How Volunteers Use Recycled Plastic Bottles To Light Up Impoverished Countries

By Brian Spaen

A unique project that features a used plastic bottle and solar panels has made green energy much more affordable in poorer countries. MyShelter Foundation has created the Liter of Light, which gives people light indoors during the daytime and can also be used at night with stored energy from the sun. The project kicked off in the Philippines and now spans 15 different countries.

These bottles are filled with water and a few tablespoons of bleach. The bleach keeps algae from building up in the bottle so that it can last for up to five years. They’re placed in the holes of galvanized steel sheets that are located on top of shelters. It provides light for structures that don’t have any windows for the sunlight to come in.
