Thank you Marites for this:

This is the official website of Isang Litrong Liwanag, the group initiating this project here in the Philippines. This is a project of MyShelter Foundation of Illac Diaz.

Thank you for this blog!
One word: Genius.

Q: What’s full of empty calories, packed in disposable plastic, saves energy, helps Earth’s ecology, and improves the lives of the world’s poor?

A. Coca-Cola in 1.5 liter plastic bottles.

It’s the bottles, not the sugary stuff inside them. Fill the empty plastic container with water and a touch of bleach (to suppress growth of clouding algae). Punch a hole in the corrugated steel roof of your shanty, make a secure metal collar for the bottle and use it to fix the container halfway-in. halfway-out of the house. Seal with a bit of caulk to make it water-tight. The sun will now fill the dark interior of your dwelling with the light of a 55-watt lightbulb, without electricity.

This simple action, installation of a cost-effective “solar lightbulb” or skylight, could vastly improve the lives of billions of poor people in sun-swept favelas, shantytowns, and bidonvilles and scattered rural dwellings around the globe. Watch a coke-bottle lightbulb being made in the Philippines. You don’t have to understand the language to appreciate the significance of the change in people’s’ daily lives.

  1. I love this! Go green 🙂

    I told our house helper about this, and had her watch the vid. She’s happy they’re gonna have light in their house in the province and want me to say thanks to you 🙂

  2. hi jenni! as far as i know, coke has not been formally onboard this project. the myshelter foundation team has been trying to reach them though so if any of your readers could help facilitate the introductions, it’ll be greatly appreciated. 🙂
