Koji je to ključni faktor u korištenju alternativne energije, poput energije sunca ili vjetra? Pohrana - - kako bi nam struja odmah bila dostupna, čak i kad nema sunca ili vjetra. U ovom pristupačnom, inspirirajućem predavanju, Donald Sadoway govori o budućnosti baterija velikih razmjera koje pohranjuju obnovljivu energiju. Kao što kaže: "O problemu moramo razmišljati na drukčiji način. Moramo razmišljati na veliko. Moramo razmišljati jeftino."

The electricity powering the lights in this theater

3000
Električna struja koja osvjetljava ovu dvoranu
00:18
was generated just moments ago.
1
3000
3000
proizvedena je prije par trenutaka.
00:21
Because the way things stand today,
2
6000
3000
Zbog današnje situacije,
00:24
electricity demand must be in constant balance
3
9000
3000
potražnja za električnom energijom mora biti u stalnoj ravnoteži
00:27
with electricity supply.
4
12000
3000
s dostupnom električnom energijom.
00:30
If in the time that it took me to walk out here on this stage,
5
15000
3000
Da je za vrijeme dok sam se penjao na ovu pozornicu
00:33
some tens of megawatts of wind power
6
18000
3000
nekih desetaka megavata struje proizvedene u vjetroelektranama
00:36
stopped pouring into the grid,
7
21000
3000
prestalo doticati u mrežu,
00:39
the difference would have to be made up
8
24000
2000
razliku bi odmah nadoknadili
00:41
from other generators immediately.
9
26000
4000
drugi generatori.
00:45
But coal plants, nuclear plants
10
30000
3000
Termoelektrane, nuklearne elektrane
00:48
can't respond fast enough.
11
33000
2000
ne mogu reagirati dovoljno brzo.
00:50
A giant battery could.
12
35000
2000
Ali divovska baterija može.
00:52
With a giant battery,
13
37000
2000
Pomoću divovske baterije
00:54
we'd be able to address the problem of intermittency
14
39000
3000
mogli bismo riješiti problem intermitentnosti
00:57
that prevents wind and solar
15
42000
2000
koji onemogućava da vjetar i sunce
00:59
from contributing to the grid
16
44000
2000
doprinose mreži
01:01
in the same way that coal, gas and nuclear do today.
17
46000
4000
na isti način na koji danas doprinose ugljen, plin i nuklearke.
01:05
You see, the battery
18
50000
2000
Vidite, baterija je
01:07
is the key enabling device here.
19
52000
3000
ključni faktor ovdje.
01:10
With it, we could draw electricity from the sun
20
55000
3000
Pomoću nje, možemo iskoristiti el. energiju sunca
01:13
even when the sun doesn't shine.
21
58000
2000
čak i kad sunce ne sija.
01:15
And that changes everything.
22
60000
3000
A to mijenja sve.
01:18
Because then renewables
23
63000
2000
Jer tada obnovljivi izvori energije,
01:20
such as wind and solar
24
65000
2000
poput vjetra i sunca
01:22
come out from the wings,
25
67000
2000
prestaju biti periferni
01:24
here to center stage.
26
69000
2000
i postaju jako bitni.
01:26
Today I want to tell you about such a device.
27
71000
3000
Danas vam želim pričati o takvom uređaju.
01:29
It's called the liquid metal battery.
28
74000
2000
Zove se tekuća baterija.
01:31
It's a new form of energy storage
29
76000
2000
To je novi način pohranjivanja energije
01:33
that I invented at MIT
30
78000
3000
razvijen na MIT-u
01:36
along with a team of my students
31
81000
2000
od strane tima sačinjenog od mojih studenata
01:38
and post-docs.
32
83000
2000
i postdoktoranata.
01:40
Now the theme of this year's TED Conference is Full Spectrum.
33
85000
3000
Tema ovogodišnje TED-ove konferencije je puni spektar.
01:43
The OED defines spectrum
34
88000
3000
OED definira spektar
01:46
as "The entire range of wavelengths
35
91000
3000
kao: "Cijeli raspon valnih duljina
01:49
of electromagnetic radiation,
36
94000
2000
elektromagnetske radijacije,
01:51
from the longest radio waves to the shortest gamma rays
37
96000
3000
od najdužih radio valova do najkraćih gama zraka,
01:54
of which the range of visible light
38
99000
3000
gdje je raspon vidljivog svijetla
01:57
is only a small part."
39
102000
2000
samo mali dio."
01:59
So I'm not here today only to tell you
40
104000
2000
Zato vam danas neću govoriti samo o tome
02:01
how my team at MIT has drawn out of nature
41
106000
3000
kako je moj tim na MIT-u od prirode izvukao
02:04
a solution to one of the world's great problems.
42
109000
3000
rješenje za jedan od najvećih svjetskih problema.
02:07
I want to go full spectrum and tell you how,
43
112000
3000
Želim prijeći cijeli proces i reći vam kako smo,
02:10
in the process of developing
44
115000
2000
u postupku razvoja
02:12
this new technology,
45
117000
2000
ove nove tehnologije,
02:14
we've uncovered some surprising heterodoxies
46
119000
3000
otkrili nekoliko zanimljivih heterodoksija,
02:17
that can serve as lessons for innovation,
47
122000
3000
koje mogu dobro doći u procesu invacija,
02:20
ideas worth spreading.
48
125000
3000
ideja koje vrijedi podijeliti.
02:23
And you know,
49
128000
2000
I znate,
02:25
if we're going to get this country out of its current energy situation,
50
130000
4000
ako želimo ovu zemlju izvuči iz trenutnog energetskog problema,
02:29
we can't just conserve our way out;
51
134000
3000
ne možemo zamrnznuti izlaz;
02:32
we can't just drill our way out;
52
137000
3000
ne možemo ga pronaći ni bušenjem;
02:35
we can't bomb our way out.
53
140000
2000
ne možemo ga ni bobmardirati.
02:37
We're going to do it the old-fashioned American way,
54
142000
2000
To čemo uraditi na dobri, stari američki način,
02:39
we're going to invent our way out,
55
144000
2000
sami ćemo izmisliti riješenje,
02:41
working together.
56
146000
2000
zajedničkim radom.
02:43
(Applause)
57
148000
3000
(Pljesak)
02:46
Now let's get started.
58
151000
2000
Počnimo.
02:48
The battery was invented about 200 years ago
59
153000
3000
Bateriju je izumio prije gotovo 200 godina
02:51
by a professor, Alessandro Volta,
60
156000
2000
profesor Alessandro Volta,
02:53
at the University of Padua in Italy.
61
158000
3000
na Sveučilištu Padova, u Italiji.
02:56
His invention gave birth to a new field of science,
62
161000
2000
Njegov izum doveo je do razvoja nove znanstvene grane,
02:58
electrochemistry,
63
163000
2000
elektrokemije,
03:00
and new technologies
64
165000
2000
i novih tehnologija,
03:02
such as electroplating.
65
167000
2000
poput galvaniziranja.
03:04
Perhaps overlooked,
66
169000
2000
Možda pomalo zanemaren,
03:06
Volta's invention of the battery
67
171000
2000
Voltin izum baterije
03:08
for the first time also
68
173000
2000
po prvi pute je uz to
03:10
demonstrated the utility of a professor.
69
175000
2000
ukazao na korisnost profesora.
03:12
(Laughter)
70
177000
2000
(Smijeh)
03:14
Until Volta, nobody could imagine
71
179000
2000
Do Volte, nitko nije mogao pojmiti
03:16
a professor could be of any use.
72
181000
3000
kako profesor može biti od koristi.
03:19
Here's the first battery --
73
184000
3000
Evo prve baterije...
03:22
a stack of coins, zinc and silver,
74
187000
3000
hrpa novčića, cink i srebro,
03:25
separated by cardboard soaked in brine.
75
190000
2000
odvojeni kartonom natobljenim u slanoj vodi.
03:27
This is the starting point
76
192000
2000
Ovo je početna točka
03:29
for designing a battery --
77
194000
2000
u stvaranju baterije...
03:31
two electrodes,
78
196000
2000
dvije elektrode,
03:33
in this case metals of different composition,
79
198000
2000
u ovom slučaju metali različitog sastava,
03:35
and an electrolyte,
80
200000
2000
i elektrolit,
03:37
in this case salt dissolved in water.
81
202000
2000
u ovom slučaju sol otopljena u vodi.
03:39
The science is that simple.
82
204000
2000
Znanost je tako jednostavna.
03:41
Admittedly, I've left out a few details.
83
206000
4000
Priznajem, izostavio sam par detalja.
03:45
Now I've taught you
84
210000
2000
Sad sam vas podučio
03:47
that battery science is straightforward
85
212000
2000
kako je znanost o bateriji jednostavna,
03:49
and the need for grid-level storage
86
214000
2000
a potreba za pohranom na razini mreže
03:51
is compelling,
87
216000
2000
nužnost,
03:53
but the fact is
88
218000
2000
ali činjenica je
03:55
that today there is simply no battery technology
89
220000
3000
kako danas jednostavo ne postoji tehnologija izrade baterija
03:58
capable of meeting
90
223000
2000
koja može zadovoljiti
04:00
the demanding performance requirements of the grid --
91
225000
4000
zahtjevne potreba mreže...
04:04
namely uncommonly high power,
92
229000
2000
uglavnom neuobičajeno jake struje,
04:06
long service lifetime
93
231000
2000
dugog vijeka trajanja
04:08
and super-low cost.
94
233000
2000
i super niskih troškova.
04:10
We need to think about the problem differently.
95
235000
3000
Problemu moramo pristupiti drukčije.
04:13
We need to think big,
96
238000
2000
Moramo razmišljati na veliko,
04:15
we need to think cheap.
97
240000
2000
moramo razmišljati jeftino.
04:17
So let's abandon the paradigm
98
242000
2000
Napustimo paradigmu
04:19
of let's search for the coolest chemistry
99
244000
3000
o pronalasku super kemijskog spoja
04:22
and then hopefully we'll chase down the cost curve
100
247000
2000
i tako ćemo, nadam se, izazvati pad krivulje troškova
04:24
by just making lots and lots of product.
101
249000
3000
proizvodnjom velike količine proizvoda.
04:27
Instead, let's invent
102
252000
2000
Umjesto toga, hajdemo izumiti
04:29
to the price point of the electricity market.
103
254000
3000
nešto po cijeni pogodnoj za tržište el. energije.
04:32
So that means
104
257000
2000
To znači
04:34
that certain parts of the periodic table
105
259000
2000
kako su određeni dijelovi periodičnog sustava
04:36
are axiomatically off-limits.
106
261000
2000
aksiomatski zabranjeni.
04:38
This battery needs to be made
107
263000
2000
Bateriju treba izraditi
04:40
out of earth-abundant elements.
108
265000
2000
od elemenata kojih ima u dovoljnim količinama.
04:42
I say, if you want to make something dirt cheap,
109
267000
3000
Ja znam reći, ako nešto želite da bude prljavo jeftino,
04:45
make it out of dirt --
110
270000
2000
izradite to od prljavštine...
04:47
(Laughter)
111
272000
2000
(Smijeh)
04:49
preferably dirt
112
274000
2000
po mogućnosti od prljavštine
04:51
that's locally sourced.
113
276000
3000
koja je lokalno dostupna.
04:54
And we need to be able to build this thing
114
279000
3000
To moramo biti u stanju to izraditi
04:57
using simple manufacturing techniques and factories
115
282000
3000
pomoću jednostavnih proizvodnih tehnika i tvornica
05:00
that don't cost us a fortune.
116
285000
3000
koje nas neće koštati bogatstvo.
05:04
So about six years ago,
117
289000
2000
Prije jedno šest godina,
05:06
I started thinking about this problem.
118
291000
2000
počeo sam razmišljati o ovom problemu.
05:08
And in order to adopt a fresh perspective,
119
293000
3000
A kako bih dobio svježu perspektivu,
05:11
I sought inspiration from beyond the field of electricity storage.
120
296000
4000
tražio sam inspiraciju izvan područja pohrane el. energije.
05:15
In fact, I looked to a technology
121
300000
3000
U biti, okrenuo sam se tehnologiji
05:18
that neither stores nor generates electricity,
122
303000
3000
koja niti čuva niti stvara el. energiju,
05:21
but instead consumes electricity,
123
306000
2000
već je troši,
05:23
huge amounts of it.
124
308000
2000
u ogromnim količinama.
05:25
I'm talking about the production of aluminum.
125
310000
4000
Govorim o proizvodnji aluminija.
05:29
The process was invented in 1886
126
314000
2000
Postupak je izmišljen 1886. godine
05:31
by a couple of 22-year-olds --
127
316000
2000
od dvojce 22-godišnjaka...
05:33
Hall in the United States and Heroult in France.
128
318000
3000
Halla iz Sjedinjenih Država i Heroulta iz Francuske.
05:36
And just a few short years following their discovery,
129
321000
3000
U samo par godina nakon njihova otrkića,
05:39
aluminum changed
130
324000
2000
aluminijum je od
05:41
from a precious metal costing as much as silver
131
326000
3000
skupocijenog metala koji je koštao poput srebra
05:44
to a common structural material.
132
329000
3000
postao uobičajeni strukturni materijal.
05:47
You're looking at the cell house of a modern aluminum smelter.
133
332000
3000
Gledate u skup ćelija moderne tvornice aluminija.
05:50
It's about 50 feet wide
134
335000
2000
Široka je oko 15 metara
05:52
and recedes about half a mile --
135
337000
2000
i proteže se na gotovo jedan kilometar...
05:54
row after row of cells
136
339000
3000
red za redom ćelija
05:57
that, inside, resemble Volta's battery,
137
342000
3000
koje, unutra, sliče Voltinoj bateriji,
06:00
with three important differences.
138
345000
2000
ali s tri ključne razlike.
06:02
Volta's battery works at room temperature.
139
347000
3000
Voltina baterija radi na sobnoj temperaturi.
06:05
It's fitted with solid electrodes
140
350000
3000
Sastoji se od čvrstih elektroda
06:08
and an electrolyte that's a solution of salt and water.
141
353000
3000
i elektrolita, tj. soli otopljene u vodi.
06:11
The Hall-Heroult cell
142
356000
2000
Hall-Heroult ćelija
06:13
operates at high temperature,
143
358000
2000
radi na visokoj temperaturi,
06:15
a temperature high enough
144
360000
2000
temperaturi toliko visokoj
06:17
that the aluminum metal product is liquid.
145
362000
2000
da metal, aluminij, postaje tekući.
06:19
The electrolyte
146
364000
2000
Elektrolit
06:21
is not a solution of salt and water,
147
366000
2000
nije sol otopljena u vodi,
06:23
but rather salt that's melted.
148
368000
2000
već rastopljena sol.
06:25
It's this combination of liquid metal,
149
370000
2000
Ova kombinacija tekućeg metala,
06:27
molten salt and high temperature
150
372000
3000
rastopljene soli i visoke temperature
06:30
that allows us to send high current through this thing.
151
375000
4000
omogućava protok jake struje kroz ovu napravu.
06:34
Today, we can produce virgin metal from ore
152
379000
3000
Danas, možemo proizvesti primarni metal iz ruda
06:37
at a cost of less than 50 cents a pound.
153
382000
3000
po cijeni manjoj od 50 centi za pola kilograma.
06:40
That's the economic miracle
154
385000
2000
To je ekonomsko čudo
06:42
of modern electrometallurgy.
155
387000
2000
moderne elektrometalurgije.
06:44
It is this that caught and held my attention
156
389000
3000
To je zaokupilo moju pažnju,
06:47
to the point that I became obsessed with inventing a battery
157
392000
4000
toliko sa sam postao opsjednut izumom baterije
06:51
that could capture this gigantic economy of scale.
158
396000
4000
koja može sadržavati ovu divovsku ekonomiju razmjera.
06:55
And I did.
159
400000
2000
I to sam učinio.
06:57
I made the battery all liquid --
160
402000
3000
Izradio sam potpuno tekuću bateriju...
07:00
liquid metals for both electrodes
161
405000
2000
tekući metali za obje elektrode
07:02
and a molten salt for the electrolyte.
162
407000
2000
te rastopljena sol kao elektrolit.
07:04
I'll show you how.
163
409000
3000
Pokazat ću vam kako.
07:24
So I put low-density
164
429000
3000
Na vrh sam stavio
07:27
liquid metal at the top,
165
432000
4000
tekući metal niske gustoće,
07:31
put a high-density liquid metal at the bottom,
166
436000
6000
na dno tekući metal visoke gustoće,
07:37
and molten salt in between.
167
442000
3000
a između rastopljenu sol.
07:43
So now,
168
448000
2000
E sad,
07:45
how to choose the metals?
169
450000
3000
kako odabrati metale?
07:48
For me, the design exercise
170
453000
2000
Ze mene, vježba stvaranja
07:50
always begins here
171
455000
2000
počinje ovjde
07:52
with the periodic table,
172
457000
2000
s periodini sustavom,
07:54
enunciated by another professor,
173
459000
2000
koji je predstavio još jedan profesor,
07:56
Dimitri Mendeleyev.
174
461000
2000
Dmitri Mendeljejev.
07:58
Everything we know
175
463000
2000
Sve što znamo
08:00
is made of some combination
176
465000
2000
sastoji se od neke kombinacije
08:02
of what you see depicted here.
177
467000
3000
ovdje navedenog.
08:05
And that includes our own bodies.
178
470000
2000
Uključujući i naša tijela.
08:07
I recall the very moment one day
179
472000
3000
Sjećam se trenutka
08:10
when I was searching for a pair of metals
180
475000
3000
kad sam tražio par metala
08:13
that would meet the constraints
181
478000
2000
koji će odgovarati uvjetima
08:15
of earth abundance,
182
480000
2000
da ih ima u dovoljnim količinama,
08:17
different, opposite density
183
482000
3000
da su različite, nasuportne gutoće
08:20
and high mutual reactivity.
184
485000
2000
i visoke obostrane reaktivnosti.
08:22
I felt the thrill of realization
185
487000
2000
Bio sam oduševljen spoznavši
08:24
when I knew I'd come upon the answer.
186
489000
3000
kako sam našao odgovor.
08:29
Magnesium for the top layer.
187
494000
3000
Mangezij za gornji sloj.
08:32
And antimony
188
497000
2000
I antimon
08:34
for the bottom layer.
189
499000
3000
za donji sloj.
08:37
You know, I've got to tell you,
190
502000
2000
Znate, moram vam reći,
08:39
one of the greatest benefits of being a professor:
191
504000
3000
jedna od najboljih stavri kad ste profesor je:
08:42
colored chalk.
192
507000
2000
kreda u boji.
08:44
(Laughter)
193
509000
3000
(Smijeh)
08:47
So to produce current,
194
512000
3000
Kako bi se proizvela sruja,
08:50
magnesium loses two electrons
195
515000
2000
magnezij gubi dva elektrona,
08:52
to become magnesium ion,
196
517000
3000
i postaje magnezij ion,
08:55
which then migrates across the electrolyte,
197
520000
2000
i onda migrira po elektrolitu,
08:57
accepts two electrons from the antimony,
198
522000
3000
uzima dva elektrona od antimona,
09:00
and then mixes with it to form an alloy.
199
525000
3000
te ih mješa u obliku legure.
09:03
The electrons go to work
200
528000
2000
Elektroni kreću raditi
09:05
in the real world out here,
201
530000
3000
u stavrni svijet,
09:08
powering our devices.
202
533000
3000
napajajući naše uređaje.
09:14
Now to charge the battery,
203
539000
3000
Za punjenje baterije,
09:17
we connect a source of electricity.
204
542000
3000
priključimo se na izvor el. energije.
09:20
It could be something like a wind farm.
205
545000
3000
To može biti nešto poput vjetroparka.
09:24
And then we reverse the current.
206
549000
4000
I onda okrećemo struju.
09:28
And this forces magnesium to de-alloy
207
553000
5000
A to prisiljava magnezij da rastvori leguru
09:33
and return to the upper electrode,
208
558000
3000
i vrati se gornjoj elektrodi,
09:36
restoring the initial constitution of the battery.
209
561000
5000
vraćajući početni sastav baterije.
09:41
And the current passing between the electrodes
210
566000
3000
Struja koja prolazi izmešu elektroda
09:44
generates enough heat to keep it at temperature.
211
569000
3000
stvara dovoljno topline da je drži na odgovarajućoj temperaturi.
09:47
It's pretty cool,
212
572000
3000
Super,
09:50
at least in theory.
213
575000
2000
barem u teoriji.
09:52
But does it really work?
214
577000
2000
Ali djeluje li to zapravo?
09:54
So what to do next?
215
579000
2000
Što uraditi sljedeće?
09:56
We go to the laboratory.
216
581000
2000
Idemo u laboratorij.
09:58
Now do I hire seasoned professionals?
217
583000
4000
Zapošljavam li iskusne profesionalce?
10:02
No, I hire a student
218
587000
3000
Ne, već studenta
10:05
and mentor him,
219
590000
2000
kojeg podučavam,
10:07
teach him how to think about the problem,
220
592000
3000
učim ga kako razmišljati o problemu,
10:10
to see it from my perspective
221
595000
2000
da ga sagleda iz moje perspektive
10:12
and then turn him loose.
222
597000
2000
i onda ga puštam.
10:14
This is that student, David Bradwell,
223
599000
2000
Ovo je taj student, David Bradwell,
10:16
who, in this image,
224
601000
2000
koji se, na ovoj slici,
10:18
appears to be wondering if this thing will ever work.
225
603000
3000
pita hoće li ova stvar ikad raditi.
10:21
What I didn't tell David at the time
226
606000
2000
Tad to nisam rekao Davidu,
10:23
was I myself wasn't convinced it would work.
227
608000
3000
ali ni ja nisam bio uvjeren da hoće.
10:26
But David's young and he's smart
228
611000
2000
Ali, David je mlad i pametan,
10:28
and he wants a Ph.D.,
229
613000
2000
želi doktorirati
10:30
and he proceeds to build --
230
615000
2000
i nastavio je s izradom...
10:32
(Laughter)
231
617000
2000
(Smijeh)
10:34
He proceeds to build
232
619000
2000
Nastavio je s izradom
10:36
the first ever liquid metal battery
233
621000
2000
prve tekuće baterije
10:38
of this chemistry.
234
623000
2000
ovog kemijskog sastava.
10:40
And based on David's initial promising results,
235
625000
3000
A temeljem početnih Davidovih obečavajućih rezultata,
10:43
which were paid
236
628000
2000
koji su plaćeni
10:45
with seed funds at MIT,
237
630000
3000
sredstvima MIT-a,
10:48
I was able to attract major research funding
238
633000
3000
uspio sam privuči glavne ulagače u istraživanja
10:51
from the private sector
239
636000
2000
iz privatnog sektora
10:53
and the federal government.
240
638000
2000
i savezne vlasti.
10:55
And that allowed me to expand my group to 20 people,
241
640000
3000
A to mi je omogućilo proširivanje tima na 20 ljudi,
10:58
a mix of graduate students, post-docs
242
643000
2000
kombinacija diplomaca, postdoktoranata
11:00
and even some undergraduates.
243
645000
2000
pa čak i nekih dodiplomaca.
11:02
And I was able to attract really, really good people,
244
647000
3000
Uspio sam privuči neke zaista dobre ljude,
11:05
people who share my passion
245
650000
2000
ljude koji dijele moju strast
11:07
for science and service to society,
246
652000
2000
za znanošću i služenju društvu,
11:09
not science and service for career building.
247
654000
4000
a ne znanosti i stjecanju karijere.
11:13
And if you ask these people
248
658000
2000
I ako upitate ove ljude
11:15
why they work on liquid metal battery,
249
660000
2000
zašto rade na tekućoj bateriji,
11:17
their answer would hearken back
250
662000
2000
njihov odgovor parafrazirat će
11:19
to President Kennedy's remarks
251
664000
2000
govor predsjenika Kennedyja
11:21
at Rice University in 1962
252
666000
3000
na Sveučilištu Rice 1962. godine
11:24
when he said -- and I'm taking liberties here --
253
669000
2000
kad je rekao...u slobodnoj interpretaciji...
11:26
"We choose to work on grid-level storage,
254
671000
2000
"Odabiremo raditi na pohrani na mrežnoj razini,
11:28
not because it is easy,
255
673000
2000
ne zato što je to lako,
11:30
but because it is hard."
256
675000
2000
već zato što je to teško."
11:32
(Applause)
257
677000
6000
(Pljesak)
11:39
So this is the evolution of the liquid metal battery.
258
684000
3000
Ovo je evolucija tekuće baterije.
11:42
We start here with our workhorse one watt-hour cell.
259
687000
3000
Započeli smo s temeljnom ćelijom od jednog watt-sata.
11:45
I called it the shotglass.
260
690000
2000
Ja je zovem bićerin.
11:47
We've operated over 400 of these,
261
692000
3000
Radili smo na preko 400 takvih,
11:50
perfecting their performance with a plurality of chemistries --
262
695000
3000
usavršavali njihove performanse s brojnim kemijskim spojevima...
11:53
not just magnesium and antimony.
263
698000
2000
ne samo magenzijem i antimonom.
11:55
Along the way we scaled up to the 20 watt-hour cell.
264
700000
3000
S vremenom smo došli do ćelije od 20 watt-sata.
11:58
I call it the hockey puck.
265
703000
2000
Zovem je hokejski pak.
12:00
And we got the same remarkable results.
266
705000
2000
I dobili smo jednako zadivljujuće rezultate.
12:02
And then it was onto the saucer.
267
707000
2000
A potom je došao tanjur.
12:04
That's 200 watt-hours.
268
709000
2000
To je 200 watt-sati.
12:06
The technology was proving itself
269
711000
2000
Tehnlogija se pokazala
12:08
to be robust and scalable.
270
713000
3000
robusnom i skalabilnom.
12:11
But the pace wasn't fast enough for us.
271
716000
2000
Ali ritam nije bio dovoljno brz za nas.
12:13
So a year and a half ago,
272
718000
2000
Pa smo prije godinu i pol,
12:15
David and I,
273
720000
2000
David i ja,
12:17
along with another research staff-member,
274
722000
2000
zajendo s ostalim članovima istraživačkog tima,
12:19
formed a company
275
724000
2000
osnovali tvrtku
12:21
to accelerate the rate of progress
276
726000
2000
kako bismo ubrzali postupak napretka
12:23
and the race to manufacture product.
277
728000
2000
i utrku za izradu proizvoda.
12:25
So today at LMBC,
278
730000
2000
Tako danas u LMBC,
12:27
we're building cells 16 inches in diameter
279
732000
2000
izrađujemo ćelije od 40 cm u promjeru
12:29
with a capacity of one kilowatt-hour --
280
734000
2000
kapaciteta jednog kilowatt-sata...
12:31
1,000 times the capacity
281
736000
3000
1000 puta kapaciteta
12:34
of that initial shotglass cell.
282
739000
2000
one početne, "bićerin" ćelije.
12:36
We call that the pizza.
283
741000
2000
Zovemo je pizza.
12:38
And then we've got a four kilowatt-hour cell on the horizon.
284
743000
3000
A onda je u planu bila ćelija od četiri kilowatt-sata.
12:41
It's going to be 36 inches in diameter.
285
746000
2000
Imat će promjer od 90 cm.
12:43
We call that the bistro table,
286
748000
2000
Zovemo je restoranski stol,
12:45
but it's not ready yet for prime-time viewing.
287
750000
2000
ali još nije spremna za gledanje u udarnom terminu.
12:47
And one variant of the technology
288
752000
2000
A jedna varijanta tehnologije
12:49
has us stacking these bistro tabletops into modules,
289
754000
4000
omogućila nam je slaganje ovih restoranskih stolova u module,
12:53
aggregating the modules into a giant battery
290
758000
3000
agregirajući module u divovsku bateriju
12:56
that fits in a 40-foot shipping container
291
761000
2000
koja stane u kontejner za prijevoz od 36 m,
12:58
for placement in the field.
292
763000
2000
koji se može postaviti u polje.
13:00
And this has a nameplate capacity of two megawatt-hours --
293
765000
3000
A ima nominalni kapacitet od dva megawatt-sata...
13:03
two million watt-hours.
294
768000
2000
dva milijuna watt-sati.
13:05
That's enough energy
295
770000
2000
To je dovoljno energije
13:07
to meet the daily electrical needs
296
772000
2000
za zadovoljavanje dnevnih potreba za el. energijom
13:09
of 200 American households.
297
774000
2000
200 američkih kućanstava.
13:11
So here you have it, grid-level storage:
298
776000
3000
I evo je, pohrana na mrežnoj razini:
13:14
silent, emissions-free,
299
779000
3000
tiha, bez otpadnih plinova,
13:17
no moving parts,
300
782000
2000
bez pokretnih dijelova,
13:19
remotely controlled,
301
784000
2000
daljinski upravljana,
13:21
designed to the market price point
302
786000
3000
dizajnirana prema tržišnoj cijeni
13:24
without subsidy.
303
789000
3000
bez subvencija.
13:27
So what have we learned from all this?
304
792000
2000
Što smo iz ovog naučiti?
13:29
(Applause)
305
794000
6000
(Pljesak)
13:35
So what have we learned from all this?
306
800000
2000
Što smo iz ovog naučili?
13:37
Let me share with you
307
802000
2000
Podijelit ću s vama
13:39
some of the surprises, the heterodoxies.
308
804000
3000
neka od iznenađenja, heterodoksije.
13:42
They lie beyond the visible.
309
807000
2000
Sve se to nalazi onkraj vidljivog.
13:44
Temperature:
310
809000
2000
Temperatura:
13:46
Conventional wisdom says set it low,
311
811000
2000
Uvriježeni stav smatra da je treba podesiti na niske vrijednosti
13:48
at or near room temperature,
312
813000
2000
ili oko sobne temperature,
13:50
and then install a control system to keep it there.
313
815000
3000
a potom treba instalirati kontrolni sustav koji će je održavati.
13:53
Avoid thermal runaway.
314
818000
2000
Treba izbjegavati velike termalne oscilacije.

ABOUT THE SPEAKER
Donald Sadoway - Materials engineerDonald Sadoway is working on a battery miracle -- an inexpensive, incredibly efficient, three-layered battery using “liquid metal."
Why you should listen
The problem at the heart of many sustainable-energy systems: How to store power so it can be delivered to the grid all the time, day and night, even when the wind's not blowing and the sun's not shining? At MIT, Donald Sadoway has been working on a grid-size battery system that stores energy using a three-layer liquid-metal core. With help from fans like Bill Gates, Sadoway and two of his students have spun off the Liquid Metals Battery Corporation (LMBC) to bring the battery to market.
