  A discarded plastic bottle filled with water could help beat darkness in millions of slums, where people are forced to live without power. The bottle will serve as a light bulb, which help lighten a room during the daytime.
  The Vijnana Bharti in association with National Environment
  and Energy Development Mission has replicated an Indonesian formula to use sunlight to provide free-of-cost electricity to slum dwellers.
  The process was displayed during the third Bharatiya Vigyan Sammelan and Expo, 2012, at Lovely Professional University in Jalandhar on Thursday.
  Jai Kumar, general secretary of Vijnana Bharti describing the process said, “A plastic bottle is filled with water and hung from the roof of a room with no windows. One half of the bottle remains exposed to the sunlight, whereas the other is inside the room from the ceiling. The outside light refracts and lights up the dark room. The only drawback of the water bulb is that it is functional only from sunrise till sunset. As the sun goes down, the light dims and it doesn’t work at night.”
  He added that they were spreading awareness about the innovation with the help of 1 lakh volunteers, including students.
  “The Vijnana Bharti has started creating awareness about this basic physics principle among jhuggis of Madhya Pradesh, Punjab and Maharashtra. It is an arrangement that will yield illumination equivalent to that of a 100 W bulb,” he maintained.
  Interestingly, if some bleaching powder is added to the water, the light will scatter in the whole room. “The light will scatter more in the room if we add beaching powder, soda or chlorine tablets. The bleach prevents the growth of algae so that bulbs could last long,” Kumar said.
  
  He added that during night hours, the reflection of halogen bulb from the streetlight could be used as a source for illumination.
  “The organisation’s goal is to use this environment friendly and readily available source of illumination and an alternative source of daylight to brighten 20 crore homes in the country that have no access to power,” he added.
  Kumar said, “The nature has bestowed many priceless gifts to the mankind. What is needed is to identify them.”
