ABOUT THE SPEAKER
Eric Giler - Wireless electrician
As the CEO of MIT-inspired WiTricity, Eric Giler has a plan to beam electric power through the air to wirelessly power your laptop or recharge your car. You may never plug in again.

Why you should listen

Eric Giler heads WiTricity, a startup with a product straight out of science fiction: wireless electricity, beamed from a base station to your electrical devices. The technology was developed by an MIT team led by theoretical physicist Marin Soljačić (who won a MacArthur "genius"grant last year). Now, WiTricity is one of several startups developing tech to safely transmit power through the air -- and potentially untether our electronic age.

The technology at the core of WiTricity's approach is called magnetic coupled resonance, which can provoke an energetic response at a distance between two coils, one powered, the other not. If the two coils are correctly tuned to one another, energy flows from the connected one (installed, say, on the ceiling of a room) into the other (inside, say, your laptop). Giler presented a demo of it at TEDGlobal  2009 -- and several companies are already planning to add it to their phones, cameras, TVs and other devices.

Primele viziuni despre energia fara fir
00:16
actuallyde fapt were thought of by NikolaNikola TeslaTesla
1

3000
au fost gandite de Nikola Tesla
00:19
basicallype scurt about 100 yearsani agoîn urmă.
2
7000
2000
acum aproximativ 100 de ani.
00:21
The thought that
3
9000
2000
Gandul ca
00:23
you wouldn'tnu ar fi want to transfertransfer electricelectric powerputere wirelesslyfără fir,
4
11000
3000
ca n-ati dori sa transferati energie electrica fara a folosi fire
00:26
no one ever thought of that.
5
14000
2000
nimeni nu s-a gandit la asta.
00:28
They thought, "Who would use it if you didn't?"
6
16000
2000
S-au gandit, "Cine o va folosi daca voi nu?"
00:30
And so, in factfapt, he actuallyde fapt seta stabilit about
7
18000
3000
Si astfel, de fapt, s-a pus
00:33
doing a varietyvarietate of things.
8
21000
2000
sa faca o multime de lucruri.
00:35
BuiltConstruit the TeslaTesla coilbobina. This towerturn was builtconstruit
9
23000
2000
A construit clopotul Tesla. Acest turn a fost construit
00:37
on Long IslandInsula back at the beginningînceput of the 1900s.
10
25000
4000
in Long Island la inceputul anilor 1900.
00:41
And the ideaidee was, it was supposedpresupus to be ablecapabil to transfertransfer powerputere
11
29000
2000
Iar ideea era, ca aceasta se presupunea a fi capabila sa transfere curent
00:43
anywhereoriunde on EarthPământ.
12
31000
2000
oriunde in lume.
00:45
We'llVom never know if this stuffchestie workeda lucrat. ActuallyDe fapt, I think the
13
33000
2000
Nu vom sti daca aceasta treaba a functionat. De fapt cred ca

00:51
sometimecândva in the earlydin timp 1900s.
16
39000
3000
undeva la inceputul anilor 1900.
00:54
But the one thing that did come out of electricityelectricitate
17
42000
2000
Dar un lucru care a rezultat din electricitate
00:56
is that we love this stuffchestie so much.
18
44000
2000
este ca iubim treaba asta foarte mult.
00:58
I mean, think about how much we love this.
19
46000
2000
Ganditi-va cat de mult ne place ideea asta.
01:00
If you just walkmers pe jos outsidein afara, there are trillionstrilioane of dollarsdolari

01:06
puttingpunând up wiresfire to get powerputere from where it's createdcreată
22
54000
3000
in fire, pentru a duce electricitatea din locul unde este creata
01:09
to where it's used.
23
57000
2000
acolo unde este folosita.
01:11
The other thing is, we love batteriesbaterii.
24
59000
3000
O alta chestiune este ca ne plac bateriile.
01:14
And for those of us that have an environmentalde mediu elementelement to us,
25
62000
4000
Si pentru cei dintre noi care sunt atinsi de microbul ecologiei
01:18
there is something like 40 billionmiliard
26
66000
2000
se produc aproximativ 40 de miliarde
01:20
disposableunica folosinta batteriesbaterii builtconstruit everyfiecare yearan
27
68000
2000
de baterii in fiecare an.
01:22
for powerputere that, generallyîn general speakingvorbitor,
28
70000
2000
Pentru o energie care, vorbind in general,
01:24
is used withinîn a fewpuțini inchesinch or a fewpuțini feetpicioare
29
72000
3000
provine din cativa inchi sau cateva picioare
01:27
of where there is very inexpensiveieftin powerputere.
30
75000
2000
este o energie foarte ieftina.
01:29
So, before I got here,
31
77000
3000
Asa ca inainte de a veni aici,
01:32
I thought, "You know, I am from NorthNord AmericaAmerica.
32
80000
2000
m-am gandit, "Sunt din America de Nord.
01:34
We do have a little bitpic of a reputationreputatie in the UnitedMarea StatesStatele."
33
82000
3000
Avem o reputatie proasta in Statele Unite"
01:37
So I thought I'd better look it up first.
34
85000
2000
Asa ca ar fi mai bine sa analizez situatia de aici in primul rand.
01:39
So definitiondefiniție numbernumăr sixşase is the NorthNord AmericanAmerican
35
87000
3000
Definitia numarul sase este definitia Nord Americana
01:42
definitiondefiniție of the wordcuvânt "sucka suge."
36
90000
3000
a cuvantului "a absorbi".
01:45
WiresFire sucka suge, they really do.
37
93000
2000
Firele absorb si ne exaspereaza, intradevar.
01:47
Think about it. WhetherDacă that's you in that pictureimagine
38
95000
3000
Ganditi-va numai. Chiar daca sunteti voi in poza aceea
01:50
or something undersub your deskbirou.
39
98000
2000
sau ceva sub birou.
01:52
The other thing is, batteriesbaterii sucka suge too.
40
100000
3000
Alta chestiune este ca si bateriile ne exaspereaza.
01:55
And they really, really do.
41
103000
2000
Si ele intradevar o fac.
01:57
Do you ever wondermirare what happensse întâmplă to this stuffchestie?
42
105000
2000
V-ati intrebat vreodata ce se intampla cu ele?
01:59
40 billionmiliard of these things builtconstruit.
43
107000
2000
Cu cele 40 de miliarde produse?
02:01
This is what happensse întâmplă.
44
109000
2000
Asta se intampla.
02:03
They fallcădea apartseparat, they disintegratese dezintegreze,
45
111000
2000
Ele se descarca, se desintegreaza,
02:05
and they endSfârşit up here.
46
113000
2000
si in final ajung aici.
02:07
So when you talk about expensivescump powerputere,
47
115000
3000
Deci atunci cand vorbiti de energie scumpa
02:10
the costa costat perpe kilowatt-hourkilowatt-oră
48
118000
4000
costul pe kilowatul ora
02:14
to supplylivra batterybaterie powerputere to something
49
122000
2000
pentru a alimenta cu baterii ceva
02:16
is on the orderOrdin of two to threeTrei hundredsută poundslire sterline.
50
124000
3000
este de ordinul a una doua sute de kilograme.
02:19
Think about that.
51
127000
2000
Ganditi-va la asta.
02:21
The mostcel mai expensivescump gridgrilă powerputere in the worldlume
52
129000
2000
Cea mai scumpa retea energetica din lume
02:23
is thousandthsmiimi of that.
53
131000
3000
sunt mii de asemenea lucruri.
02:26
So fortunatelydin fericire, one of the other definitionsdefiniții
54
134000
3000
Din fericire, una din celelalte definitii
02:29
of "sucka suge" that was in there, it does createcrea a vacuumvid.
55
137000
3000
a cuvantului a absorbi care se gaseste aici, este ceva ce creeaza un vid.
02:32
And naturenatură really does abhororoare a vacuumvid.
56
140000
3000
Si natura intradevar uraste vidul.
02:35
What happeneds-a întâmplat back a fewpuțini yearsani agoîn urmă
57
143000
2000
Ce s-a intampla acum cativa ani
02:37
was a groupgrup of theoreticalteoretic physicistsfizicienii at MITMIT
58
145000
4000
a fost ca un grup de fizicieni teoretici ai MIT
02:41
actuallyde fapt camea venit up with this conceptconcept of transferringtransferul powerputere over distancedistanţă.
59
149000
4000
au venit cu acest concept de transferare a energiei la distanta.
02:45
BasicallyPractic they were ablecapabil to lightușoară a 60 wattWatt lightușoară bulbbec
60
153000
4000
Ei au reusit sa aprinda un bec de 60 de wati
02:49
at a distancedistanţă of about two metersmetri.
61
157000
2000
la o distanta de aproximativ 2 metri.
02:51
It got about 50 percentla sută of the efficiencyeficienţă --
62
159000
3000
Le-a luat, aproximativ 50 de procente din eficienta.
02:54
by the way, that's still a couplecuplu thousandmie timesori
63
162000
2000
Apropo, acest lucru este de mii de ori
02:56
more efficienteficient than a batterybaterie would be, to do the samela fel thing.
64
164000
3000
mai eficient decat ar putea sa faca acelasi lucru, o baterie.
02:59
But were ablecapabil to lightușoară that,
65
167000
2000
Dar am fost capabili sa aprindem becul,
03:01
and do it very successfullycu succes.
66
169000
2000
si am facut-o cu foarte mare succes.
03:03
This was actuallyde fapt the experimentexperiment. So you can see
67
171000
2000
A fost un experiment. Puteti vedea
03:05
the coilsbobine were somewhatoarecum largermai mare.
68
173000
3000
ca bobinele au fost intrucatva mari.
03:08
The lightușoară bulbbec was a fairlydestul de simplesimplu tasksarcină, from theiral lor standpointpunct de vedere.
69
176000
3000
Becul a fost o sarcina usoara din punctul lor de vedere.
03:11
This all camea venit from a professorProfesor
70
179000
3000
Toate astea au pornit de la un profesor
03:14
wakingstarea de veghe up at night to the thirdal treilea night in a rowrând
71
182000
2000
care se trezea noaptea, trei nopti la rand
03:16
that his wife'ssoţia lui cellphonetelefon mobil was beepingbip
72
184000
2000
pentru ca celularul sotiei beep-aia
03:18
because it was runningalergare out of batterybaterie powerputere.
73
186000
3000
pentru ca nu mai avea baterie.
03:21
And he was thinkinggândire, "With all the electricityelectricitate that's out there in the wallspereți,
74
189000
4000
Si el s-a gandit: "Cu toata energia care se gaseste in peretii casei
03:25
why couldn'tnu a putut some of that just come into the phonetelefon so I could get some sleepdormi?"
75
193000
3000
de ce nu am putea face ca o parte din ea sa intre in telefon ca sa pot si eu dormi linistit?"
03:28
And he actuallyde fapt camea venit up with this conceptconcept
76
196000
2000
Si a realizat acest concept
03:30
of resonantrezonanță energyenergie transfertransfer.
77
198000
2000
al transferului rezonant al energiei.
03:32
But insideinterior a standardstandard transformertransformator are two coilsbobine of wiresârmă.
78
200000
4000
Dar inauntrul unui transformator sunt doua spirale de fire.
03:36
And those two coilsbobine of wiresârmă are really, really closeînchide to eachfiecare other,
79
204000
3000
Iar aceste spirale din fire sunt foarte foarte aproape una de alta,
03:39
and actuallyde fapt do transfertransfer powerputere
80
207000
4000
si realizeaza transferul de energie --
03:43
magneticallymagnetic and wirelesslyfără fir, only over a very shortmic de statura distancedistanţă.
81
211000
3000
magnetic si fara fire, doar pe o distanta scurta.
03:46
What DrDr. SoljacicSoljacic figuredimaginat out how to do
82
214000
3000
Ce si-a imaginat Dr. Soljacic a fost
03:49
was separatesepara the coilsbobine in a transformertransformator
83
217000
3000
separarea spirelor dintr-un transformator
03:52
to a greatermai mare distancedistanţă than the sizemărimea of those transformerstransformatoare
84
220000
4000
la o distanta mai mare decat marimea acelor transformatoare
03:56
usingutilizând this technologytehnologie, whichcare is not dissimilardiferit
85
224000
2000
utilizand aceasta tehnologie, care nu este deosebita
03:58
from the way an operaoperă singercântăreaţă shatterssparge a glasssticlă on the other sidelatură of the roomcameră.
86
226000
4000
fata de modul in care un cantaret de opera zdruncina un pahar in cealalta parte a camerei.
04:02
It's a resonantrezonanță phenomenonfenomen
87
230000
2000
Este un fenomen rezonant
04:04
for whichcare he actuallyde fapt receivedprimit a MacArthurMarinica FellowshipFellowship AwardPremiul,
88
232000
3000
pentru care a primit Distinctia MacArthur Fellowship,
04:07
whichcare is nicknamedporeclit the GeniusGeniu AwardPremiul,
89
235000
2000
care este poreclita Distinctia Geniului
04:09
last SeptemberSeptembrie, for his discoverydescoperire.
90
237000
3000
in Septembrie anul trecut.
04:12
So how does it work?
91
240000
2000
Cum functioneaza?
04:14
ImagineImaginaţi-vă a coilbobina. For those of you that are engineersingineri,
92
242000
3000
Imaginati-va o spira. Pentu cei care sunt ingineri,
04:17
there's a capacitorCondensator attachedatașat to it too.
93
245000
2000
exista un condensator atasat la el.
04:19
And if you can causecauza that coilbobina to resonaterezonează,
94
247000
3000
Si pentru ca puteti face o spira sa rezoneze,
04:22
what will happenîntâmpla is it will pulsepuls
95
250000
2000
ce se va intampla este ca ea va pulsa,
04:24
at alternatingalternativ currentactual frequenciesfrecvenţele --
96
252000
2000
la alternarea frecventelor,
04:26
at a fairlydestul de highînalt frequencyfrecvență, by the way.
97
254000
3000
la o mult mai inalta frecventa, printre altele.
04:29
And if you can bringaduce anothero alta devicedispozitiv
98
257000
4000
Si daca puteti aduce un alt dispozitiv
04:33
closeînchide enoughdestul to the sourcesursă,
99
261000
2000
suficient de aproape de sursa,
04:35
that will only work at exactlyexact that frequencyfrecvență,
100
263000
3000
acesta va functiona exact la aceeasi frecventa,
04:38
you can actuallyde fapt get them to do what's calleddenumit stronglytare couplecuplu,
101
266000
4000
le veti putea face sa lucreze precum un cuplu,
04:42
and transfertransfer magneticmagnetic energyenergie betweenîntre them.
102
270000
4000
si sa transfere energie magnetica intre ele.
04:46
And then what you do is, you startstart out with electricityelectricitate,
103
274000
2000
Si atunci ceea ce faceti este, incepeti cu electricitatea,
04:48
turnviraj it into magneticmagnetic fieldcamp, take that magneticmagnetic fieldcamp,
104
276000
2000
o transformati in camp magnetic, luati campul magnetic,
04:50
turnviraj it back into electricityelectricitate,
105
278000
2000
si il trasnformati inapoi in electricitate.
04:52
and then you can use it.
106
280000
3000
Si apoi puteti s-o folositi.
04:55
NumberNumărul one questionîntrebare I get askedîntrebă.
107
283000
2000
Intrebarea numarul unu a fost pusa.
04:57
I mean, people are worriedîngrijorat about cellphonestelefoane mobile beingfiind safesigur.
108
285000
2000
Oamenii sunt ingrijorati ca telefoanele celulare sa fie sigure.
04:59
You know. What about safetySiguranță?
109
287000
2000
Stiti. Ce se poate spune despre siguranta?
05:01
The first thing is this is not a "radiativeradiativ" technologytehnologie.
110
289000
2000
Primul lucru este ca nu este o tehnologie radiativa.
05:03
It doesn't radiateradia.
111
291000
2000
Nu radiaza.
05:05
There aren'tnu sunt electricelectric fieldscâmpuri here. It's a magneticmagnetic fieldcamp.
112
293000
3000
Nu exista camp electic aici. Este un camp magnetic.
05:08
It stayssejururi withinîn eitherfie what we call the sourcesursă,
113
296000
2000
Sta inauntrul a ceea ce noi numim sursa,
05:10
or withinîn the devicedispozitiv.
114
298000
2000
sau a dispozitivului.
05:12
And actuallyde fapt, the magneticmagnetic fieldscâmpuri we're usingutilizând
115
300000
2000
Campul magnetic care este folosit
05:14
are basicallype scurt about the samela fel as the Earth'sPământului magneticmagnetic fieldcamp.
116
302000
3000
este similar campului magnetic al Pamantului.
05:17
We livetrăi in a magneticmagnetic fieldcamp.
117
305000
2000
Noi traim intr-un camp magnetic.
05:19
And the other thing that's prettyfrumos coolmisto about the technologytehnologie is
118
307000
3000
Iar alt lucru interesant despre aceasta tehnologie este
05:22
that it only transferstransferuri energyenergie to things that work at exactlyexact the samela fel frequencyfrecvență.
119
310000
4000
ca transfera energie doar lucrurilor care lucreaza la exact aceeasi frecventa.
05:26
And it's virtuallypractic impossibleimposibil in naturenatură to make that happenîntâmpla.
120
314000
4000
si este imposibil in natura, ca asa ceva sa se intample.
05:30
Then finallyin sfarsit we have governmentalguvernamental bodiesorganisme everywherepretutindeni
121
318000
2000
Si avem organisme guvernamentale peste tot
05:32
that will regulatereglementa everything we do.
122
320000
2000
care vor reglementa orice am face noi.
05:34
They'veLe-am prettyfrumos much seta stabilit fieldcamp exposureexpunerea limitslimite,

06:06
because there is a matmat on the floorpodea that's pluggedconectat into the wallperete.

By the way, I do make it look a little bitpic easierMai uşor than it is.

Dar ceea ce se va intampla este ca voi crea un camp,
06:58
It will causecauza one to get createdcreată

And if the demodemo godszei are willingdispus,
155

Si daca vor vrea zeii demostratiilor,
07:05
in about 10 secondssecunde or so we should see it.
156
413000
2000
in aproximativ 10 secunde il vom vedea.
07:07
The 10 secondssecunde actuallyde fapt are because we --
157
415000
2000
Cele 10 secunde sunt din cauza ca noi --
07:09
I don't know if any of you have ever thought about pluggingConectarea a T.V. in
158
417000
3000
Nu stiu daca unul dintre voi sa gandit la a conecta un TV
07:12
when you use just a cordcordon.
159
420000
2000
cand folositi doar un cablu.
07:14
GenerallyÎn general, you have to go over and hitlovit the buttonbuton. So I thought
160
422000
2000
In general trebuie sa mai apasati pe un buton. Asa ca m-am gandit
07:16
we put a little computercomputer in it that has to waketrezi up
161
424000
2000
am pus un mic computer in el care va trebui sa-l porneasca
07:18
to tell it to do that.
162
426000
4000
care va trebui sa-l porneasca si sa-i spuna sa faca asta.
07:26
So, I'll plugdop that in.
163
434000
2000
Asa ca-l voi conecta.
07:28
It createscreează a magneticmagnetic fieldcamp here.
164

Creeaza un camp magnetic aici.
07:31
It causescauze one to be createdcreată out here.
165

El creaza inca unul aici.
07:33
And as I said, in sortfel of about 10 secondssecunde
166

Stiti ca cei de la Apple nu te lasa prea usor sa intri in interiorul telefoanelor lor.
09:04
So we put a little sleevemaneca on the back,
198
532000
2000
Asa ca noi i-am pus o manecuta pe spate.
09:06
but we should be ablecapabil to get this guy to waketrezi up too.

09:23
and it probablyprobabil beepsbeep-uri, actuallyde fapt, as it goesmerge on as well.

ABOUT THE SPEAKER
Eric Giler - Wireless electrician
As the CEO of MIT-inspired WiTricity, Eric Giler has a plan to beam electric power through the air to wirelessly power your laptop or recharge your car. You may never plug in again.

Why you should listen

Eric Giler heads WiTricity, a startup with a product straight out of science fiction: wireless electricity, beamed from a base station to your electrical devices. The technology was developed by an MIT team led by theoretical physicist Marin Soljačić (who won a MacArthur "genius"grant last year). Now, WiTricity is one of several startups developing tech to safely transmit power through the air -- and potentially untether our electronic age.

The technology at the core of WiTricity's approach is called magnetic coupled resonance, which can provoke an energetic response at a distance between two coils, one powered, the other not. If the two coils are correctly tuned to one another, energy flows from the connected one (installed, say, on the ceiling of a room) into the other (inside, say, your laptop). Giler presented a demo of it at TEDGlobal  2009 -- and several companies are already planning to add it to their phones, cameras, TVs and other devices.
