Google has unveiled its "latest moonshot" out of the Google X labs which is called as "Project Loon,". It has
sent a huge number of giant balloons to beam down internet access to remote regions around the globe. Google says that balloons make sense for this purpose — they're cheap to deploy and can provide wireless coverage in areas that would otherwise be difficult to serve due to geography.
Google said that the pilot program, Project Loon, took off this month from New Zealand's South Island, using solar-powered, high-altitude balloons that ride the wind about 12.5 miles (20 kilometers) - twice as high as airplanes - above the ground. Project Loon uses algorithms to determine where the balloons need to go, then moves them into winds blowing in the desired direction.
By moving with the wind, the balloons form a network of airborne hot spots that can deliver Internet access over a broad area at speeds comparable to 3G using open radio frequency bands.
To connect to the balloon network, a special Internet antenna is attached to buildings below. The 30 balloons deployed in New Zealand this month will beam Internet to a small group of pilot testers and be used to refine the technology and shape the next phase of Project Loon.
According to reports, that the project started two years ago. Each balloon starts as an "envelope" that contains the polyethylene balloons and a 22-pound "payload" that contains all the computers and electronics.
