Shanty town homes in Manila are often built so close to each other that they have no windows or natural light. With electricity unaffordable or unavailable for many slum-inhabitants, many families often have to work, do chores, and eat in near darkness.
Now a simple innovation called the "Solar Bottle Bulb" is popping out of roofs and illuminating the lives of many.
"Solar Bottle Bulb" was inspired by engineer Amy Smith, from the D-Lab MIT. Illac Diaz, of non-profit My Shelter Foundation, brought the simple, cheap and innovative technology to the Philippines through his project, "A Liter of Light."
Fixed into holes in a corrugated iron roof, the "bulb" is a recycled plastic bottle that contains bleached water. Bringing more light than a traditional window that can crack or leak during typhoon season, the bottle bulbs refract the sun's rays to create 55-watts worth of light.
