Adopt a light

   A person from brazil by the name Vilvoldo came up with a wonderful idea of a project known as Water bulb.These works like this in the slums of Korogocho,most of the residents use a chimmy light which emites tar (smoke) which affects their respiratory organs.(this happens during the day) So Vilvoldo came up with the technology where plastic bottle would be filled by water so during the day the light from the sun burn's he bottles this generating light inside the dark rooms.
