ORD has (will have when construction is complete) 16 MW emergency generator capacity. That is backup. The way the place is wired, they just connected at the switchgears to everything, but with automatic switches to shed loads so as to not overlaod the generators.
Still, if one of those switchgears were to catch fire, the way one apparently did at Hartsfield, a large area would be without main power and without backup power, but it would be likely confined to a single terminal.
$20 million is an very low estimate,especially for construction at an airport with all the security requirements, the need to work around airport operations, the need to keep the place open 24 hrs a day / 365 days a year (366 on leap years), etc.
Yes, at another large airport I've done work at they have160,000 gallons of diesel fuel just for backup for the heating plant and emergency generators. That does not count the fuel stored for the trucks and buses, which the generators would not have access to, anyway.
I'm involved in an emergency generator construction project for an airport that was previously the world's busiest. They will have an 18 MW capacity. The system was designed to run for 4 hours from the diesel fuel tanks located in the generator building ( a code requirement) and for 48 hours including the underground diesel fuel storage tanks located at the heating and refrigeration plant. (a request from the user and insurer) A lot of things are connected to the generators, but they have a load shedding program to drop power to less essential items if there is too much draw. Those with the highest priority are fire suppression systems, emergency lighting, and air traffic safety (which I believe, has its' own backup). Lowest priority are items that the tenants want in order to stay in operation.
Sometimes one elevator in a bank is designated to be connected to emergency power. Sometimes, hydraulic elevators will make a non-powered return to the first floor upon losing electricity. I'm assuming a cable elevator can do similar.
It's not really all eggs in one basket. There are several other airports in the US with similar numbers of flights, and even Delta has other hubs,.like Salt Lake City, Minneapolis, Detroit, & NY, though its' headquarters and largest hub is Atlanta.
It changed back and forth a couple of years ago if you go by number of flights, but O'Hare lost its' No. 1 status way earlier than that if you go by number of passengers
No, he's opposed to it because the major corporations pushing it are assholes who will hide evidence about potential hazards to health and the environment if it might cost them a few dollars to admit.
We ride in cleaner safer cars, that show up on time, are easy to acquire, have drivers that speak the local language and we do all of this for less money.
That does not match the experiences I have had in Uber - except for the on time part. And "on time" hardly matters downtown, which is the only place I grab a taxi lately, and where there are always taxis around to hail.
Last Uber driver I had obviously spoke english as a second language, didn't know the route to take except how the GPS on his phone showed, (which was not a very good route, anyway) and then proceeded to go north instead of turning around because he apparently couldn't figure out that the phone was showing south without telling him to turn around.
Mike Flynn was fired for lying to Pence. If Pence was "in on it", Flynn wouldn't have lied, and Pence wouldn't have been asking.
You're assuming that the reason given for firing Flynn wasn't just an excuse. There's evidence that Pence, among others on the transition team that Pence was in charge of, knew about Flynn's activities before Flynn "lied to Pence".
Pence would be worse on social issues, but he would likely be better on foreign policy, and economic management.
You have to roll up your sleeves and make solar and wind so totally ridiculously cheaper than coal or natural gas that the bottom will fall out of the natural gas market . . .
Too late, the bottom has already fallen out of the natural gas market. Nobody's drilling new fracking sites at today's prices.
A better option is to mandate efficiency standards for buildings.
Too late, already done. California has had mandatory efficiency standards for buildings since at least the 1980s. Most building codes currently include energy efficiency standards, at least in the US. I believe there's a federal mandate for states to adopt an energy code in order to receive certain federal funds.
Cutler reckoned kernel mode code should enforce strict contracts like 'no page faults above dispatch level' and the kernel should BSOD if those were broken to force people to fix the bugs. From my experience of Windows 2000, XP and 7 machines - none of which have ever BSOD'd unless the hardware is failing or a driver was buggy - he was right.
XP used to bluescreen on me every once and a while until SP2 & 3. Then it became rarer, but still happened.
I can still bluescreen my Windows 7 laptop by using the trackpad instead of a mouse when in the login screen after booting, but I believe that is a known driver issue that HP refuses to fix.
Microsoft are in trouble because these compete with their failed Metro apps on Windows, and make Windows itself kind of irrelevant because now the browser is the OS and the cloud is the disk.
So Microsoft's 1990s paranoia about Netscape's attempt to make the browser the OS is finally proving true?
Nice try to change the subject with more fake news. FYI many of those that complaining the loudest about drone strikes are those complaining about Trump. The Republicans were the ones with the greatest support for drone strikes during both previous administrations. And the Trump administration hasn't quit killing people with Predator drones.
You misspelled misspelled.
And if it's a "fishing expedition" (it's not), Mueller at least knows where they're biting, as he's already gotten Guilty pleas.
Yes. You remember the Iraqi "asset" going by the code name "Curveball", and the information he provided about weapons of mass destruction, and how useful he was to our efforts at making the middle east more stable peaceful. This will work out just as well for our new paid informants.
there's no shortage of Americans calling Trump "racist" because he purposed a ban on Muslim immigration from certain countries, or because he wants to build a wall between the US and Mexico.
That's a false equivalency. It used to be true that both parties helped the rich donors while placating their voters, but they had core sets of values that they would more-or-less adhere to when push came to shove. There's a huge difference between Trump's "Republican" party and the old Republican and Democratic parties, and it's not and improvement to abandon all sense of truth and decency, eliminate as many checks and balances as possible, call reality "fake news", and lie so much and so blatantly that it almost becomes normalized..
An RFQ is typically a Request For Qualifications.
A "Request for Quote" would typically be an "RFP", as in a Request For Proposal.
Also, this is not something that can be "quoted", as they appear to be taking some sort of "Design-Build" approach.
Currently, Google maps lists the blue line as 39 minutes between O'Hare and Clark & Lake (downtown station closest to O'Hare). I've taken it many times, and you have to allow an hour, including walking to the station.
The blue line and red line already go under the Chicago River in a couple of places, and are undoubtedly under the water table for most of the time they're underground, so why should the water table be considered as so much of a problem for a new tunnel?

Correction: Six 3 MW generators for 18 MW capacity.

On those points I agree.

I believe that it's you who has misinterpreted the intent of the phrase "depress your opponent's supporters".
The federal and state governments are each considered sovereign, within their respective jurisdictions.

A 28 foot deep piling is not all that deep. A 28 feet deep tunnel won't even get safely below all the basements, foundations, & sewers.
