http://www.sendacow.org.uk Helen from Uganda shows how she is trialling using 1.5 litre plastic water bottles as a way of lighting her dark kitchen in the daytime. She uses the bottles, filled with water and a little bleach, grouped in 3s over her cooking areas in her dark mud kitchen with grass roof. Techniques like this can reduce eye strain and the need for electric lighting where electricity is too expensive or not available.

Comments:

• You could make larger "windows" by grouping more bottles together. You could also embed them into the mud walls when the house is being constructed, to let in more light from the sides. Attaching cloth flaps (from old clothes or feed sacks) over these windows would serve as shutters if you don't want as much light coming in.

• @ElveeKaye : Making "windows" embedded in the walls by grouping more bottles is a great idea. You could do colored water for "stained glass" windows! And as you suggested, if you want curtains, using feed sacks or old cloths - sewing together old t-shirts, for example - could make great curtains What a great idea. Can't wait to try this here in Guatemala.

How to Build a Solar Bottle Bulb 2.0 ( Updated English Version)

Mute sound (video has loud, distracting music) but good information:

Thanks to Marco Bieman from Bieman Production Haus Inc. Video Directing and Editing

1) Always scratch the sides of the bottle to create better grip to the sealant. The top part where the bottle meets the metal is the leak point in the build so use industrial strength sealant (epoxy or DOW Corning 791) on the top and bottom if possible.

2) Always put a protective cover over the bottle cap as the suns rays tend to make the original bottle cap brittle and a crack in the bottle cap will allow the water in the bottle to leak during evaporation.

3) Always RIVET the metal sheet holder on to the roof.

4) DON't USE THIN METAL ROOFING SHEETS. there will be no bite on the plastic bottle and the different expansion rates will cause leaks later on. Go for thicker roof sheet.

Comments:

• @CommentsSurvey vulcaseal is really sticky and is rubbery. when exposed to the sun it becomes hard like a rock. caulk or silicone sealant is good for preventing leaks but a stronger adhesive is recommended so the bottle wont slide off the flange.

• @CommentsSurvey its a pvc endcap. any endcap fitting for pipes will do.

Lights Made With Bottles & Water

Lights Made With Bottles & Water

Lights Made With Bottles & Water: Reusing 2-L bottles as solar bulbs is good for the environment in two ways: it cuts down on solid waste and electricity usage.

Solar bottle bulbs are lights made out of 2-L bottles that use no electricity and produce the same amount of light as a 50- to 60-watt incandescent bulb. These lights are used in developing countries where energy prices are high and median incomes are low. Nearly anyone can make these lights and install them in a workshop or other area where a hole can be cut in the ceiling to allow direct sunlight.

How They Are Made

Solar bottle bulbs are simple to construct. A 2-L bottle is filled with water and roughly two capfuls of bleach. A hole is cut in a square piece of corrugated metal and is placed around the bottle to prevent leakage through the roof and to help secure the bottle in place. A hole the same diameter as the bottle is then cut in the roof of the structure, and the bottle is inserted into the hole. The bottle cap is either covered in a protective substance or a plastic covering to protect it from sun damage.

How They Work

The lights work by refracting sunlight in a 360-degree arc around the room, which provides superior light to a window or skylight, only allowing light into a room in a direct beam. The bleach keeps the water clean and clear by preventing algae growth. The bottle lights should last around five years if left undisturbed.

Brazil

In 2002, Alfredo Moser, an engineer in Brazil, got the idea to use solar bottle bulbs in his workshop so that he could continue to work during the energy shortage. His neighbors, intrigued by the idea, soon started following suit, adding the bulbs to their homes in kitchens, bathrooms and living areas where electric light was prohibitively expensive and inefficient.

A Liter of Light

The MyShelter Foundation runs a program in the Philippines called Isang Litrong Liwanag: a Liter of Light. Based on a project developed by students at MIT under the Appropriate Technologies discipline, the project aims to bring sustainable, affordable lighting to the underprivileged rural communities in the country.

An Apple a Day: Solar Bottle Light

Some more excellent photos of the solar bottle bulb project, from the blog "An Apple a Day: Solar Bottle Light"

"The materials to create one include: (1) 1.5 or 2 liter soda PET bottle, (2) corrugated sheets; and (3) water+chlorox+salt." (Note: I'm not sure about the salt, but water+chlorox+plastic bottle is correct)

Solar Bottle Bulb Instructions (translated) = 50 watt bulb!

1. Watch both videos. These instructions are gleaned from the videos. Let us know how things work in real practice so the instructions can be updated.

PHILLIPINES (in English): http://www.youtube.com/watch?v=a9fpolCvM-8&feature=youtu.be

BRAZIL (in Spanish): http://www.youtube.com/watch?v=_zMAWztZ6TI

2. Start with squares of tin roofing material. Cut a hole smaller than the water bottle. It looks like about ½ inch or so smaller which are then cut into tabs which are bent upwards and the bottle is pushed up through the bottom of the square.

3. Fill the empty bottle with clean water and two capfuls of bleach. Close bottle with bottle cap. For faster filling, use a thin tube connected to the sink faucet to direct water into the bottle.

4. Caulk the bottle on both sides of the square piece of roofing material before installation, and let the caulk dry.

5. Mark the holes where you want the lights to be on the ceiling from inside house, and use a hole cutter to drill through the ceiling material and through the roof. Put two lines of bulbs down both sides of the room or as many lights as you want.

You can also cut the holes from the outside on top of the roof. Drill a pilot hole through the ceiling up through the roof, or use a chalk line and tape measure to transfer measurements from the ceiling onto the roof.

6. Cut the roof hole a bit larger than the bottle, so you can slide the bottle through. The square roofing plate will cover the hole later on. Use a hole saw, drill hole cutter attachment, or a metal cutting blade on a hand or electric saw.

7. Caulk the bottom of the square metal plate holding the empty bottle, and place the bottle in the hole. Press down to glue the square metal roofing plate into place.

8. Rivet or screw the plate down on all four corners.

9. Caulk all seams, rivets or screws, and coat the bottle cap with caulk to protect the cap from degradation from the sun’s rays.

10. Go inside, turn off any electric light in the room and see what happens!

11. Test roof for leaks after caulk is dry.

12. The Solar Water Bottle Light should last 2 to 5 years and give 50 watts of light.

1. Vea los videos. Estas instrucciones son recogidos de los videos. Háganos saber cómo funcionan las cosas en la práctica real de lo que las instrucciones se pueden actualizar.

2. Comience con cuadrados de material para techos de hojalata. Corte un agujero más pequeño que la botella de agua. Parece que alrededor de ½ pulgada o más pequeños que se cortan en las pestañas que están arriba se inclinó y la botella se empuja hacia arriba a través del fondo de la plaza.

3. Llena la botella vacía con agua limpia y dos tapones de lejía. Del frasco con la tapa de la botella. Para agilizar el llenado, la utilización de un tubo delgado conectado al grifo del fregadero de agua directamente en la botella.

4. Masilla de la botella en ambos lados de la pieza cuadrada de material de cubierta antes de la instalación, y dejar que la masilla seca.

5. Marque los agujeros en la que desea que las luces se en el techo de la casa de adentro, y el uso de un cortador de agujero para perforar el material del techo y por las nubes. Poner dos líneas de focos a ambos lados de la habitación o como las luces que quieras.

También puede cortar los agujeros desde el exterior en la parte superior del techo. Perfore un agujero piloto a través del techo a través del techo, o utilizar una línea de tiza y una cinta métrica para transferir las mediciones del techo en el techo.

6. Corte el agujero del techo un poco más grande que la botella, por lo que se puede deslizar a través de la botella. La placa de techo cuadrados cubrirá el agujero en el futuro. Use una sierra circular, taladro de fijación agujero de corte, o una hoja cortante metal en la mano o sierra eléctrica.

7. Masilla de la parte inferior de la placa metálica cuadrada que tiene la botella vacía, y coloque la botella en el agujero. Presione hacia abajo para pegar la placa de metal para techos cuadrados en su lugar.

8. Remaches o tornillos del plato en las cuatro esquinas.

9. Selle todas las costuras, remaches o tornillos, y la capa de la tapa del frasco con material de calafateo para proteger la tapa de la degradación de los rayos del sol.

10. Entrar, apaga cualquier luz eléctrica en la habitación y ver qué pasa!

11. Techo de la prueba de fugas después de masilla se seca.

12. La luz de la botella de agua solar debe durar de 2 a 5 años y dar 50 vatios de luz.



I also lived in a very charming house that had a 24" or 36" strip of lucite plexiglass all around two sides of the house up at the roof line. It was wonderful and let in so much light I never had to use lights anywhere during the day. Plus no leaking since it was under the roof line, not in the roof.

Good luck and please, keep us updated!

Lighting up a million homes through solar power

In: Technology
15 Feb 2011

Dear readers,

Let’s talk about something light and constructive, shall we? It is the love month after all and we are reminded to share it unconditionally. I already actually published this post a couple of days ago but I still needed more info on the project.

The Solar Bottle Bulb Project has an ambitious goal – to light up 1 million homes by 2012. According to statistics from the National Electrification Commission in 2009, 3 million households still remain powerless outside Metro Manila. The team started installing the solar bulbs in a couple of homes in Pasay City with a liter-sized soda bottle. I was trying to work out in my mind how a solar bulb would work without using some complicated technology. Here’s a demo video:

My Shelter Foundation, spearheaded by Illac Diaz, is in the process of unfolding another groundbreaking campaign to bring at least 55watts of light to thousands of households in the shanty areas across the country. Imagine – just using a 1.5 soda bottle, some chlorine and a rubber sealant.

Okay, this is how it works. The solar bottle bulb was designed and developed by students from the Massachusetts Institute of Technology (MIT); a device based on the principles of Appropriate Technologies – a concept that provides simple and easily replicable technologies that address basic needs in developing communities. The water and other chemicals allows full spectrum of light to come into the house. We’re not the first one to try this. Brazil and Mexico are using the same technology as well.

Instructions I read on one of the comments on their Facebook page:

“fill a 1.5 liter clear soft drink bottle with purified water as tap water will eventually produce moss, then add 3 tablespoons of liquid bleach and tightly seal the cap.”

We went to homes in Pasay last week during lunch time where the solar bottle bulbs were first installed. Instead of using electricity during the day, the residents now have an option to use the solar bulbs and lessen their electric bills. It’s amazing how this simple of a technology can harness the power of the sun in the most efficient way to light up hundreds of homes.

This doesn’t just save electricity, it also prevents fire as well, especially in shanties that use candles even in the daytime. The scenario – families desperately try to source electricity through illegal or unsafe means – usually resulting into disaster. According to the Bureau of Fire Protection (BFP), accidents which result into fires often involve faulty electrical connections. Not just that, it also lessens garbage as well!

I cannot begin to imagine how the residents would live in their houses without the solar bulbs they’re using now. The absence of light, really, is daunting.

Right now, My Shelter Foundation just has one prototype. They’re continually experimenting with different materials to spread the technology. I think the not-so-poor households can benefit from another prototype, but, of course, installing these solar bulbs in communities that need it is the first order of business. Seriously, this can change the face of urban living.

The foundation is exploring partnerships with both private and public entities to implement this project nationwide. As an individual, you can start helping by donating your PET bottles. PET Bottle bins can be deposited at the back of the Insular Life buildings in both Makati and Alabang.

“Light is an important part of our daily life, and access to light is a right of everyone here in the country,” says Diaz. “Through this project, we aim to provide the whole country with sustainable light energy – and bridge the gap between social classes. With the Solar Bottle Bulb project, a brighter Philippines is going to become a reality,” ends Diaz.

Illac Diaz is also working on Design Against the Elements (DATE) and the Bottle School Run.

Read more about the project at http://www.aliteroflight.org/ or add them on twitter: aliteroflight. Please support this cause by either reposting this article and spreading the word. I’ll post another update once I get word from the organizers.

Let’s make a brighter Philippines!

TTFN,
Faith
