A community in Laguna finds an ingenious way to solve their electric bill problem through solar-powered light bulbs made from an empty plastic soda bottle, water, and bleach.

Here are videos I got from youtube:

What they do is create a hole on the roof and insert the bottle filled with water and bleach, and presto, instant lighting. It’s really a very clever and cheap way to have an alternative roof lighting system in your homes (which usually cost a lot of custom challenge coins down to thousands).

This is just one among the many communities assisted through the very noble project, Isang Litrong Liwanag, being initiated by the handsome Mr. Illac Diaz (and the Rotary Club). It aims to bring “light” to communities nationwide through the Solar Bottle Bulb developed by students from the Massachusetts Institute of Technology (MIT).

Here’s an info about the Project I lifted from their facebook account:

“A Liter of Light is a program inspired by many innovations from around the world. Many cultures have used glass bottles to allow lighting through the roof, and Alfredo Moser from Brazil began pioneering methods of experimenting with plastic bottles. There has been modifications to the Philippine model, but what must be emphasized the amount of people whose lives are being affected by this innovation.”

I’ve also decided to post this on facebook where a friend of mine suggested that perhaps, and to the best interest of more people, maybe someone could invent a lunar bulb so houses could still be lit up even at night. Here’s a bit of that talk:

My friend: Illac sent me the mechanics, it works when the sun is up. The logic behind it being “solar” but during night time, I wonder how it would work..sana he comes up with lunar powered light too.

Me: You’re right, bff Monette Atienza-Santos… so i guess that’s where solar panels come in… to trap the energy para even if at night, may ilaw pa rin. I believe this solar bottle bulb is a “mini” and cheap version of the natural light roof system being used in a lot of buildings now.

Anyway, if you want to help the group reach the goal of lighting a million homes by 2012, or simply have inquiries, you may email them at info@aliteroflight.org.
