Google is launching balloons into near space to provide internet access to buildings below on the ground.

About 30 of the superpressure balloons are being launched from New Zealand from where they will drift around the world on a controlled path.

It's hoped the equipment will be able to deliver 3G-like speeds to 50 testers in the country. Initially access will be intermittent, but it's hoped in the future, with a large enough fleet, a more reliable connection can be provided.

Such ideas for the use of these balloons include the possibility of them being utilised in disaster-hit areas, to aid rescue efforts in situations where ground communication equipment has been damaged.

Such a simple idea however does not come without its problems, simultaneously navigate thousands of the high-altitude balloons around the globe's wind patterns will no doubt prove to be a difficult task to get right.
