This is a work in process,

Ito po ay isang patuloy na proyekto
00:16
based on some comments that were made
1

hango sa mga komento na binigay
00:19
at TED two years ago
2
7000
1000
sa TED noong dalawang taon na ang nakalipas
00:20
about the need for the storage of vaccine.

(Video) Narrator: On this planet,
5
13000
1000
[ Sa planetang ito ]
00:26
1.6 billion people
6
14000
2000
[ 1.6 bilyong katao ]
00:28
don't have access to electricity,
7
16000
2000
[ ang walang kuryente ]
00:30
refrigeration
8
18000
4000
[ refrigeration ]
00:34
or stored fuels.
9
22000
2000
[ o gaas ]
00:38
This is a problem.
10
26000
2000
[ ito ay isang dagok ]
00:40
It impacts:
11
28000
2000
[ at nakakaapekto: ]
00:44
the spread of disease,
12
32000
2000
[ sa paglaganap ng sakit ]
00:46
the storage of food and medicine
13
34000
3000
[ sa pag-iimbak ng pagkain at medisina ]
00:49
and the quality of life.
14
37000
3000
[ at sa kalidad ng buhay ]
00:52
So here's the plan: inexpensive refrigeration that doesn't use electricity,
15
40000
3000
[ kaya ito ang mungkahi: murang refrigeration na hindi ginagamitan ng kuryente ... ]
00:55
propane, gas, kerosene or consumables.
16
43000
5000
[ ... propane, gasolina, gaas, o mga consumables ]
01:00
Time for some thermodynamics.
17
48000
2000
[ oras na para sa kaunting thermodynamics ]
01:02
And the story of the Intermittent Absorption Refrigerator.
18
50000
3000
[ At ang kuwento ng Intermitent Absorption Refrigerator ]
01:05
Adam Grosser: So 29 years ago, I had this thermo teacher
19
53000
3000
29 na taon na ang nakalipas, may guro ako sa thermodynamics
01:09
who talked about absorption and refrigeration.
20
57000
1000
na nagbanggit tungkol sa absorption at refrigeration.
01:10
It's one of those things that stuck in my head.
21
58000
2000
Iyon ang ilan sa mga bagay na tumatak sa aking isipan.
01:12
It was a lot like the Stirling engine:
22
60000
1000
Tulad siya sa Stirling Engine:
01:13
it was cool, but you didn't know what to do with it.
23
61000
2000
astig pero hindi mo alam ang paggagamitan
01:16
And it was invented in 1858, by this guy Ferdinand Carre,
24
64000
3000
At ito ay naimbento noong 1858 ni Ferdinand Carre,
01:19
but he couldn't actually build anything with it
25
67000
1000
ngunit wala siyang magawa dito
01:20
because of the tools of the time.
26
68000
3000
dahil sa kakulangan ng kasangkapan noong panahong iyon.
01:23
This crazy Canadian named Powel Crosley
27
71000
3000
Isang nahihibang na Canadian sa ngalan na Powell Crosley
01:27
commercialized this thing called the IcyBall in 1928,
28
75000
2000
ang nagsakomersyo ng tinatawag na Icyball noong 1928,
01:29
and it was a really neat idea,
29
77000
2000
at iyon ay isang napakagandang ideya,
01:31
and I'll get to why it didn't work,
30
79000
1000
at sasabihin ko mamaya kung bakit ito'y hindi naging posible,
01:32
but here's how it works.
31
80000
1000
pero ganito ang kanyang mekanismo.
01:34
There's two spheres and they're separated in distance.
32
82000
2000
May dalawang bilog na magkahiwalay.
01:36
One has a working fluid, water and ammonia,
33
84000
2000
Laman ng isa ay working fluid, tubig at ammonia,
01:39
and the other is a condenser.
34
87000
1000
samantalang ang isa ay condenser.
01:40
You heat up one side, the hot side.
35
88000
2000
Paiinitan mo ang isang bahagi, yung mainit na bahagi.
01:42
The ammonia evaporates
36
90000
1000
Mag-eevaporate ang ammonia
01:43
and it re-condenses in the other side.
37
91000
2000
at magrerecondense sa kabilang bahagi.
01:46
You let it cool to room temperature,
38
94000
1000
Hahayaang lumamig sa room temperature,
01:47
and then, as the ammonia re-evaporates and combines with the water
39
95000
4000
at pagkatapos, habang nag-eevaporate ang ammonia kasabay ng tubig
01:51
back on the erstwhile hot side,
40
99000
1000
pabalik sa mainit na bahagi,
01:52
it creates a powerful cooling effect.
41
100000
2000
lumilikha ito ng paglamig.
01:55
So, it was a great idea that didn't work at all: it blew up.
42
103000
3000
Magandang ideya sana ngunit hindi ito naging posible: ito'y sumasabog.
01:58
Because using ammonia you get hugely high pressures
43
106000
5000
Dahil sa paggamit ng ammonia, nakakalikha ng matataas na pressures
02:03
if you heated them wrong.
44
111000
1000
kapag mali ang paraan ng pag-init.
02:04
It topped 400 psi. The ammonia was toxic. It sprayed everywhere.
45
112000
4000
Aabot ito ng 400 psi. Nakakalason ang ammonia. Kumakalat sa paligid.
02:08
But it was kind of an interesting thought.
46
116000
2000
Ngunit talagang interesante ang ideyang iyon.
02:10
So, the great thing about 2006 is
47
118000
3000
Kaya, naging mabuti ang 2006 dahil
02:13
there's a lot of really great computational work you can do.
48
121000
3000
maraming computational work ang maaring gawin.
02:16
So, we got the whole thermodynamics department
49
124000
3000
Kaya, tinipon namin ang buong departamento ng thermodynamics
02:19
at Stanford involved --
50
127000
1000
sa Stanford.
02:20
a lot of computational fluid dynamics.
51
128000
1000
Maraming computational fluid dynamics.
02:22
We proved that most of the ammonia refrigeration tables are wrong.
52
130000
3000
Pinatunayan naming mali ang karamihan ng ammonia refrigeration tables.
02:25
We found some non-toxic refrigerants
53
133000
3000
Nakadiskubre kami ng refrigerants na hindi nakakalason
02:28
that worked at very low vapor pressures.
54
136000
1000
na maaring gamitin sa mabababang vapor pressures.
02:29
Brought in a team from the U.K. --
55
137000
3000
Humingi kami ng tulong sa isang grupo mula UK --
02:32
there's a lot of great refrigeration people,
56
140000
1000
maraming eksperto sa refrigeration,
02:33
it turned out, in the U.K. --
57
141000
2000
napag-alaman namin, mula sa UK --
02:35
and built a test rig, and proved that, in fact,
58
143000
2000
bumuo ng test rig, at pinatunayan na
02:37
we could make a low pressure, non-toxic refrigerator.
59
145000
3000
maaring makagawa ng low pressure, non-toxic regfrigerator.
02:41
So, this is the way it works.
60
149000
1000
Ganito ang kanyang paggamit.
02:42
You put it on a cooking fire.
61
150000
1000
Ilalagay mo siya sa ibabaw ng pinaglutuang apoy.
02:43
Most people have cooking fires in the world,
62
151000
2000
Kahit sino sa mundo may pinaglulutuang apoy,
02:45
whether it's camel dung or wood.
63
153000
1000
yari man sa dumi ng kamelyo or sa kahoy.
02:47
It heats up for about 30 minutes, cools for an hour.
64
155000
3000
Paiinitan ito sa loob ng 30 minuto, at palalamigin ng isang oras.
02:50
Put it into a container
65
158000
2000
Ipapasok sa isang lagayan
02:53
and it will refrigerate for 24 hours.
66
161000
2000
at maari na itong gamiting refrigerator sa loob ng 24 oras.
02:55
It looks like this. This is the fifth prototype. It's not quite done.
67
163000
3000
Ganito ang itsura niya. Ito ang panlimang prototype. Hindi pa siya gaanong tapos.
02:59
Weighs about eight pounds, and this is the way it works.
68
167000
3000
Ito ay may bigat na 8 pounds, at ang paraan ng paggamit ay ganito.
03:02
You put it into a 15-liter vessel, about three gallons,
69
170000
3000
Ilalagay mo siya sa 15-litro na lalagyan, katumbas ng tatlong galon,
03:06
and it'll cool it down to just above freezing --
70
174000
2000
at ito ay lalamig malapit sa freezing point,
03:08
three degrees above freezing --
71
176000
1000
tatlong baitang na mas mataas sa freezing point,
03:10
for 24 hours in a 30 degree C environment. It's really cheap.
72
178000
3000
sa loob ng 24 oras at 30 degree Celsius. Ito ay napakamura.
03:13
We think we can build these in high volumes for about 25 dollars,
73
181000
3000
Sa tingin namin, puwedeng bumuo nito ng maramihan sa halagang 25 dolyar bawat isa,
03:16
in low volumes for about 40 dollars.
74
184000
2000
at kapag kaunti lang, aabot ng 40 dolyar.
03:18
And we think we can make refrigeration
75
186000
2000
At sa tingin namin magagawa nating
03:21
something that everybody can have.
76
189000
1000
abot-kaya ang refrigeration para sa lahat.
03:22
Thank you.
77
190000
1000
Salamat po!
03:23
(Applause)
