, CHRISTCHURCH, Jun 15 – Google revealed top-secret plans on Saturday to send balloons to the edge of space with the lofty aim of bringing Internet to the two-thirds of the global population currently without web access.
Scientists from the technology giant released up to 30 helium-filled test balloons flying 20 kilometres (12.4 miles) above Christchurch in New Zealand on Saturday, carrying antennae linked to ground base stations.
While still in the early stages, Project Loon hopes eventually to launch thousands of balloons to provide Internet to remote parts of the world, allowing the more than four billion people with no access to get online.
It could also be used to help after natural disasters, when existing communication infrastructure is affected.
“Project Loon is an experimental technology for balloon-powered Internet access,” the company said on its latest project from its clandestine Google (x), “where we work on radical, sci-fi-sounding technology solutions to solve really big world problems”.
“Balloons, carried by the wind at altitudes twice as high as commercial planes, can beam Internet access to the ground at speeds similar to today’s 3G networks or faster,” it added.
“It is very early days, but we think a ring of balloons, flying around the globe on the stratospheric winds, might be a way to provide affordable Internet access to rural, remote, and underserved areas down on earth below, or help after disasters, when existing communication infrastructure is affected.”
It works by ground stations connecting to the local Internet infrastructure and beaming signals to the balloons, which are self-powered by solar panels.
The balloons, which once in the stratosphere will be twice as high as commercial airliners and barely visible to the naked eye, are then able to communicate with each other, forming a mesh network in the sky.
Users below have an Internet antennae they attach the side of their house which can send and receive data signals from the balloons passing overhead.
