If you dig up the various stories about the recent increases in the number of blimps in the world, you'll read that one of their minor problems is that people are always using them as targets. It's not actually all that big a problem, because even very large bullets leave only a slow leak. Part of the routine maintenance is plugging all the small holes in the fabric. Every few years they have to replace the fabric.
It's more of a problem when the bullets miss the fabric and hit the gondola. Flight crew in one of those advertising blimps over a football game can be a risky job in some areas.
But this wouldn't be that much of a problem for a blimp at 21 km altitude. It would take a rather high-powered rifle to hit something that far up, and your typical suburban redneck probably wouldn't have anything with that kind of power.
They could be a target during military (and terrorist) operations. Even then, though, blimps are difficult to bring down. Your typical small missile, even if it hit and exploded inside the baloon, would just leave a lot of small holes, causing a slow descent. It would take a direct hit on the gondola to put it out of action quickly, and that's not an easy target.

With a blimp, the end going into the cellular network must also be wireless. What you've then introduced is a wireless repeater, which consumes twice the bandwidth compared to a land-based tower.
The angles at which land-based towers transmit allows its beams to penetrate windows for indoor coverage. A blimp that flies higher would not be able to penetrate several floors (or even just ordinary roofing) to provide the same coverage, especially right underneath itself.
If the blimp cannot be kept stationary enough for doppler sync purposes, then you'll need significantly more complex software to deal with the fact that both the blimp and the handset are moving.
Not impossible, but there are significant obstacles.

This is, hopefully, much cheaper than geosync satellites. PLUS you can bring them down for maintenence (unlike geosync). So therefore, the machines can be less redundant (read "expensive") than satellite technology.
Sounds like a great solution if they can successfully keep them in place. If cheap enough, this technology could replace the need for ALL large radio towers. (Those towers ain't cheap either, you know)

Fuel cells work by combining, usually, oxygen and hydrogen, releasing electricity and water. They are common on manned space flight because they provide drinking water and power, plus also a reliable energy dense form of electrical power. This ability to fullfill many roles and having no waste products makes them a good engineering solution, and they are highly robust.
However all fuel cells need as supply of gas to continue working. Conceiveably you can capture the waste water, electrolyse it and recompress the oxygen and hydrogen produced back to thier liquid forms for storage - but that is a highly complex bit of engineering.
As such satellites, to my knowledge, use batteries of various chemical regimes. I would expect the airships too as well - weight is not a huge problem on an airship as the envelope lifts pretty much what you want for 'free' unlike an aircraft where you have to expend energy to keep aloft, so normal chemical cell technology is a simpler engineering solution.
If cheap enough, this technology could replace the need for ALL large radio towers
As mentioned elsewhere these will not replace towers. Any tower that has one side connected to a landline (broadcast towers) will still have to be there. Any tower that boosts and retransmits (relay towers) could be replaced by this sort of idea, but some of those relay towers transmit at very high wattages - I question whether the solar collectors would be able to collect enough power to do the same. Especially, when accounting for daylight and losses in charging/regualtion systems on the battery bank, you probably need to achieve 3 times the rate of your energy consuption on your collection system. But certainly scenarios where you need a geographically wide coverage area at not a great power output, this idea could work very well.

An autonomous system like the airships would need would not do that, even if there was some form of active monitoring by a ground based 'pilot' who could take over in the event of an emergency they are not physically there so may not be able to assess the emergency as well or as quickly as a pilot in an airplane. After all if there is a problem with the control surfaces on an airplane you have the chance of going into the cabin and actually seeing what is wrong rather than relying on instruments.
Additionally air flight paths are by and large routed away from major centers of popluation for that very reason, unless there is no alternative. The airships would require to be over populated areas to achieve thier tasks. Of course this leads to some interesting thoughts on exactly how the FAA(US)/CAA(UK) would view piloted and autonomous aircraft sharing airspace - would air traffic control be able to override the autonomous aircraft directly in an emergency, or would a ground based operator need to do it?
And my final thought is people are worried, probably rightly, by the safety of autonomous aircraft. We value life highly, so the level of safety engineering that goes into a piloted aircraft is much higher. If the aim is to provide cheap as possible autonomous systems, where all you lose is some money covered by insurance, then rightly we need to question if the safety engineering will be as high.

Huh? These things were several times longer than a 747 and had a cruising altitude of only about 1000 feet. The Hindenburg flying right over you would not only be visible, but it would blot out much of the sky.
Even the high-altitude Zeppelin bombers of WWI were unpressurized and maxed out around 17000 feet; they were certainly not invisible.
Maths... (Score:2)
www.thirdreichforum.com(full accident report) [thirdreichforum.com]
Both these suggest the length of the Hindeburgh (apparently a development of the Zeppelin type) was 804 feet, and cruised at around 1000 feet - although it appears to be able to fly at a few thousand to avoid weather systems.
Now using 2 * pi * r to calculate the circumfrence of a circle with the radius as the altitude, and then divide by the length of the airframe, we can deduce that the arc of the length on the airship is:
2 * pi * 1000 = 6283
(804 / 6283) * 360 = 46 degrees
So turning that into a more accessable figure that would be the same as 72 metre long object at a range of 100 metres - definately visable!!
[ sin 46 * 100 = 72 ]
Even if the bombers fly at 17000 feet the figures still suggest it would be potentailly visable:
2 * pi * 17000 = 106814
(804 / 106814) * 360 = 2.7 degrees
sin 2.7 * 100 = 4.7
So same as a 5 metre object at a range of 100m. That would still be visable to careful observation, although use of a disruption colour scheme would help it evade detection. Certainly not invisible.
For these Statolites, the figures would be:
18 metres is approx 60 feet
2 * pi * 18000 = 113097
(60 / 113097) * 360 = 5.3e-4 degrees
sin 5.3e-4 * 100 = 9.25e-4
Thats equivalent to an object of 1mm length at 100m - invisible to all intents and purposes.

Aircraft are divided into airplanes, rotorcraft, gliders, airships and balloons.
An airship is sustained by a lighter-than-air gas and has mechanical propulsion; a balloon is sustained by a lighter-than-air gas and has no propulsion of its own.
Airships are divided into dirigibles (synonymous with zeppelins) and blimps. Dirigibles have internal frames for rigidity; blimps have only the internal gas pressure for rigidity.
There has never been a spherical airship before, and I'm somewhat at a loss as to why anyone would build such a thing; controlling it would be a bitch. So if these things do come to pass, they will be sui generis.
The word "dirigible" causes some confusion, because it does indeed mean steerable in Latin, and blimps are certainly steerable; however, the aviation community decided to use "dirigible" as a synonym for "zeppelin" back when World War I had made German names unpopular. The Hindenburg was a dirigible/zeppelin; Goodyear has blimps.
