you need a trained technician,
15
50260
2000
trebate kvalificiranog tehničara,
00:52
expensive equipment like this,
16
52260
2000
skupu opremu poput ove
00:54
and you have to wait about a day
17
54260
2000
i morate čekati oko jedan dan
00:56
for chemical reactions to take place and provide results.
18
56260
3000
da kemijske reakcije naprave svoje i daju rezultate.
00:59
It's too slow
19
59260
2000
To je presporo
01:01
to get a picture of conditions on the ground
20
61260
2000
da bismo stekli sliku o uvjetima na terenu
01:03
before they change,
21
63260
2000
prije no što se promijene,
01:05
too expensive to implement
22
65260
2000
preskupo je za primjenu
01:07
in all the places that require testing.
23
67260
2000
na svim mjestima na kojima je testiranje potrebno.
01:09
And it ignores the fact that, in the meanwhile,
24
69260
2000
A to sve još ne uključuje činjenicu da
01:11
people still need to drink water.
25
71260
2000
u međuvremenu ljudi ipak trebaju piti vodu.
01:13
Most of the information that we collected on the cholera outbreak
26
73260
3000
Većinu informacija koje smo skupili o pojavi kolere
01:16
didn't come from testing water;
27
76260
2000
nismo dobili kroz testiranje vode.
01:18
it came from forms like this,
28
78260
2000
Dobili smo ih iz ovakvih obrazaca,
01:20
which documented all the people
29
80260
2000
u kojima su zapisani svi ljudi
01:22
we failed to help.
30
82260
2000
kojima nismo uspjeli pomoći.
01:24
Countless lives have been saved
31
84260
2000
Bezbroj života spasili su
01:26
by canaries in coalmines --
32
86260
2000
kanarinci u rudnicima --
01:28
a simple and invaluable way
33
88260
2000
jednostavan i neprocjenjiv način
01:30
for miners to know whether they're safe.
34
90260
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
92260
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
95260
3000
s nekima od najmarljivijih i najpametnijih ljudi koje poznajem.
01:38
We think there's a simpler solution to this problem --
37
98260
2000
Mislimo da postoji jednostavnije rješenje ovog problema --
01:40
one that can be used
38
100260
2000
i to takvo koje mogu koristiti
01:42
by people who face conditions like this everyday.
39
102260
2000
ljudi koji su svakodnevno suočeni s takvim uvjetima.
01:44
It's in its early stages,
40
104260
2000
Još je u razvojnoj fazi,
01:46
but this is what it looks like right now.
41
106260
3000
ali evo kako trenutno izgleda.
01:49
We call it the Water Canary.
42
109260
2000
Zovemo ga Vodenim kanarincem.
01:51
It's a fast, cheap device
43
111260
3000
To je brz, jeftin uređaj
01:54
that answers an important question:
44
114260
2000
koji daje odgovor na važno pitanje:
01:56
Is this water contaminated?
45
116260
2000
je li voda zagađena?
01:58
It doesn't require any special training.
46
118260
3000
Nije potrebno posebno osposobljavanje.
02:01
And instead of waiting for chemical reactions to take place,
47
121260
3000
Umjesto da čeka završetak kemijskih reakcija,
02:04
it uses light.
48
124260
2000
on koristi svjetlost.
02:06
That means there's no waiting
49
126260
2000
To znači da nema čekanja
02:08
for chemical reactions to take place,
50
128260
2000
da završe kemijske reakcije,
02:10
no need to use reagents that can run out
51
130260
2000
ne trebaju se koristiti reagensi koji se mogu potrošiti
02:12
and no need to be an expert
52
132260
2000
i ne morate biti stručnjak
02:14
to get actionable information.
53
134260
3000
da biste dobili relevantne informacije.
02:17
To test water, you simply insert a sample
54
137260
2000
Da biste testirali vodu, samo unesete uzorak
02:19
and, within seconds,
55
139260
2000
i za nekoliko sekundi
02:21
it either displays a red light, indicating contaminated water,
56
141260
3000
pojavi se ili crveno svjetlo, što znači zagađenost,
02:24
or a green light, indicating the sample is safe.
57
144260
2000
ili zeleno svjetlo, što znači da je voda čista.
02:26
This will make it possible
58
146260
2000
Tako će se svima omogućiti
02:28
for anyone to collect life-saving information
59
148260
3000
dobivanje informacija koje mogu spasiti život
02:31
and to monitor water quality conditions as they unfold.
60
151260
3000
i stalno praćenje kvalitete vode.
02:34
We're also, on top of that,
61
154260
3000
Osim toga,
02:37
integrating wireless networking
62
157260
3000
ugrađujemo i bežično povezivanje
02:40
into an affordable device
63
160260
2000
u jeftin uređaj
02:42
with GPS and GSM.
64
162260
2000
s GPS-om i GSM-om.
02:44
What that means is that each reading can be automatically transmitted to servers
65
164260
3000
To znači da se svako očitanje može automatski prebaciti na servere
02:47
to be mapped in real time.
66
167260
2000
i pratiti u stvarnom vremenu.
02:49
With enough users,
67
169260
2000
S dovoljno korisnika,
02:51
maps like this will make it possible
68
171260
2000
ovakve će mape omogućiti
02:53
to take preventive action,
69
173260
2000
poduzimanje preventivnih radnji,
02:55
containing hazards before they turn into emergencies
70
175260
3000
čime će se opasnosti zauzdati prije nego prerastu u hitne situacije
02:58
that take years to recover from.
71
178260
2000
od kojih će se ljudi godinama oporavljati.
03:00
And then, instead of taking days
72
180260
2000
A onda, umjesto da budu potrebni dani
03:02
to disseminate this information to the people who need it most,
73
182260
2000
da se te informacije proslijede ljudima koji ih najviše trebaju,
03:04
it can happen automatically.
74
184260
3000
to se može događati automatski.
03:07
We've seen how distributed networks,
75
187260
2000
Vidjeli smo kako distributivne mreže,
03:09
big data and information
76
189260
2000
veliki podaci i informacije
03:11
can transform society.
77
191260
2000
mogu promijeniti društvo.
03:13
I think it's time for us to apply them to water.
78
193260
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
196260
2000
Naš je cilj da u idućih godinu dana Vodenog kanarinca pripremimo za teren
03:18
and to open-source the hardware
80
198260
2000
i da ga učinimo dostupnim svima,
03:20
so that anyone can contribute to the development and the evaluation,
81
200260
3000
tako da će svi moći doprinijeti razvoju i evaluaciji
03:23
so we can tackle this problem together.
82
203260
2000
i da ćemo moći zajedno rješavati ovaj problem.
03:25
Thank you.
83
205260
2000
Hvala.
