An anonymous reader writes "Google is reportedly looking into investing in or buying a company called Space Data, which provides wireless voice and data services to remote areas with a fleet of weather balloons fitted with transceivers." My mind is sorta tripping over how something like this could work, but I gotta admit that the idea is really cool.

As long as they're just spamming platforms that last for a day or two, the idea is pretty much doomed. The loss rate is going to be astronomical, and sending guys out in a truck to pick 'em up is in no way cost efficient.

* Building a balloon that could survive a three-day trip across the Pacific and then automatically drop its warload was technically challenging. Since a hydrogen balloon expands in the sunlight and rises, then contracts at night and falls, the Japanese engineers had to develop a battery-operated automatic control system to maintain altitude. When the balloon descended below 9 kilometers (29,500 feet), it electrically fired charges to cut loose sandbags. The sandbags were carried on a cast-aluminum four-spoked wheel, and discarded two at a time to keep the wheel balanced. Similarly, when the balloon rose above about 11.6 kilometers (38,000 feet), the altimeter activated a valve to vent hydrogen; the hydrogen was also vented if the balloon's pressure reached a critical level.
The balloon had to carry about 900 kilograms (1,000 pounds) of gear, which meant a hydrogen balloon with a diameter of about 10 meters (33 feet). At first, the balloons were made of conventional rubberized silk, but there was a cheaper way to make an envelope that leaked even less. An order went out for ten thousand balloons made of "washi", a paper derived from mulberry bushes that was impermeable and very tough. It was only available in squares about the size of a road map, so it was glued together in three or four laminations using paste derived from a tuber with the Japanese name of "devil's-tongue".

That's an awful waste of resources not to mention what happens if someone is transmitting a signal when the balloon in your area pops? How much does all this constant launching and recovering cost compared to just putting in a tower despite the remoteness?
I can see using these balloons for limited times, such as emergencies, or battlefield conditions where there are no cell towers (as the article intimates) but for every day use? I don't think so.
And what is this 'floating gently back down to earth' stuff? Unless they have a parachute, the tranceiver will not be floating gently back down to earth when the balloon pops. It will be plummeting.

If you make a tear in balloons fabric - it will slowly descend as the helium inside the balloon leaks.
Of course, if you tear balloon apart - it will fall lake a lead weight. But it's rather hard to do.

I spent a year launching weather balloons from Antarctica [gdargaud.net]. They take about one hour to reach 20~30km altitude, then the latex tears up (remember, as the pressure decreases, the volume increases) and the plummet to the ground in less then 10 minutes. In rare cases what's left of the latex will form a parachute shape and they will drop slower.
If you fill them more, they go up faster and blow up earlier (as the latex reaches its maximum thinness earlier). If you underfill them, you get less buoyancy [wikipedia.org], and they can float for a long time if they don't go up to where they'll pop, which is probably what you want here.
But I have to remind you that:
- latex is expensive (at least for daily balloon launches, you are OK with your S&M fantasies).
- helium is very expensive and world quantities are limited and will run out before petroleum does.
- a standard weather balloon can lift only about 200 grams, which pretty much limits the quantity of battery and thus the wifi power range you can carry.
All that being said I think it's a neat idea, but not as much as solar powered ultra-light drones.Parent
Cost Analysis (Score:3, Interesting)
With even the cheapest base station hardware, helium, balloon (at say, $5000 per unit), costs would exceed $14.6M/year per site.
This does not include the labor to continuously manufacturer, transport, and launch equipment.
At a rate of $50/month per subscriber, you would need about 25,000 to break even on base station--hardware alone. This does not include the uplink facility, bandwidth costs, and business administration costs.

The coverage should be ~50 mile radius.
To build a base station to do the same thing you would need at least a 300' mast and microwave links between them, plus you have to lease the ground. I don't think you can pull it off with less than a 3-year payback; you also need more prime airwaves.

"Rural and remote" suggests difficult terrain, dense cover, lakes and ponds, and very few people. I don't think we are talking about the cornfields in Nebraska.

If you tether the balloon, the altitude has to be very low or else the cable would be a hazard to aircraft. The whole idea is to put these up so high that they are well out of the way of air traffic. Also, the higher you go, the bigger the area you can cover.
Think of these as cheap, low altitude satellites.
