Come to think of it, a light bulb that does not require electricity to produce light. This is just perfect for our fellow Filipinos who live below the poverty line and those who do not have electricity line connected to their houses.
It is given that when a family cannot sustain the basic necessity to live (food, shelter and clothing) then, why would they care for paying their electricity bill? People would just prioritize how they can fill their stomach – and it is a trend that they usually choose instant noodles and rice. Very sad, indeed.
Once there were some people in Brazil who tested this innovation which was researched and adopted by the MIT students. And now, they’re bringing the simple technology here in the Philippines.
Isang Litrong Liwanag Movement or A Litre of Light has helped residents of Laguna and Metro Manila including those in Baseco compound to install plastic soda bottles filled with mineral water and an ample amount of bleach to light up their dark homes.
The technology is pretty simple. When you pinch a hole on your roof, the light as its normal behavior, will come down directly to a specific spot on your floor as it travels in one direction. The water inside the bottle breaks this line and scatters them. When you go back to your elementary notes, this is called refraction. So, it gives a glowing effect from the natural source of energy – cheap and eco-friendly.
Now tell me, why bleach? The bleach and the clean mineral water preserves the life of the light bottle and prevents it from algae and fungi development up to five years.
These bottles are placed on a roof scrap metal and sealed with a sealant, placed within the radius of the hole on your roof. Mang Jose installs these for a minimal amount of 200 pesos. Thats less than US$ 5 for one bottle.
Given that you will not get the light you need during dusk, night or rainy season, it still provides free light source especially during summer season.
