0:00:17.042,0:00:18.291
Good morning!

0:00:19.392,0:00:24.541
These days I've been spending here,[br]have taught me a great deal.

0:00:24.542,0:00:31.333
In fact, I think I came here[br]more to learn than to teach or talk.

0:00:31.334,0:00:35.666
We actually come from a big city,[br]from Rio de Janeiro,

0:00:35.667,0:00:40.500
and I don't have direct contact w[br]ith all we have seen here,

0:00:40.501,0:00:46.043
all that Edgar,[br]the last speaker, showed us.

0:00:46.083,0:00:50.667
It's been awesome for me,[br]it's been really cool.

0:00:50.667,0:00:54.208
We are here at TEDx Amazon,

0:00:54.209,0:00:58.583
to talk about[br]the "Efficient Lighting Project".

0:00:58.584,0:01:02.999
We need light,[br]we need to see better,

0:01:03.000,0:01:05.123
and society has preached that

0:01:05.125,0:01:10.789
in order to see better[br]we need super-efficient light bulbs

0:01:10.790,0:01:14.788
or more and stronger ones.

0:01:14.792,0:01:17.416
Actually, we don't need any of that.

0:01:17.417,0:01:22.208
We can utilize other means[br]to improve lighting.

0:01:22.209,0:01:25.890
As a result, we will change[br]our level of awareness.

0:01:25.891,0:01:27.518
Changing the level of awareness is

0:01:27.519,0:01:30.543
going from an incandescent light bulb,[br]which is a hot bulb,

0:01:30.544,0:01:32.208
to a cold one.

0:01:32.209,0:01:34.960
Is this bulb more efficient?[br]Does it save more?

0:01:34.961,0:01:37.741
Yes, but we can do more.

0:01:37.751,0:01:43.362
We can achieve the best results[br]with the lowest consumption,

0:01:43.363,0:01:45.830
with this more efficient lamp.

0:01:45.834,0:01:50.498
I stopped to think when I found out

0:01:50.499,0:01:54.615
about this micro-technology,

0:01:54.616,0:01:57.174
"Why didn’t I think of this before?"

0:01:57.175,0:01:59.444
It's so simple.

0:01:59.445,0:02:01.374
I have a light bulb at home,

0:02:01.375,0:02:05.375
and I keep looking for others[br]to improve the lighting conditions,

0:02:05.403,0:02:07.030
Why didn’t I think of this before?

0:02:07.031,0:02:09.999
I kept asking myself this.

0:02:10.000,0:02:12.249
It really bothered me.

0:02:12.250,0:02:15.666
This technology consists of

0:02:15.667,0:02:21.626
anodized aluminum foil[br]that reflects light.

0:02:21.647,0:02:24.041
As if it were a mirror.

0:02:24.042,0:02:29.918
However, if it were a mirror,[br]this is what it would look like:

0:02:29.918,0:02:33.710
If there were a glass,[br]it would only mirror the glass.

0:02:33.751,0:02:37.252
If there were a light bulb,[br]it would only mirror the bulb.

0:02:37.253,0:02:41.124
When I place this foil[br]in the shape of a parabola,

0:02:41.125,0:02:45.626
I amplify the image[br]and, therefore, increase the light.

0:02:45.626,0:02:49.249
I can produce more light

0:02:49.250,0:02:53.666
with the lowest resource[br]consumption possible.

0:02:53.667,0:02:57.352
A long time ago, we used to have lamps[br]that didn’t direct the light anywhere.

0:02:57.353,0:03:00.354
Then the idea of a reflector came about.

0:03:00.355,0:03:04.709
I can use this surface to direct light.

0:03:04.710,0:03:07.308
That's how we started, and we can improve.

0:03:07.309,0:03:09.113
Today, how do we use it?

0:03:09.125,0:03:15.334
On the slide, you can see[br]two incandescent light bulbs.

0:03:15.334,0:03:20.666
I also brought[br]this straight fluorescent bulb.

0:03:20.667,0:03:23.500
The traditional way to use it

0:03:23.501,0:03:26.168
is to put two of them[br]together in this model

0:03:26.205,0:03:27.880
in order to obtain good luminosity.

0:03:27.881,0:03:33.543
What we can do now is[br]to use only one bulb in this model

0:03:33.560,0:03:37.291
with a reflective parabola-shaped foil

0:03:37.292,0:03:42.791
providing us the same result

0:03:42.792,0:03:46.531
or, even better,

0:03:46.532,0:03:49.750
up to 180% more light

0:03:49.751,0:03:55.834
than the two lamps[br]without the reflective foil.

0:03:55.835,0:03:57.333
We tested it.

0:03:57.334,0:04:01.459
In order to do the test, we need[br]a light meter to measure the light.

0:04:01.501,0:04:04.584
This way you can check[br]how much light is generated.

0:04:04.585,0:04:11.166
This is what we did in a company,[br]a large company I work for, Oi.

0:04:11.167,0:04:15.374
We implemented[br]this project in our building.

0:04:15.375,0:04:17.500
We took care of the buildings,

0:04:17.500,0:04:22.793
and in all our offices we installed[br]lamps such as this one we have here,

0:04:22.795,0:04:25.821
lamps with these two fluorescent tubes.

0:04:25.834,0:04:31.458
I had 262 lux, the right amount of light[br]on a desk with two flourescent bulbs.

0:04:31.459,0:04:36.958
When I removed one of them and installed[br]the foil, we reached 470 lux.

0:04:36.959,0:04:42.334
Therefore, it was[br]about a 100% increase in light.

0:04:42.375,0:04:47.876
We also installed it in the parking garage[br]where we had 51 lux with two bulbs of 40.

0:04:47.884,0:04:49.458
Now we have 140 lux.

0:04:49.459,0:04:52.709
There are more advantages. What are they?

0:04:52.751,0:04:55.917
Up to 50% in energy savings.

0:04:55.918,0:04:59.036
We actually save more,

0:04:59.037,0:05:03.711
because I am removing one bulb,

0:05:03.751,0:05:06.037
50% less in the electric bill.

0:05:06.038,0:05:10.958
owever, the bulb I removed will be reused,

0:05:10.959,0:05:13.001
the reactor I removed will also be reused.

0:05:13.002,0:05:15.584
I can reuse the product much more,

0:05:15.584,0:05:20.460
cut costs and achieve[br]the lighting conditions that I need.

0:05:20.465,0:05:23.234
I can double the light,

0:05:23.235,0:05:25.958
reduce the temperature in the environment,

0:05:25.959,0:05:28.399
and it's excellent[br]for areas with air conditioning,

0:05:28.400,0:05:30.751
and the system maintenance[br]becomes less frequent.

0:05:30.752,0:05:34.875
There were around 1700 lamps

0:05:34.876,0:05:38.038
with two bulbs in each one.

0:05:38.042,0:05:39.334
Today there are 1735 bulbs.

0:05:39.375,0:05:43.959
It's more ecofriendly, there is[br]less waste and power consumption,

0:05:43.959,0:05:45.334
and it emphasizes colors.

0:05:45.375,0:05:48.542
We can reuse the existing lamps and bulbs.

0:05:48.542,0:05:53.667
There are advantages,[br]but there is one disadvantage.

0:05:53.690,0:05:54.958
What would it be?

0:05:54.959,0:05:57.918
When I install the foil,[br]it creates a focus point.

0:05:57.919,0:06:01.460
When I put the lamp here, it creates

0:06:01.463,0:06:05.197
a focus point for this environment.

0:06:05.209,0:06:09.416
When I remove the foil,[br]light spreads a little more.

0:06:09.417,0:06:14.459
This is the only disadvantage,[br]which can be easily solved.

0:06:14.459,0:06:17.459
All we have to do[br]is to better distribute the lamps

0:06:17.460,0:06:19.808
in order to use light the way we need it.

0:06:19.809,0:06:23.124
What was[br]the project's financial feasibility?

0:06:23.125,0:06:24.917
Before we implemented the project,

0:06:24.918,0:06:31.291
we used to spend[br]R$335,000 on lighting,

0:06:31.292,0:06:38.289
considering that the 1735 lamps[br]were on 24h a day during the whole year.

0:06:38.290,0:06:41.999
The cost was R$0.35 per KW

0:06:42.000,0:06:45.042
Removing one bulb[br]from each lamp, I save 50%.

0:06:45.042,0:06:48.001
And this savings is only[br]by removing one bulb from each lamp,

0:06:48.002,0:06:51.585
not to mention how much I save[br]by not having to make any other purchase.

0:06:51.624,0:06:55.541
Now we spend R$ 167,000 a year.

0:06:55.542,0:06:59.416
This is equivalent[br]to a "payback" of 9 months.

0:06:59.417,0:07:01.876
Therefore, I paid off[br]this investment in 9 months

0:07:01.876,0:07:08.668
and had an implementation cost[br]of R$ 121,000.

0:07:08.672,0:07:09.936
What does that mean?

0:07:09.937,0:07:13.708
If I have a 32w bulb,

0:07:13.709,0:07:17.168
which is slightly more than this one,[br]and it is on 24h a day,

0:07:17.169,0:07:21.941
it is equivalent[br]to 26 full 2L water bottles,

0:07:21.942,0:07:25.528
and I am constantly wasting this water.

0:07:25.542,0:07:30.541
This means that 1735 lamps, on 24h a day,

0:07:30.542,0:07:35.307
represent a consumption[br]of 45,100 2L water bottles;

0:07:35.308,0:07:41.123
that is, 90,200L of water being wasted

0:07:41.124,0:07:43.746
if these bulbs are on.

0:07:43.751,0:07:48.458
So if I have this behavior[br]and take this simple action

0:07:48.459,0:07:54.472
of removing one bulb[br]and reusing it to do better,

0:07:54.473,0:07:57.708
I'm not only enjoying a 50% gain,

0:07:57.709,0:08:00.437
but I am also enjoying[br]an enormous gain in water savings.

0:08:00.438,0:08:02.751
We won't be wasting water[br]as much as we do today

0:08:02.779,0:08:05.500
as we can see here in the Amazon.

0:08:05.501,0:08:10.291
I have always seen the Amazon on TV[br]and have always been touched,

0:08:10.292,0:08:14.084
but not as much as I am now by being here[br]and seeing what we've got today.

0:08:14.085,0:08:18.999
This makes me want to do more every day,

0:08:19.000,0:08:21.058
even if it's[br]just a simple attitude change.

0:08:21.059,0:08:24.166
We can do it and have great results.

0:08:24.167,0:08:30.027
Then we will have much more light

0:08:30.028,0:08:31.382
for much less cost.

0:08:31.383,0:08:34.482
We will have more light

0:08:34.501,0:08:38.416
without having to spend[br]even an extra penny on power.

0:08:38.417,0:08:43.832
Yesterday I was surprised[br]when I read the Sorrir magazine

0:08:43.833,0:08:48.485
and found the piece[br]"Work to live a better life".

0:08:48.486,0:08:49.958
I was honored.

0:08:49.959,0:08:55.208
It talks about the experience[br]of people who created things

0:08:55.209,0:08:58.418
we couldn't even imagine,[br]and then they would think,

0:08:58.419,0:09:00.615
"How simple! Why didn't think of that?"

0:09:00.626,0:09:05.958
Then this sentence called my attention,

0:09:05.959,0:09:10.626
"If there is an obstacle in your path,[br]you can either lament or overcome it."

0:09:10.627,0:09:13.668
The first choice is easier,[br]but it leads nowhere.

0:09:13.669,0:09:17.042
The second allows us[br]to not only solve a problem

0:09:17.083,0:09:19.834
but also to do something for humankind."

0:09:19.834,0:09:25.625
Even this simple change in attitude[br]presents obstacles to its achievement.

0:09:25.626,0:09:28.458
We'll have to struggle[br]to overcome these obstacles

0:09:28.459,0:09:30.626
and contribute[br]to the development of society.

0:09:30.627,0:09:32.614
Thank you.
