The Isang Litrong Liwanag (A Liter of Light) project is bringing eco-friendly solar light into underprivileged communities.

In Sitio Maligaya in the Philippines, residents used to spend a lot of time outside. Their homes had no real lighting, electrical or natural, and even during the day it was easy to trip over belongings in the dark. Plastic Pepsi bottles, water, bleach and a little ingenuity changed all that.

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 nationwide. 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.

643 homes had been brightened at the time this video was posted, and there’s many more to go. If you’re interested in helping out with this amazing project through donations or volunteerism, check out their website.
