Only if your container of water is kept boiling will it have any hope of defrosting the contents of the freezer."

"I know this perfectly well, I was asking you a question as to the outcome. Well done, now you need to apply that logic to GZ."
So we both agree;
"Your freezer analogy shows an impressive ignorance of science."

"In my theory, we have an insulated hot space with a renewing heat source. If you have been following this thread, you'll note that I earlier explained how fresh dust would be exposed and gradually ignited due to excavation activity on the surface."
GlennB said:
"Oh dear, you did. An insulated space capable of reaching ~1500c where "excavation" is taking place - just above - in order to renew the heat source? Can you spot the problems with this theory? I lost count just thinking about it for a minute."
No. Initially after 9/11, excavation activity would have been many feet above.
Tom Manley of the Uniformed Firefighters Association:
As demolition and rescue crews toiled to clear the debris, air pockets would open up, allowing fresh oxygen to cause hot spots to flare up.
Evidence that the pocket was absent oxygen but maintained a combustible temperature or higher.
I would suggest that with nothing to totally block it, the dust containing thermitic material, continued to fall into these pockets which were easily hot enough to continually achieve ignition (430 C) and maintain high ambient temperatures.
During a fresh oxygen-fed flareup, these super-heated pockets would ignite every nearby combustible, where, if not high enough already, quite likely pushed temperatures to a point where metals melt or become red hot.
"You couldn't even begin to imagine how much water was pumped in there," said Tom Manley of the Uniformed Firefighters Association, the largest fire department union. "It was like you were creating a giant lake."
How do you account for such resistant, long lasting, incredibly hot fires, in an oxygen-starved environment Glenn if not for some sort of heat generating activity that provides its own oxygen?
GlennB said:
"Meanwhile, a previous question you have ducked - with this highly combustible dust everywhere, why wouldn't random ignition sources set it off?"
That question has been answered several times.
I would say that any time those thermitic red chips were exposed to a minimum temperature of 430 C, they would ignite.
We are talking chip sizes that would require at least a good magnifying glass to see, and require ignition temperatures of 430 C.
That is a far cry from the ~20 C and lower ambient daytime temperatures that existed at the surface.
Wherever temperatures reached 430 C or greater at the oxygen-rich surface, not only would the red chips in the dust ignite, but so would other combustible materials in the dust, like paper.

or describing a collapse, explained by real bona fides experts to have been caused by an unfought fire, as a controlled demolition in which you cannot even get the collapse time right.....or notice that there were no loud explosions, nor timers, nor shock cord nor cut beams........
