Qatar figures out novel way to cool crowds for 2022 World Cup
March 28, 2011 by Bob Yirka
(PhysOrg.com) -- In what should be viewed as a contender for some sort of science prize for originality, researchers at Qatar University have come up with an idea whereby artificial clouds might be used to hover over stadiums for the 2022 world cup, which the nation will be hosting eleven years from now, to overcome nearly non-stop sunlight and extreme heat.
Qatar, the tiny, oil rich, barely a bump on the Arabian peninsula, middle eastern country, was chosen over much larger possibilities, despite protests by several other countries, and now must figure out a way to host soccer matches in outdoor stadiums in the summer, in a place where temperatures average 115 degrees Fahrenheit for all of July.
Saud Abdul Ghani, head of the mechanical and industrial engineering department at Qatar University, and his team have come up with plans for a helium filled dirigible of sorts, constructed of very lightweight carbon fiber and other super-light materials, that would be flat, as opposed to the more familiar spheroid blimps often seen hovering over sporting events at other venues. By making them flat, the artificial clouds could both take advantage of solar energy to power the four electrical motors, and create a much bigger sun block. The clouds/dirigibles would be large enough to cover both the field and stands, and would be steered and held in place via wireless remote control by someone on the ground.
The artificial clouds would serve as an additional aid in cooling players and fans (and practice facilities) as engineers for the planned stadiums are expected to come up with a way to install some form of solar powered air-conditioning as well.

When Qatar was selected to host the 2022 World Cup, many people expected the games would be moved to the winter, when temperatures would be more mild; FIFAs president, Sepp Blatter, though has been adamant that the games would be played as scheduled, insisting that trying to host a World Cup during the middle of the regular soccer season for most teams would be untenable.Each cloud is expected to cost somewhere in the neighborhood of half a million dollars.

ereneon: An indoor stadium for 100,000 plus football fans is too big of a challenge to build - also cost prohibitive. It's not like there's a huge demand for a stadium like that in a place with 115 degree fahrenheit average temperatures during summer. I mean, who would want to live there in the first place? Go figure.
I think that using wireless remote control on a hovering cloud sized dirigible is a stupid idea when all you would have to do would be to anchor it down with cable at the four corners. That would be a lot cheaper. Why, they could shade the whole country with a flotilla of those things.

A person's vocabulary generally grows with age. As they encounter more language, they internalize more of it.
Since you're proposing that we limit writing to only those words that we all 'should' know, at what level should we limit our writing?
Should writing above the 5th grade level be discouraged? Too low? Surely nobody should be expected to actually learn anything after they've passed the 12th grade.

Joking aside, I gather that you looked up the word to find out what it meant. Congratulations, that is how learning happens. Celebrate that learning!
Don't fear ignorance (don't celebrate it either), relish it as opportunity to learn. We are all ignorant about things until we learn about them, and each time we learn, the universe becomes a slightly more interesting place.

A fixed shade is not going to be able to adjust its position as the sun moves through the sky. This means it will have to be larger than the dirigible in order to consistently cover a given space throughout the day. The free-floating dirigible also has the benefit of being able to float higher (cable is heavy after all) and thus will block out the sun but less of that pretty blue Qatar sky.

Are you under the false impression that each word has a "level"? Do you consider "dirigible" a "higher" level word? Interesting. Here's a thought: How about at the level of a 40 year old, 29 year veteran systems architect, a CIO, a history expert, and an electrical engineer?

You're preaching to the choir brother. While learning new words is great, choosing the right ones to use shows intelligence.
From a view point of maximizing communication, dirigible is an unneeded and lessor used and lessor known synonym, and as such, communication has little to no need for it. For example: There's a similar type of problem in my field of computer programming: When we write source code, we're creating two products. 1 is the end product that the users use, the other is the source code that other programmers will have to eventually maintain. We do a disservice to our fellow programmers when we make arcane labels for objects.

In programming this is usually done with a malpractice in the form of making cryptic, made up, abbreviations for everything. To maximize the intent (the communication) of what the program is intended to do, we avoid cryptic names and abbreviations to convey to the other programmers what we intended. Instead we use commonly known words for labels to increase the communication and usability of our source code.
Spoken and written human language is no different, logically. I realize there are pseudo-intellectuals who have a false pretense that wasting mind space with rarely used words puts them "above" other people, but they don't realize how silly and irrelevant they appear. There are few things more annoying than the type of person who holds themselves in such high regard based on more or less, useless (except maybe on "Jeopardy!") trivia.

Words don't have "levels", they have "usefulness". When a thought has multiple labels for it, logic dictates to use the most commonly known word, otherwise you fail at your task of communication. There are, of course, times when one of the synonyms has a slightly different nuance and is also somewhat uncommon, but that nuanced meaning is important. That's not the case here.

As an immigrant at the age of seven, in second grade I took it upon myself to read the entire Roget's Thesaurus. When I was in sixth grade, my teacher would give me until the next day to write out three pages of the Oxford English pocket dictionary every time he felt that I deserved it. Let it not go unsaid that I was destined to become a master of the English language. Chalk much of it up to self-motivation.
The correct definition of "savant" is: A learned person; a scholar. Surprised? Too many people throw away the books once they get their walking papers from whatever academic institution they earned them from. That's a sad thing, because as you may have heard, "Those that can, do; those that can't, teach."

Interesting. Admitting to not knowing one particular word and you derive "not have a huge vocabulary" from the one word. Amazing.
Yep, being attacked from multiple points and defending myself on only a select few (which requires a certain amount of minimal text) and I get further attacked for defending myself. Jeesh!

I understand and expected this misperception. I appreciate your response (and I fived it, BTW). As I explained above, it's not that it's a "big word", it's that it appears to be a poor choice for communication as it does not appear to be a well known word, in spite of the claims to the contrary in this thread, and after a quick survey of my educated peers, some of whom, like myself, consistently score around the "genius" mark on IQ tests (I apologize for pointing that out, as it always triggers negative reflex responses), hardly any of them had ever heard of it either, much less, even knew what it meant.

I doubt anyone other than a select vocal few here is showing any contempt for your (and your peers') ignorance of the word 'dirigible' as opposed to your need to post five paragraphs defending why it's ok for you not to know it and why it was a poor choice for the author to utilize despite its accuracy. It's just a bit pretentious to suggest that no one else should know the definition or be familiar with the word just because you and a few friends have never heard of it. As a matter of deduction I would say that it's probable you and said peers all were educated at the same place and that that place chose not to include 'dirigible' as a vocabulary word in grade 5 (the latter suggestion because it was a vocab word in my school). I expect most of the negativity is due to your choice to make it a "big deal" when it really isn't, and the fact that even if you didn't know, its definition should be obvious in context with the rest of the sentence without looking it up.

First, the idea that we shouldn't use words that are not exceedingly common is a bit narrow-minded.
Second, "dirigible" scores 963,000 hits on google, a fair measure of its current use I hope we can agree. Here are some other aircraft-related words/terms that, I'd assume you would suggest should never be used to communicate:
triplane: 953,000
gyrocopter: 590,000
scramjet: 266,000
solid rocket booster: 379,000 (in quotes: 137,000)
aerofoil: 461,000
With words, 'if the shoe fits' use them. Just because an object is somewhat rare today, like dirigibles, and thus the word that aptly describes them may be used less frequently, that does not mean that we should not use the name that fits that object!
Attacking the use of such apt nouns seems... unschooled (453,000).

Again, my responses were very limited compared to the amount of attacks towards me, and again, my defense is being used against me.
In fact, they are from various grammar schools, high schools, and colleges. One went to the same grammar school as me. Two to the same high school, 2 to the same college. The rest were from different schools and most I never went to school with as I've met them in my professional life.A misperception, probably derived from the fact that I chose to defend myself. It's NOT a big deal.

Two last notes:
1. You really should read up on the 'grammatical rule' that one should not end a sentence with a preposition. Like many grammatical rules, it was completely arbitrary made up by supposed scholars, in isolation of much of English writing. Many of the greatest writers in English history have written quite effectively without ever paying heed to the 'rule'. As Winston Churchill once quipped, it is a rule "up with which I will not put!"
2. Failing that, remember "is" isn't a preposition, it's a verb.
Cheers!

Don't put words in my mouth. I never said only "exceedingly common" words should be used and you know that full well. You see, this is a type of debate tactic where one tries to stretch what one's opponent says to a much further extreme than all know was meant. It's dishonest.
I too have done some Googling. Google trends comparing blimp to dirigible, dirigible hardly shows up. Google news, the word shows up only about 15 times a month in all Google indexed news articles for the last 20 years. It goes down back to the 1940's, and spikes up in the 20's and 30's.

"dirigible" shows up on the internet far more frequently than "solid rocket booster".
What is your point again? We shouldn't use "dirigible" because it's not a commonly used word? Should we not use the term "solid rocket booster" to describe "rockets". The word "rocket" is a far more commonly used word, granted, it's not as descriptive as the term "solid rocket booster", but then "blimp" isn't as descriptive as "dirigible" is it?
You are trying to tell people what they shouldn't do. It just so happens that your arguments are based on shaky logic, arguments that, if one follows your logic, then your argument appears to state that we have to stop using a great number of aptly descriptive nouns.
I'm not right or wrong, but I am comfortable in using the word dirigible.

LOL! OMG! Oh That's so funny! I was admittedly being as as back to him. Yes, we all know that (at least, I assume we do and won't attack anyone if they didn't) and the Churchill quote is one of my favorites. One of my favorite jokes:
