Solar Bottle Bulb

July 23rd, 2011 Posted by environment 6 thoughts on “Solar Bottle Bulb”

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.

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.

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 is a video with founder, Illac Diaz:

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.”

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
