Quite true! Years back, in the course of doing a paper on WWII I had the chance to read lots of saved personal letters to/from Europe and there were occasions of redaction.
You couldn't mention where you were, soldier's names, weather, military details, or other information that could conceiveably provide any benefit to the enemy. Several letters also contained a mass-produced page from the Government (inserted by the censors) explaining this and asking for cooperation.
Emails and telecommunication must be a hell of a lot harder, if not impossible, to maintain security.
I used to drive an ambulance (vounteer EMT in my town). They had a whole procedure for going through redlights: lights/siren, how far away to start sounding the siren, degree of emergency of the call (a whole list of possibilities and a list of "not necessary"'s), speed to slow down to when crossing a red intersection, and so forth.
TO a call: always. En route to the hospital: depended upon the call and whether it was an emergency or a lower priority. ALWAYS had to run with lights when there was a patient(s) in the vehicle; siren depended upon the nature of the call.
The lights in town didn't have lockups on them (would go 'every-way-red' when they sensed oncoming strobes) and, so, crossing a red was no small thing for ambulance, fire, or cops.
Remember though: the 'cloud' wouldn't travel too far since the particles wouldn't stay suspended (for lack of air), and would tend to move pretty much laterally rather than vertically if something was dropped; and even then not with much energy. Kicking dust would be about the same - it's kind of hard to accidentally kick dirt 'up' with much force.
Did you ever see any of the Apollo surface footage? Even the particles in the 'rooster tails' kicked-up by the Lunar Roving vehicles used by Apollos 14/15/16 (http://starchild.gsfc.nasa.gov/docs/StarChild/spa ce_level2/apollo15_rover.html) behaved just as the laws of ballistics prove and didn't 'hang' too long.
Why don't they store the shuttle under some kind of solid covering that, on launch day, will open like a dome on a sport field? Or from some form of underground "silo"? It would help protect the shuttle, or, in the future, whatever they are using to go to space.

Interesting post. Good information. A question, please: what does it take to crack water and use the H2?
(from http://en.wikipedia.org/wiki/Molecular_mass) "...the exact mass of hydrogen-1 (the most common isotope) is 1.00783, and the exact mass of oxygen-16 (the most common isotope) is 15.9949, so the mass of the most common single molecule of water is 18.0105 u..."
Doing the math, hydrogen is 11.19% of the mass, and the HoH is inert. Is it any better than what they're doing?
If the government wants to take away our channels so they can sell the airspace and turn an insane profit on re-renting that "free" airspace ("free", apparently, in that it costs _them_ nothing), then the very LEAST they can do is give me a break on a decoder.
Some of us can't afford cable (or new, over-priced screens) and must rely on RF-broadcast television.

Actually, there should be a lot less than that since some characters are always letters and some characters are always numbers.
If the sealant mixes with the dust, mostly acting as a binding agent, then it would be far more space efficient. Take glue, mix with dirt, spread over surface. Most of the sealants volume would then be native dirt, which is exceptionally plentiful.
All true and believable; but I don't know - I'd like to see an efficient (low-mass, low volume, high dependability) liquid system proven in a benign Terran environment first (I can't think of any similar uses on Earth - anyone else?). I believe woven (or even extruded/rolled) materials have already proven themselves for such situations and uses, and mankind already has sufficient familiarity with the concept and the technology to make durable materials. (also, remember the KISS principle)
Roll it out, use it, roll it up, use it somewhere else, cut it up if you need to make a sling to carry something or use it as shielding - multiple uses and versatility in such an isolated and hostile environment seems like it should win-out over a single-use, single-purpose, more-complex system.
Rather than a sealant (consisting of tanks, liquid, and associated equipment that could malfunction ), how about a (literally) 'carpet runner'? They're walking from place-to-place? Most likely in a straight line, how about something like landscaper's cloth?
Okay, "high-tech landscaper's cloth". Utilizing Tang®, and Velcro®. And frickin' lasers.
Seriously, rolls of cloth would be easier to carry/stow (less volume & mass than application equipment, more reliable), more durable than a sprayed coating, and I'm sure a cloth could have more than one emergency purpose (should the need arise).

That was one of the [more] stupid parts of the movie. Be observant: the extraction tool was the size of a golf ball but the part ultimately removed was a lot smaller.
Patent applications propose a lot of things (claims) in the hopes that, someday during the life of the patent, if the technology is finally evolved that far, the assignee can make $$$ off of licensing.
I'd really like to see a system capable of the kind of detail, precision, speed, and tracking required for covert iris analysis, in real time, from a distance.
LSS: just because it's in a claim doesn't mean it'll ever happen - the name of the game is to add as many related claims as possible to cover all possible future concepts and variations.
And, then, there're always 'mirror shades', contacts, and corneal lenses if you're really trying to beat the system.
The "experiment" described in TFA where the debit was halved by plugging one out of two holes in a bottle is false as there is only one hole at present.
Worse than that: apparently they don't understand the difference between internal pressure and gravitic flow.
You plug all the holes in the bottle and it's still going to be at the same pressure (head). No big deal. BUT, you plug the hole(s) that internal pressure is forcing the mud through (against gravity, mind you), and you're going to have a 'situation' at hand.
Pressure builds (unlike the emptying bottle) and velocity/flow/erosion will increase.

I still find Appleworks v6.2.2 suits most of my needs - it runs fine on OS 10.4.7 (and the installer CD has the windows version on it too).
Still runs, still enough features, you have to really try to abuse it HARD to make it crash.
