Here is new beginning. A good news for power starved parts of world and also a good one for environment.A Hong Kong-based company has introduced what it bills as the world’s only solar-powered light bulb with the hope of reaching millions of people with little or no access to electricity.
The N100 solar bulb is about the size of a standard incandescent bulb and has four small solar panels in its rainproof plastic housing. Five LEDs and a replaceable NiMH battery inside provide up to four hours of light when the device is fully charged. People hang it outside during the day and then turn it on at night.
