Plastic bottles have become a sustainable way to light many homes in poorer sections of Manila in the Philippines, where many houses are built too close to each other to allow for windows, CNN reported. For many residents electricity is unaffordable or unavailable, forcing them to work and live in the dark. But a new project has shined a light in the darkness - literally. Based on an invention by an engineer from Amy Smith, an engineer from the Massachusetts Institute of Technology, the recycled plastic bottles are filled with water and bleach and then fixed into holes on the roof. The bottle bulbs then refract the sun's rays to create 55-watts worth of light. The project has reached about 10,000 homes and aims for one million by 2012.
