Google Floats Balloons For Free Wi-Fi 115

Posted by Soulskill from the shannon-hartley-bernoulli-theorem dept.
New submitter BrokenHalo writes "Google has revealed that it has 30 balloons floating over New Zealand in a project to bring free Wi-Fi to earthquake-stricken, rural or poor areas. They're calling it Project Loon. '[W]e’ve built a system that uses balloons, carried by the wind at altitudes twice as high as commercial planes, to beam Internet access to the ground at speeds similar to today’s 3G networks or faster. As a result, we hope balloons could become an option for connecting rural, remote, and underserved areas, and for helping with communications after natural disasters.' Eventually, as the balloons move across the stratosphere, consumers in participating countries along the 40th parallel in the Southern Hemisphere could tap into the service. The technology will be trialled in Australia next year, possibly in Tasmania. If the latter happens to be true, then you'll probably hear the telcos' screams in New York."

      • Is there any reason not to use hydrogen for this application? It's much cheaper. These balloons run unattended. They could be designed to automatically vent their hydrogen if their altitude gets too low. That would prevent any danger to people on the ground.

          How do you know they are not using hydrogen? TFA does not say what gas they are using. So maybe they are using hydrogen but don't want to say so because of the idiots that associate it with the Hindenburg or hydrogen bombs. Thousands of people drown every year in a liquid that is 2/3 hydrogen, so there is no denying that it is dangerous stuff.

        Helium? I think we are wasting so much.

        The market is already fixing this. Helium prices are rising [bloomberg.com]. The primary reason for this is shale gas. Helium is a byproduct of natural gas production. Some gas wells in Texas contain as much as 4% helium. Gas wells outside the USA contain very little helium, making America the dominant producer. But America is switching to shale gas, which contains very little helium, and the helium producing wells are being shut down because they can't operate profitably with historically low gas prices. So helium prices are climbing, and frivolous uses are being curtailed. Disneyland Tokyo has already stopped selling helium balloons of cartoon characters.

        No, your laptop by itself couldn't, but the protocol is certainly capable of handling the distance if you tweak the timeout settings and have a powerful radio and a good antenna setup.

        They probably wouldn't actually use wifi though, some of the cellphone-based standards are more suitable for this type of system.

        To use this you would probably need an antenna and modem set up on your house, much like satellite Internet. It would still be a challenge though, I've streamed data off a balloon before and we were tracking it manually with a high gain antenna and used extremely slow data rates. They're going to be limited to solar power too, which limits their radio output power a lot.
