Google’s floating network in sky — Project Loon — won’t just be mobile, following the stratospheric wind currents; it will be the very definition of a evolving network with new transmitters launched into the sky every 100 days. In a new video on Loon's Google+ site, Google explained that each Loon balloon is designed to stay aloft for three trips around the globe.
A key component of the Google [x] Lab project to deliver Wi-Fi to remote parts of the world via souped-up weather balloons, according to a new Google video. Its Latest video takes it a step further: tearing apart one of its blimp-tracking antennas and explaining how it works. Every unit houses a radio,
Pam Desrochers, Google's balloon manufacturing manager said “The most important part about keeping balloons in the air for a long time is making sure that they are leak-proof “. The surface area of the balloon is really vast, about 500 square meters, and it provides a lot of opportunities for little pinholes and leaks, which can shorten the life of our flight.”
The balloons will be subjected to big changes in temperature as the sun rises and sets, causing its internal pressure to change dramatically. Meanwhile, Loon will be “steering” the balloons in the stratospheric winds by pumping air in and out of them creating additional stresses.
While originally the balloons that were tested in Project Loon's demo in New Zealand were made out of polyethylene film, the video makes it sound like Google is still undecided on what kind of material will best suit its balloons. Google now appears to be testing all manner of materials, subjecting them to durability, temperature and leak tests.
