00:15
Cholera was reported in Haiti
0
15260
2000
A Haití, el còlera va aparèixer
00:17
for the first time in over 50 years
1
17260
2000
per primer cop després de 50 anys
00:19
last October.
2
19260
2000
l'octubre passat.
00:21
There was no way to predict
3
21260
2000
No es podia saber
00:23
how far it would spread through water supplies
4
23260
3000
fins on s'extendria a través dels suministres d'aigua
00:26
and how bad the situation would get.
5
26260
3000
i el seu grau de gravetat.
00:29
And not knowing where help was needed
6
29260
2000
I no saber on es necessitava ajuda
00:31
always ensured that help was in short supply
7
31260
3000
feia que aquesta no arribés mai
00:34
in the areas that needed it most.
8
34260
3000
allà on la necessitaven més.
00:37
We've gotten good at predicting and preparing for storms
9
37260
3000
Som bons preveient tempestes
00:40
before they take innocent lives
10
40260
2000
abans que causin morts
00:42
and cause irreversible damage,
11
42260
2000
i danys irreparables,
00:44
but we still can't do that with water,
12
44260
2000
però amb l'aigua encara no.
00:46
and here's why.
13
46260
2000
Us explicaré el perquè.
00:48
Right now, if you want to test water in the field,
14
48260
2000
Si voleu examinar l'aigua in situ,
00:50
you need a trained technician,
15
50260
2000
necessiteu un especialista,
00:52
expensive equipment like this,
16
52260
2000
un equip car,
00:54
and you have to wait about a day
17
54260
2000
i heu d'esperar un dia
00:56
for chemical reactions to take place and provide results.
18
56260
3000
per a l'obtenció dels resultats.
00:59
It's too slow
19
59260
2000
És massa lent
01:01
to get a picture of conditions on the ground
20
61260
2000
per a obtenir un esquema de les condicions
01:03
before they change,
21
63260
2000
abans que canvïin,
01:05
too expensive to implement
22
65260
2000
massa car per a fer-ho
01:07
in all the places that require testing.
23
67260
2000
en tots els llocs afectats.
01:09
And it ignores the fact that, in the meanwhile,
24
69260
2000
I mentrestant,
01:11
people still need to drink water.
25
71260
2000
la gent necessita beure aigua.
01:13
Most of the information that we collected on the cholera outbreak
26
73260
3000
La majoria de la informació que hem obtingut del cólera
01:16
didn't come from testing water;
27
76260
2000
no ve de l'aigua examinada,
01:18
it came from forms like this,
28
78260
2000
sinó que ve dels informes
01:20
which documented all the people
29
80260
2000
de totes aquelles persones
01:22
we failed to help.
30
82260
2000
que no hem pogut ajudar.
01:24
Countless lives have been saved
31
84260
2000
S'han salvat moltes vides
01:26
by canaries in coalmines --
32
86260
2000
amb canaris dins de les mines:
01:28
a simple and invaluable way
33
88260
2000
una manera simple i inestimable
01:30
for miners to know whether they're safe.
34
90260
2000
per als miners de saber si estaven en perill.
01:32
I've been inspired by that simplicity as I've been working on this problem
35
92260
3000
M'he inspirat d'això mentres treballava en aquest problema
01:35
with some of the most hardworking and brilliant people I've ever known.
36
95260
3000
amb la gent més treballadora i brillant que he conegut mai.
01:38
We think there's a simpler solution to this problem --
37
98260
2000
Pensem que hi ha una solució més simple,
01:40
one that can be used
38
100260
2000
una que pot utilitzar
01:42
by people who face conditions like this everyday.
39
102260
2000
la gent que afronta aquestes condicions.
01:44
It's in its early stages,
40
104260
2000
Només és un prototip,
01:46
but this is what it looks like right now.
41
106260
3000
i és bàsicament això.
01:49
We call it the Water Canary.
42
109260
2000
És el "Water Canary",
01:51
It's a fast, cheap device
43
111260
3000
un aparell ràpid i barat,
01:54
that answers an important question:
44
114260
2000
que respon a una pregunta important:
01:56
Is this water contaminated?
45
116260
2000
Aquesta aigua està contaminada?
01:58
It doesn't require any special training.
46
118260
3000
No cal entrenament,
02:01
And instead of waiting for chemical reactions to take place,
47
121260
3000
i en comptes d'esperar reaccions químiques,
02:04
it uses light.
48
124260
2000
utilitza una llum.
02:06
That means there's no waiting
49
126260
2000
Vol dir que no cal esperar
02:08
for chemical reactions to take place,
50
128260
2000
les reaccions químiques,
02:10
no need to use reagents that can run out
51
130260
2000
no calen reactius, que s'esgoten,
02:12
and no need to be an expert
52
132260
2000
i no cal ser un expert
02:14
to get actionable information.
53
134260
3000
per entendre els seus resultats.
02:17
To test water, you simply insert a sample
54
137260
2000
Per examinar l'aigua, n'hi posem una mica
02:19
and, within seconds,
55
139260
2000
i en pocs segons,
02:21
it either displays a red light, indicating contaminated water,
56
141260
3000
o bé surt una llum vermella, que indica que està contaminada,
02:24
or a green light, indicating the sample is safe.
57
144260
2000
o bé una llum verda si la mostra és segura.
02:26
This will make it possible
58
146260
2000
Això permet que
02:28
for anyone to collect life-saving information
59
148260
3000
tothom tingui accés a informació vital
02:31
and to monitor water quality conditions as they unfold.
60
151260
3000
i pugui controlar la qualitat de l'aigua en tot moment.
02:34
We're also, on top of that,
61
154260
3000
A més a més,
02:37
integrating wireless networking
62
157260
3000
integrarem connexió inalàmbrica
02:40
into an affordable device
63
160260
2000
en un dispositiu a preu assequible
02:42
with GPS and GSM.
64
162260
2000
amb GPS i GSM.
02:44
What that means is that each reading can be automatically transmitted to servers
65
164260
3000
Així, tots els tests seran transmesos als servidors
02:47
to be mapped in real time.
66
167260
2000
per fer un mapa en temps real.
02:49
With enough users,
67
169260
2000
Amb suficients usuaris,
02:51
maps like this will make it possible
68
171260
2000
mapes així fan possible
02:53
to take preventive action,
69
173260
2000
l'acciò preventiva
02:55
containing hazards before they turn into emergencies
70
175260
3000
contenint els riscos abans que es tornin emergències
02:58
that take years to recover from.
71
178260
2000
que triguen anys a resoldre's.
03:00
And then, instead of taking days
72
180260
2000
En comptes de trigar dies
03:02
to disseminate this information to the people who need it most,
73
182260
2000
per informar les persones que més ho necessiten,
03:04
it can happen automatically.
74
184260
3000
així es fa automàticament.
03:07
We've seen how distributed networks,
75
187260
2000
Hem vist com les xarxes
03:09
big data and information
76
189260
2000
i la Informació poden
03:11
can transform society.
77
191260
2000
transformar la societat.
03:13
I think it's time for us to apply them to water.
78
193260
3000
És el moment d'aplicar-les a l'aigua.
03:16
Our goal over the next year is to get Water Canary ready for the field
79
196260
2000
L'any que ve, volem un Water Canary preparat pel terreny
03:18
and to open-source the hardware
80
198260
2000
i deixar-lo amb codi obert
03:20
so that anyone can contribute to the development and the evaluation,
81
200260
3000
perquè tothom pugui contribuir al seu desenvolupament
03:23
so we can tackle this problem together.
82
203260
2000
i afrontar junts aquest problema.
03:25
Thank you.
83
205260
2000
Gràcies.
03:27
(Applause)
