Wow all this comment about something I never cared about.
You're confused, aren't you?
Keep going kid. Want another tube of butt cream? You're gonna run out soon.
Absolutely it did. I was in the EOC one afternoon, doing an inspection, or something, and recall seeing a closet about the size of my living room, full of UPS supplies.
I will research it a little more, and see if I can come up with some exacts. I know one of the people who worked in the EOC back then, so I will drop him a line.
Cheers!
Cool, thanks! Were you at the old Building 7 EOC pre 9/11, or the new one?
Before answering further, please consider the possibility that information about the specific current capabilities and equipment of the EOC might be sensitive. (You would know that better than I do.)

NOTHING conducts heat 'immediatly'. YOUR premise here would fly in the face of the fire engineering principle of putting insulation on structiral steel in the first place.Java, their basic premise that fires, jet fuel/kerosene or office could be hot enough and of one location long enough weaken huge steel beams that would immediately conduct/disperse the heat throughout the entire length of itself(the beam) is insane.
Wow, just wow,, you looking for a stundie?Their subsequent premise that damage, weakening of steel beams, to a very limited area of the buildings could cause a building destroy itself by global collapse is even more insane. More insane because they have been grandiosely dubbed as gravity collapses which had heretofore been the domain of collapsed stars and the birth of the universe.
I thought I'd show everyone how hot a flame must be to cut steel. White/blue hot.
It is also very likely, though I don't have absolute proof, that the Emergency Operations Center in Building 7 would have used battery backup systems in quantity.
The current EOC, described here, is basically a hundred computer workstations tied in with communications networks. The 2001 version was probably not as elegantly laid out (probably more like traditional office desks, maybe cubicles) but still had the same basic functions and needs. We know the EOC was still receiving calls (and therefore, still powered up to be able to receive calls) after the mains power went down, so it must have had backup power of some kind. It's highly likely there was a backup generator, but the last thing an emergency operations center (intended to deal with, among other possible emergencies, widespread blackouts) would want is all the computers crashing just as the power fails during the few seconds it takes a backup generator to kick in. Or for them to be damaged by power surges just when they're about to be needed. So UPSs for the equipment are a necessity, either a large bank (what they probably have now) or just an individual one at each desk (what they probably had then), doesn't matter because you have about 200 liters of H2SO4 on hand either way.

Confused? Really? Why do you think that?
Also any reasonably sized company these days has three or four servers per office, all with UPS (If they've got any sense). Multiply that by the number of companies housed in a building that size. That's a lot of sulphuric acid lying around waiting to be liberated from it's plastic containers.
Nobody answered my question. How does a subject this stupid get 5 posts an hour for a whole month? I suspect botting.

Both. There is no contradiction between what I wrote and the passage you quoted. NIST and I agree that an unprotected chunk of steel that happens to be lying around in the office space could easily have reached a temperature of 800º to 1000º C.That's before we take into account the fact that your estimates are for the temperature of the fire, not the temperature of the steel. The WTC towers would have collapsed long before the temperature of the structural steel could reach 800º, because steel loses about 80% of its yield strength by 600º.
That is in disagreement with NIST:
"In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, Figure 6-36).
However, when bare steel reaches temperatures of 1,000 degrees Celsius, it softens and its strength reduces to roughly 10 percent of its room temperature value. Steel that is unprotected (e.g., if the fireproofing is dislodged) can reach the air temperature within the time period that the fires burned within the towers. Thus, yielding and buckling of the steel members (floor trusses, beams, and both core and exterior columns) with missing fireproofing were expected under the fire intensity and duration determined by NIST for the WTC towers.
"
They seem to claim that unprotected steel could very easily reach 1000º (room temperature). So who is correct? You or NIST? Please clarify.
Thanks, Sunstealer.Oh man that is priceless. Infact iirc a truther did do the calculations, there's a paper somwhere - I've quoted it before because the calculations are correct.
This one isn't the original but the calculations are included. Ignore all the rubbish and just look at page 8, fig 3 and page 10 for calculations - remember this is theoretical and not real world so there will be heat losses and not all reactants will react etc. http://www.journalof911studies.com/volume/200704/JLobdillThermiteChemistryWTC.pdf Max is 2Kg of steel melted per Kg of thermite, however, that is never going to be reached - see graph. In the real world a 1:1 ratio is more likely.
Yes, the old one, pre-911. It really was an incredible place!
And yes, there are some things that I cannot discuss about the EOC, unless you have the NWO TS Clearance card.
I think I do have one of those, because every time I tell my NWO handler I need information, she says "TS!"
A dedicated UPS room -- not just e.g. a cabinet between every pair of desks -- certainly makes sense for any EOC. (Above all, an EOC is a facility where "the lights stay on" regardless of what happens elsewhere. Backup generators would be the main system, but a large ups can cover for hours while generators are under maintenance or repairs, as well as helping deal with surges, transients, switching loads and other short-term issues.) And that raises the ante as far as available quantities and local concentrations of reactive sulfur compounds are concerned.

OK, I must curse you all now.
Let's recap:
- First you ignored specific heat and the distinction between moles and kilograms.
- Then you ignored the difference in units between specific heat and heat of fusion so you could claim that the latter is "540 times larger".
- Then, after I had again pointed out that the specific heat requires as much energy as the heat of fusion even under your own impossible assumptions, you quote a passage in which NIST makes the same point I had made and pretend that salvages your argument.
Simply put, to ask that question you have to admit that Harrit's thermitic material was found. Do you accept that?
NIST and I also agree that load-bearing structural steel would have failed long before it could have reached those temperatures. NIST gave a temperature at which steel would have lost 90% of its strength. I gave a temperature at which steel would have lost 80% of its yield strength. There's no contradiction between our numbers.
It doesn't matter if I accept that.
Oh yes it does. To challenge the presence of sulfur with that point would be acceptance of thermite in the area. The whole discussion would be over before it even started and you would thus be supporting the existence of a conspiracy to bring down the towers.
