Lighting up rural India

A power engineer's attempt to ​provide electricity and improve the socio-economic positions of rural people

​In India, one of world’s largest, most populated countries, over 74 million rural households live without power. Children study in harmful smoke, average people spends 5% of their income on lighting fuel, people burns wood for lighting.
A single kerosene wick burns an estimated 80 liters of fuel, producing more than 250 kilograms of carbon dioxide per year. Multiply that across the developing world and kerosene lamps emit 270,000 tons of black carbon annually – equivalent to 240 million metric tons of CO2.
This is where Debasish Dutta, a DIY hobbyist by passion and a power Engineer by profession stepped in. After completing his B.Tech from College Of Engineering and Technology, Bhubaneswar  and M.Tech  from NIT Durgapur, he started to work on projects related to solar energy and Arduino.  To help people living in villages, he made this solar light bulb for providing a low cost solution by replacing their harmful kerosene lamps. This will empower the world’s poor to replace kerosene with clean solar-powered light.
He  prefers to make using used things that can be recycled. He made this solar light bulb by using used items and few electronic components.

F8MZK8CI6RSWXAX.MEDIUMFeatures:
1. One day charging can give light up to 20-22 lumens (about three times the brightness of a kerosene lamp) for the entire night.
2. A 2000mah AA battery can be charged fully in two days bright sun light. You can use the hanger as well as the multipurpose stand for charging. Just hang it on a wire outside or place it at your window.
3. Uses high quality AA NiMh battery which can work at least for 5 years.
4. Uses a high quality solar panel to charge the battery.
5. Automatically switches off in bright light to save charge and switch on in dark.
6. Battery over discharge protection circuit.

Advantages:
1.Improves literacy: Solar light bulb improves literacy, because people can read after dark more easily than they can by candle or kerosene lamp.
2. Saves Energy: As the light is bulb is charged through solar energy (free energy) it saves energy.
3. Reduces air pollution: Use of solar light bulb decreases the amount of local air pollution. With a decrease in the amount of kerosene used for lighting, there is a corresponding reduction in the amount of pollution produced.
4. Reduces greenhouse gases: Solar light bulb gives light with no carbon dioxide (CO2) emissions.

Uses:
1. Night Lamp
2.Reading Lamp
3.Portable Emergency Light
4.Camping and Hiking Lamp
5.Garden/Lawn Light
