solar bottle bulb

Solar bottle bulb a new concept and hope for the slam area in Manila. MIT students invent that by using Plastic bottle without consuming any electricity. CNN reports that, 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. The process of making solar bottle bulb is likely that-  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.
