The way it works is very simple, which is only refract light of the sun or moon (only when the moon is bright enough) that goes through the hole in the roof, then spread throughout the room. (The result will be very different if we only use glass tile or make a hole in the roof without installing bottle bulb)
Bahan-bahan yang digunakan:
Soda bottles of 1.5 liters
The sheets corrugated or flat (± 30 x 30 cm)
Whitening Fluid Clothes 2 bottle caps (to prevent the growth of moss in water bottle)
Rubber Sealant (leak-proof coating for roofs)
Clear water (preferably of bottled mineral water, to prevent the water becomes cloudy after installing some time)
Ways of making:
1. Potong lembaran seng menjadi ukuran 30 x 30 cm
2. Draw a circle about the size of the diameter of the central part of the soda bottle, and inside the circle, drawing a smaller circle with a distance of about 1cm, as in the picture
3. Cut the inner circles (small circle line) and create pieces like the picture on the remaining portion of the outer loop for attaching a bottle
4. Rub the middle of a soda bottle with sandpaper, so that part was not slippery and strong bonding when placed on a sheet of zinc
5. Enter the half of the bottle into the hole on the sheet of zinc and paste with rubber sealant (leak-proof coating) Ensure implementation evenly and fairly. then wait until really dry
6. Once the rubber sealant is dry, fill the bottle with clear water, then add approximately 2 fluid bottle cap household bleach (to prevent the growth of moss on the bottle)
Then the lid back on the bottle with a lid, and is ready to install BULB SOLAR BOTTLE
How to install:
1. Make a hole diameter of a bottle on the roof is not obstructed in any
2. Attach your BULB SOLAR BOTTLE in holes that have been made on the roof
3. Create four holes with a drill-through on each side end BOTTLE SOLAR BULB zinc, whose function is to put a nail rivet (rivets). Then attach the rivet nail that BOTTLE SOLAR BULB not easy to shift.
4. Close any open slot with rubber sealant so that the roof does not leak
Congratulations !! BOTTLE SOLAR BULB you have finished
The result:
This lamp initiative known as "One Liter of Light", aimed at providing sustainable energy to the poor, an idea initiated by the Massachusetts Institute of Technology student.
10,000 bottles of lights have been installed in Manila and nearby provinces of Laguna. The project was carried out by local governments, and private partners who are dedicated to low-income communities.
For residents of the disadvantaged, this means it can save money for lighting, and there is more money to the daily diet.
