Solar Bottle Bulb Lights Up Philippines

Isang Litrong Liwanag (A Liter of Light), is a sustainable lighting project which aims to bring the eco-friendly Solar Bottle Bulb to disprivileged communities in Philippines. Designed and developed by students from the Massachusetts Institute of Technology (MIT), the Solar Bottle Bulb is based on the principles of Appropriate Technologies – a concept that provides simple and easily replicable technologies that address basic needs in developing communities.

The bottle bulb can be created using a 1 liter soda bottle that is filled with a solution of purified water and bleach. It only costs $2-3 to make, and the chlorine and bleach keep molds from developing so the solution can last up to five years. Although the water needs to be replaced every five years and the bulb will not work at night, the advantages are still overwhelming for communities that are deprived of daylight.
