Wrong. Diffusion depends on the PARTIAL pressure difference of the helium. For helium at one atmosphere on one side, and the atmosphere itself on the other side, the partial pressure difference is one full atmosphere.
Then you don't know squat about failure analysis. First, it's MTBF, not "MTFB". Mean Time Between Failures. And it's a fundamental measure of reliability (not life) that is used everywhere.
What you call MTTF is actually MTBF. It measures the number of failures per unit time in a large population, ABSENT any consideration of wear. And when you base your expected life on this figure, you are just revealing your ignorance.
2.5 MEELION hours works out to a cool 285 YEARS, at 100% duty cycle.
MTBF is NOT the same as expected/rated life. To equate the two is the oldest, most naive misconception in the book. MTBF gives the number of drive-hours between failures, IN A LARGE POPULATION of FRESH drives. For a 2.5 million hour MTBF, if you have 10,000 drives operating, then you expect one failure every 2500 hours. That's 3-1/2 months. Right from the beginning. It does not account for wear. In fact, the failure rate function will not be a straight line. It will rise as the drives age. When the failure rate read off that line becomes very large, you have reached the limit on expected life.
Expected/rated life is determined by analyzing wear factors. They usually don't spec this figure to the user, but it is well known to be on the order of 5 years for a good quality drive that is not probing some kind of new territory in terms of design/technology.
Just for one example of how/why the drive wears out, consider the spindle bearings. They are prelubricated. That lubrication does not last forever, and there are no "oil here" stickers. Helium leakage is just another, new factor to add to all the other wear factors that drives are subject to.
50 kilometers above the surface the temperature and pressure are earth-normal. Huge dirigibles using oxygen and nitrogen would float in the denser co2 atmosphere.
Tell me, what's the wind like 50 km above Venus? Because anything over 15 m/s or so is hell on airships on earth.
"Civil discourse" does not mean that you are afraid to say things that some random reader might take offense from. You are thinking of "political correctness".
"Civil discourse" implies not gratuitously and unneccessarily insulting the addressee. That need not be boring, but it requires some thought in order to be engaging. There is some real wisdom in a movie called "Blast From the Past (1999)". My favorite quote is:
Troy - 'I know, I mean I thought a "gentleman" was somebody that owned horses. But it turns out, his short and simple definition of a lady or a gentleman is, someone who always tries to make sure the people around him or her are as comfortable as possible.'
Sometimes insult is warranted. Wisdom is knowing when that sometimes is. I wish I were wiser.
Just require that every atomic plant owner makes an insurance, for which you require that they have proper securities.
Fine; you've loaded the cost onto the ratepayers, which is just about everyone, so that's not unreasonable, but you have also made some low-life parasitic scum in an insurance company rich as lords, which there is no need or excuse to do.
Let the society as a whole "insure" the plant owners against catastrophes, as they largely do now. Then it's still the same "everyone" paying the cost, but you've eliminated the parasites.
But I would complete the rationalization. I would make society as a whole the builders and operators of the plants. Then you've eliminated more parasites, and profit motives would never intrude into the operation and create lackadaisical, corner-cutting practices.
There is a report by russia today [rt.com] that fukushima has cost $105 bn. Greenpeace (which hates nuclear power) claims a damage of $205 bn [greenpeace.org]. So, the range of nuclear meltdown damages is in the range of hundreds of billions of dollars. Now, the insurance company munich re reports [munichre.com] that they had to pay $31bn in 2014. I really think that it is doable to scale their business. So basically, there is one nuclear incident every 20 years world-wide. Lets be generous and say it costs around $400 bn. Now, the nuclear industry would have to pay $20 bn every year for such an insurance, world-wide. With a number of 438 reactors [euronuclear.org], that's $44 million per year. Energy companies make much much more with nuclear power on reactors in average than this amount, don't you think?
Great research and figuring, but with respect, I don't think the conclusion is warranted. One nuclear incident neatly packaged into a periodicity of 20 years is only an idealization.
What if chance does not smile, and you just happen to have three of those $400 billion catastrophes happen in one year. Or even one of them, but not 20 years after you begin your project, when you have accumulated all the take to pay for it. What if it happens the first year of your plan, when you have practically no take accumulated to pay for it.
I am strongly disposed to think that liability against catastrophes this mind-numbingly severe (also mega-hurricanes, devastating earthquakes, etc) is only feasable to be remedied by society as a whole - a.k.a., the government. As it always has been.
It is society as a whole which requires reliable and plentiful power; let it be society which insures against the catastrophes. In exchange, society gets to set engineering and operating rules. Maybe society in the form of an "operating priesthood", a governmental operating entity like the French have had such success with, should run such a critical industry. It would be imbued with the highest order of training, professionalism, and selfless excellence, and completely isolated from any influence of profit motive whatsoever.
If this offends the religious faith in free enterprise, we need to adapt and open our minds. After all, nobody denies that SOME THINGS only governments can do justice to. Is this not one of those things?
I hope the governments of Australia and especially the UK take note.
The government of the UK is so primitive they don't even have a written constitution limiting their power. They still have a sovereign monarch, for god's sake. The monarch is head of state and commander in chief. The limitations on the power of the monarch consist nothing more than gentlemen's agreements and ordinary laws and procedural rules which could be changed at any time.
Calling it a "constitutional monarchy" is an absurd lie, since there is no constitution.
Dog-cow is the idiot. Math challenged. An OLED bit that is off has literally zero luminance. The same way a 60 watt light bulb with zero current flowing through it has zero luminance. The ratio of an on bit to an off bit is then literally infinite. Infinite in the true mathematical sense.
You can't get that in an LCD due to basic physical reality. Physically realizable LCDs can never block that backlight 100.0%.
By the way, Russia has a long history of violating the airspace of other nations.
Ha. The USA made a wholesale business of such violations against the USSR with virtually no retaliation in kind. This little-known secret campaign began in 1946. There were losses, killed and imprisoned, kept secret. B-29s and Lockheed P2Vs were used; later C-130s and B-66s. By the 1950s, B-47 bombers were being repeatedly sent on deep penetration reconnaissance missions. Then came the U-2s. Francis Gary Powers' ill-fated spy flight was far from the only such.
All told more than 40 US aircraft invading Soviet aircraft were shot down. Question: can you identify a single Soviet or Russian aircraft which was ever shot down over US territory? As far as I know they have never violated it; certainly not systematically and purposefully.
Incidents of Russian aircraft probing the US which are drummed up as provocative are no more than Russians exercising their perfect right to range in international airspace "near" (gasp) to US territory.
Bullshit. The western friendly Turkey as reformed by Ataturk is long gone. Erdogan's Turkey of today is being lurched back in the medeival Islamist totalitarian direction, and mark well that he was popularly elected. Turkey now sees everything through Moslem colored glasses. It has no problem with ISIS at all.
You are right that Turkey hates Kurds with a vengeance.
Heck, the whole program should have been re-written in modern-style C++ 10 years ago.
There WAS no modern C++ until 2011. If you don't believe that, just consider that the (only) official smart pointer was the hideous monstrosity of std::auto_ptr until std::shared_ptr, std::unique_ptr, and std::weak_ptr supplanted it in c++11. OK, you could have used boost:shared_ptr 10 years ago, which is what I did, but you can't assume that all projects would be allowed to do so.
Android has come with emojis as a system resource since 4.1
My phone has been stuck on 4.0.4 for years and will be stuck there forever, you insensitive so-and-so. Android - ya want a new windshield wiper, ya gotta buy a new model car.
Maybe if Snowden had not have destroyed the intelligence relationship between the US and the European governments, the Isis attack could have been prevented.
So why do the corporations pay taxes to government if they control it?
Are you serious? It's the best money they spend. And they throw more on top of the taxes. Lobbying/bribes. The corpsters have locked up the best servants money can buy.
If you could articulate WHY you demand that it not be part of a DE, it would be helpful.

How is Netanyahu aligning closely with only the right wing of the Republican Party? Serious question.
He isn't. The President of the US, the country which in fairly recent history has been Israel's only real ally, has gone in the tank with a raging insane theocracy, Israel's (and the US's) sworn, naked, and unabashed enemy, and one of the most evil hotbeds of hate in the world. In so doing he has closely allied himself with the goal of the destruction of Israel (and the US). The only part the right wing of the Republican Party has with this is that they are the only ones expressing shock, disgust, and horror at this literal insanity, though they haven't done so with much intensity or dedication.
Perhaps your recollection isn't very good at all, because OS/2 2.0+'s user interface with the object-oriented Workplace Shell was a triumph, with superlative user and programming documentation. I can't think of anything modern that betters or even equals it. OS X? Not even close. Windows XP, 7, 8, 10? Bah. GNOME? Sorry Charlie.
