A liter of light

What do you get with sunshine and an old plastic bottle filled with water and chlorine? Thanks to Alfred Moser and a group of MIT students, you get a 55-watt solar bulb that refracts sunlight! It’s powerful enough to light up a home but more than that it’s environmentally friendly, inexpensive, and easy to make.

The Liter of Light began in the Philippines with one bottle light. Eventually, the movement grew to brighten up 28,000 homes and the lives of 70,000 people in Metro Manila alone. Now Liter of Light is present in India, Indonesia, and even as far away as Switzerland.
