Good morning!
These days I've been spending here, have taught me a great deal.
In fact, I think I came here more to learn than to teach or talk.
We actually come from a big city, from Rio de Janeiro,
and I don't have direct contact w ith all we have seen here,
all that Edgar, the last speaker, showed us.
It's been awesome for me, it's been really cool.
We are here at TEDx Amazon,
to talk about the "Efficient Lighting Project".
We need light, we need to see better,
and society has preached that
in order to see better we need super-efficient light bulbs
or more and stronger ones.
Actually, we don't need any of that.
We can utilize other means to improve lighting.
As a result, we will change our level of awareness.
Changing the level of awareness is
going from an incandescent light bulb, which is a hot bulb,
to a cold one.
Is this bulb more efficient? Does it save more?
Yes, but we can do more.
We can achieve the best results with the lowest consumption,
with this more efficient lamp.
I stopped to think when I found out
about this micro-technology,
"Why didn’t I think of this before?"
It's so simple.
I have a light bulb at home,
and I keep looking for others to improve the lighting conditions,
Why didn’t I think of this before?
I kept asking myself this.
It really bothered me.
This technology consists of
anodized aluminum foil that reflects light.
As if it were a mirror.
However, if it were a mirror, this is what it would look like:
If there were a glass, it would only mirror the glass.
If there were a light bulb, it would only mirror the bulb.
When I place this foil in the shape of a parabola,
I amplify the image and, therefore, increase the light.
I can produce more light
with the lowest resource consumption possible.
A long time ago, we used to have lamps that didn’t direct the light anywhere.
Then the idea of a reflector came about.
I can use this surface to direct light.
That's how we started, and we can improve.
Today, how do we use it?
On the slide, you can see two incandescent light bulbs.
I also brought this straight fluorescent bulb.
The traditional way to use it
is to put two of them together in this model
in order to obtain good luminosity.
What we can do now is to use only one bulb in this model
with a reflective parabola-shaped foil
providing us the same result
or, even better,
up to 180% more light
than the two lamps without the reflective foil.
We tested it.
In order to do the test, we need a light meter to measure the light.
This way you can check how much light is generated.
This is what we did in a company, a large company I work for, Oi.
We implemented this project in our building.
We took care of the buildings,
and in all our offices we installed lamps such as this one we have here,
lamps with these two fluorescent tubes.
I had 262 lux, the right amount of light on a desk with two flourescent bulbs.
When I removed one of them and installed the foil, we reached 470 lux.
Therefore, it was about a 100% increase in light.
We also installed it in the parking garage where we had 51 lux with two bulbs of 40.
Now we have 140 lux.
There are more advantages. What are they?
Up to 50% in energy savings.
We actually save more,
because I am removing one bulb,
50% less in the electric bill.
owever, the bulb I removed will be reused,
the reactor I removed will also be reused.
I can reuse the product much more,
cut costs and achieve the lighting conditions that I need.
I can double the light,
reduce the temperature in the environment,
and it's excellent for areas with air conditioning,
and the system maintenance becomes less frequent.
There were around 1700 lamps
with two bulbs in each one.
Today there are 1735 bulbs.
It's more ecofriendly, there is less waste and power consumption,
and it emphasizes colors.
We can reuse the existing lamps and bulbs.
There are advantages, but there is one disadvantage.
What would it be?
When I install the foil, it creates a focus point.
When I put the lamp here, it creates
a focus point for this environment.
When I remove the foil, light spreads a little more.
This is the only disadvantage, which can be easily solved.
All we have to do is to better distribute the lamps
in order to use light the way we need it.
What was the project's financial feasibility?
Before we implemented the project,
we used to spend R$335,000 on lighting,
considering that the 1735 lamps were on 24h a day during the whole year.
The cost was R$0.35 per KW
Removing one bulb from each lamp, I save 50%.
And this savings is only by removing one bulb from each lamp,
not to mention how much I save by not having to make any other purchase.
Now we spend R$ 167,000 a year.
This is equivalent to a "payback" of 9 months.
Therefore, I paid off this investment in 9 months
and had an implementation cost of R$ 121,000.
What does that mean?
If I have a 32w bulb,
which is slightly more than this one, and it is on 24h a day,
it is equivalent to 26 full 2L water bottles,
and I am constantly wasting this water.
This means that 1735 lamps, on 24h a day,
represent a consumption of 45,100 2L water bottles;
that is, 90,200L of water being wasted
if these bulbs are on.
So if I have this behavior and take this simple action
of removing one bulb and reusing it to do better,
I'm not only enjoying a 50% gain,
but I am also enjoying an enormous gain in water savings.
We won't be wasting water as much as we do today
as we can see here in the Amazon.
I have always seen the Amazon on TV and have always been touched,
but not as much as I am now by being here and seeing what we've got today.
This makes me want to do more every day,
even if it's just a simple attitude change.
We can do it and have great results.
Then we will have much more light
for much less cost.
We will have more light
without having to spend even an extra penny on power.
Yesterday I was surprised when I read the Sorrir magazine
and found the piece "Work to live a better life".
I was honored.
It talks about the experience of people who created things
we couldn't even imagine, and then they would think,
"How simple! Why didn't think of that?"
Then this sentence called my attention,
"If there is an obstacle in your path, you can either lament or overcome it."
The first choice is easier, but it leads nowhere.
The second allows us to not only solve a problem
but also to do something for humankind."
Even this simple change in attitude presents obstacles to its achievement.
We'll have to struggle to overcome these obstacles
and contribute to the development of society.
Thank you.
