Solar-Powered Light Bulb Is One Denver Inventor's Brilliant Idea

Solar-Powered Light BulbIn his spartan Capitol Hill office, Stephen Katsaros explains how Nokero, the affordable, durable, sun-fueled light, can help the 1.6 billion people worldwide without electricity and wean them from burning dangerous kerosene lamps. At the China factory poised to make 600,000 to 1.2 million bulbs a month, the rain-proof lights are made with impact-resistant plastic and special computer chips to prolong battery life. Four solar panels charge the light, and they should last five years, providing up to four hours of light on a single charge. Already Nokero bulbs are trickling into 33 countries, where tens of millions live without electricity. Bought in bulk, the bulbs cost about $6 each. Retail, they run about $15.
