Light from a soda bottle

There is a video article on my blog at, about a project by Filipino “eco-entrepreneur” Illiac Diaz.

He founded My Shelter Foundation and works with Isang Litrong Liwanag (A Liter of Light) “a sustainable lighting project which aims to bring the eco-friendly Solar Bottle Bulb to disprivileged communities nationwide.

Originally 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”.

What a great way to recycle soda bottles!

These bottles admit clear light to a dark home using only sunshine and purified water (with a little bleach added to discourage algae growth), for up to 5 years.

The lighting device can be installed in less than 1 hour, improving standards of living in poor, densely populated areas, where safe lighting is an issue.

Kudos to Illiac Diaz and this project!
