Alfredo Moser: Bottle light inventor proud to be poor
BBC News Magazine, BBC World Service, Uberaba, Brazil ^ | 12 August 2013 | By Gibby Zobel

Posted on 09/05/2013 9:11:08 AM PDT by PrayAndVoteConservesInLibsOut

Alfredo Moser's invention is lighting up the world. In 2002, the Brazilian mechanic had a light-bulb moment and came up with a way of illuminating his house during the day without electricity - using nothing more than plastic bottles filled with water and a tiny bit of bleach.

In the last two years his innovation has spread throughout the world. It is expected to be in one million homes by early next year.

So how does it work? Simple refraction of sunlight, explains Moser, as he fills an empty two-litre plastic bottle.

"Add two capfuls of bleach to protect the water so it doesn't turn green [with algae]. The cleaner the bottle, the better," he adds.

Wrapping his face in a cloth he makes a hole in a roof tile with a drill. Then, from the bottom upwards, he pushes the bottle into the newly-made hole.

"You fix the bottle in with polyester resin. Even when it rains, the roof never leaks - not one drop."

The lamps work best with a black cap - a film case can also be used "An engineer came and measured the light," he says. "It depends on how strong the sun is but it's more or less 40 to 60 watts," he says.

Look at how something so simple is changing lives. This is awesome! There is more at the link..and even a great little video about it there. Here is a little bit more from this article:

Diaz says you can find Moser lamps in some remote island communities. "They say, 'Well, we just saw it from our neighbour and it looked like a good idea.'" People in poor areas are also able to grow food on small hydroponic farms, using the light provided by the bottle lamps, he says.

Overall, Diaz estimates, one million people will have benefited from the lamps by the start of next year.

"Alfredo Moser has changed the lives of a tremendous number of people, I think forever," he says.

"Whether or not he gets the Nobel Prize, we want him to know that there are a great number of people who admire what he is doing."

Did Moser himself imagine that his invention would have such an impact?

"I'd have never imagined it, No," says Moser, shaking with emotion.

"It gives you goose-bumps to think about it."

Light to work in Bangladesh

Most homes and businesses in the slums of Dhaka have no power and no windows, so 80-90% of them hook up to electricity lines illegally - and fall back on candles or kerosene lamps during regular blackouts.

A voluntary organisation called Change began distributing the bottle light, or botul bati, earlier this year. It's helped hundreds of people - including sari makers and rickshaw repairers - whose livelihoods depend on having sufficient light.

There were teething problems. "Some people said they felt poorer after installing a bottle light," says Change founder Sajid Iqbal. The group counters this by stressing that each one helps tackle climate change.

Unlike some other charities, Change charges a small amount for the lights - roughly the price of 2-3kg of rice. "If you give the light for nothing, people don't maintain them," Iqbal says. "They don't understand their value."

More than a sky light, more like a deck prism. Much better illumination than a mere hole in the roof.

It’s not a BFD to the likes of you and me who have ready access to cheap and reliable electricity, but for most of the world it really is a BFD.

Wait, where’s the government in this? Mr. Moser needs their help.

What an awesome idea. And the part about a small charge is also critical. Teaching a man to fish does not mean giving him an unlimited supply of line and hooks.

Good for him. His idea is very much like the deck prisms that were used on the sailing ships of old.

That was my question too. Also, how well does this work in the winter when they freeze? How well does it insulate? And I doubt they last very long before leaking starts considering the degradation of plastic from UV and the constant expansion and contraction associated with the warming and cooling.

Also, what if you don't have cathedral ceilings for the "water filled skylight"? Who thought this was a good idea again?

Sailing ships had glass prisms in the deck to distribute light to lower decks.

That this is made out of what is essentially garbage is new, but it replaced ‘going outside’ for most users.

Expect more insanity as less sociable poor people stay in their homes rather than being in a social situation getting feedback.

What are windows for? AND You can probably spread around the light a bit more, but you can't get more light in through the hole than hits the hole to start with (First law) In fact you'll get LESS light than hits the hole (Second law) Making a hole i your roof isn't making a light bulb it's just making a hole in your roof. (You can't rollerskate in a buffalo herd either) I reiterate BFD.

Seriously low chance of freezing in Brazil, along the equator. The temperature is quite constant, like in Hawaii, limiting the expansion and contraction issue. And less tramatic than having to bury your kid when your jerry-rigged stolen electricity short-circuits.

I think it is a great idea, especially good for people in 3rd World countries. As for the environmentalists, I would love to see them drilling holes in THEIR roofs to install the soda bottles while dispensing with all of their regular lighting. But I am not holding my breathe. This is just another thing for the masses, but not for the elites. Along the same lines as Sheryl Crow pronouncing that we should only be allowed one square of toilet tissue at a time to meet our needs while using the toilet.

Fair enough. My perspective was the practicality of me being able to use this technology. With respect to poor Brazilians, this is brilliant.

Thank you for forcing me to reconsider the context of the story.

Actually, If I understand it right, it is refracted light, which takes the light from inside the bottle and then illuminates the surrounding area as would a 40 watt bulb. So at night unless the moon is bright, there probably still is darkness. ZZZZZZZZZZZZZZZZ

The thing is you have extended the 'light-catching area' above the roof. So you have increased the amount of light coming through the roof at all times of day except noon.

My brother bought a condo that has 2 solartubes installed. One is in the kitchen right over the prep area and the other is over the entryway. It is amazing how much light they put out. We haven’t checked how but they also put out light at night, like a very bright nightlight.
They actually are super cool but I checked and they are kind of expensive.

Now this is what my old Engineering Professor would call, “elegant”. Very simple, yet very effective.

Obviously not for houses like ours, but a tremendous advance for third world folks who can’t get/afford electricity but need light during the day.

(P.S. I’m often a pretty cynical guy. If I shake MY head at your cynicism, you have a problem, in my opinion. This guy is not a politician, he’s not trying to be famous or rich, and he’s not claiming he’s found the solution to the world’s energy problems. He’s also not trying to sell you on it. HE’S JUST OFFERING HELP TO PEOPLE WHO NEED IT. So all you “so what” guys out there, please just take a deep breath, and realize, not everything deserves to be reviled.)

Also, how well does this work in the winter when they freeze? How well does it insulate?

.........Probably not an issue in the slums of India, African huts or tin shacks of Haiti.

And I doubt they last very long before leaking starts

.........Their shacks probably already leak.

Also, what if you don’t have cathedral ceilings for the “water filled skylight”?

........Most shacks in these areas do have “cathedral ceilings”.

Probably not the best idea for 90% of Americans, although I just might try this out in my shed, which I never did get around to wiring for electric.

Thanks for this info. Also, to those interested, the article explains it this way:

“Refraction is the bending of light, which is caused by a change in its speed.
The speed of light is determined by the density of the substance through which it passes.
So refraction occurs when light passes from one substance to another with a different density - eg from air to water
In the case of the “Moser lamp”, sunlight is bent by the bottle of water and spread around the room.

Thanks for posting everyone.

The big problem I have seen with these ‘lights’ is the photo-reactive property of plastic. It breaks down and falls apart at various rates, depending on the intensity of the sun. In the tropics, I would give it a year. then you work to replace them or you have gaping holes in the roof to let the rain rot the wooden structure....Glass bottles would be better than plastic.

This sounds to me like it work a lot like those little, round skylights that they sell. A lot more light enters the room than just the diameter of the hole because there are reflectors inside the shaft that enhance the light.
