It almost sounds like a joke — a solar-powered light bulb — but it’s not, and the guy who invented the Nokero lives right here in Colorado. The Denver Post has a story about Stephen Katsaros’ invention and the way he intends to get it into the hands of people who need and want it.

As soon as he saw the first molds of the bulb coming out of the factory, Katsaros, 37, quit the legal firm where he worked as a patent agent and devoted himself full-time to Nokero.

His plan is to target countries such as India, Indonesia, Nigeria and Pakistan, where hundreds of millions rely on expensive, carbon-spewing gas lamps but income is high enough to afford a $15 lamp. Demand is higher in places such as Ethiopia, but the population is too poor to afford the lamp, Katsaros says.

“This is not a charity,” he says. “We are using capitalism as a method to improve people’s lives.”
