Govt to spend Rs 1,000 cr for slum lighting project

With the aim to light up several slum alleyways, the Centre may spend Rs 1,000 crore. In the subsidies to offer a new solar lighting solution to one crore families, government is going to provide light in shanties and slums where rooms are poorly lit all through the day. 

 
The ministry of new and renewable energy has already committed Rs 500 crore for the two-year project while another Rs 500 crore is under consideration. S P Gon Chaudhuri, chairman of Kolkata-based Renewable Energy College that invented the sunlight capturing gadget confirmed the report.
 
Poor families can buy the gadget for Rs 1,100 after subsidy. If the government approves the additional subsidy of Rs 500 crore, then the cost of the gadget for the poor will come down to Rs 600, Chaudhuri said.
 
Installed on the rooftop, the gadget sends sunlight into rooms where even windows don’t let in sunlight during the day. The equipment has a special dome and a reflective cylinder, which will do the work. In night the gadget falls back on batteries charged with solar panels to light LED bulbs installed in homes. 
 
The upper end of the cylinder is attached to another dome, which is a transparent semi-spherical object like a transparent inverted bowl. It captures daylight throughout the day even when the sun is low.
 
Later it will pass the lighht down through the tube with a thin layer of mirror like reflective coating. The lower dome spreads the light across the room. The upper dome, the solar panels and part of the cylinder remains on the roof.
