In order to capture day light and concentrate the same inside a dark room, particularly in urban slum or rural areas which lack electricity supply, a low cost and energy efficient Micro Solar Dome has been tested and developed.
- The Micro Solar Dome (MSD) is a clear and green energy initiative of the Department of Science and Technology.
- This project will also supplement the Green Energy initiatives.
- The Micro Solar Dome (MSD) is a day and night lighting single device unique in its features, that has a transparent semi-spherical upper dome made of acrylic material which captures the sunlight and the light passes through a sun-tube having a thin layer of highly reflective coating on the inner wall of the passage.
- It also contains a lower dome made of acrylic. There is a shutter in the bottom of the lower dome which can be closed, if light is not required in the daytime. It is leak proof and works throughout the day and 4 hours continuously after sunset.The entire development activities were taken up by an R&D Organisation under the aegis of the Department of Science & Technology.
- The potential users of this device are the 10 million off-grid households in urban and rural spaces and several folds more that do not have reliable access to electricity. When these Surya Jyoti lamps, giving an illumination equivalent of a 60W incandescent lamp, are installed in 10 million households it would lead to a saving of 1750 million units of energy.
- It would also lead to an Emission Reduction of about 12.5 million ton of CO2.
