A solar-powered light bulb may sound like an oxymoron (what's the point of a lightbulb that only works when the sun's out?), but a company called Nokero has a prototype in the works that will charge a battery in the light bulb, making it useful after sundown. Denver-based Nokero, short for No Kerosene, hopes to offer a safe light source to the millions living without a reliable energy supply. Common non-electric light sources such as candles, charcoal, wood and kerosene are a major health threat when regularly used indoors because of the fumes they produce.
