Bright Idea

If you enjoyed reading the recent post on low-energy Futuristic Lightbulbs that can last up to 17 years, then this new idea should lighten your day. Given that almost 2 billion people live without electricity, entrepreneur Stephen Katsaros has invented a solar powered light bulb in hopes of bringing light to the developing world.

The 6-ounce Nokero bulb absorbs the sun's energy into a replaceable battery by way of four photovoltaic panels, which gives power to five white LEDs inside the weatherproof, plastic casing. The bulb will glow for four hours when fully charged, and a full day outside will provide enough energy for about two hours of light. Currently they are $15 each, but the price will drop for bulk orders.

Although the bulbs will likely appeal to the outdoorsy type or patio lovers, Katsaros' major focus is making them available to those in the developing world. "We are trying to reduce the cost so that the 2.8 billion people in the world who make less than two dollars a day can afford this." Nokero bulbs could provide a clean and safe alternative to the commonly used kerosene lanterns, which emit toxic fumes and start fires responsible for over 1 million deaths worldwide.
