Google (GOOG) unveils Project Loon, an initiative aiming to provide Web access for the entire world using (believe it or not) hot-air balloons. The balloons, meant to connect "rural, remote, and underserved areas," would be "carried by the wind at altitudes twice as high as commercial planes," and deliver 3G or faster speeds. Google modestly admits the idea presents challenges, but says its use of wind/solar power to control where the balloons go, and algorithms to determine where to send them, could make it work. A pilot program is underway in New Zealand. It's safe to call this one of Larry Page's moonshot projects.
