"2000 PSI thermobarics" is a smokescreen. Conventional explosives routinely top 20,000 PSI -- but only at the surface of the explosive. This statistic is utterly meaningless. You need to consider area of effect, shock front, and pressure-impulse at the target. Most buildings, even concrete ones, are destroyed at only 15 PSI, but this number has absolutely nothing to do with your number.
No one is stopping you, pal. I give this exact advice frequently. Oddly, nobody in the Truth Movement ever seems to take it.
I don't recall you proposing a mechanism where "thermobarics" are a good fit to microsphere creation, so no, I don't think we are discussing it. I think you're off topic, along with previously debunked.
I would advise Gravy not to specially address thermobarics in his movie. His movie doesn't restrict itself to any class of explosives. Thermobarics offer no qualitative differences versus conventional explosives in this application. Power-to-weight, pressure amplitude, and wavefront are different. And they're more complex. That's all. The theory offers no meaningful advantage over any other, equally stupid explosives theory.
The thermite theory, pathetic as it is, at least offers the advantage of being quiet and not being seismically detectable. It fails in many other ways, of course, but at least it's different. Your thermobaric story is not.

Basically, the explosion of almost all types of Stun and Diversion / Distraction Grenades/Devices consists of the extremely rapid burning of a mixture of very finely powdered metal "fuel" and a potent oxidizer (which furnishes the necessary oxygen for the rapid combustion). For the technically inclined, the metal fuels are usually magnesium or aluminum and the oxidizers are either potassium perchlorate or a similar chemical with a high oxygen content.

In the normal functional range of true Stun Grenades, this over-pressure is relatively small, being on the order of ten psi or less. In fact, the most effective pressure operating range of a stun grenade is from five to ten psi.
I can't think of why the oxidizing agent used in stun grenades can't be a ferrous agent such as Fe3O4, which is comonly used in thermite. If your oxidizing agent for an aluminum powder explosion or deflagration is Fe304, then ferrous microspheres would be expected, correct? Then again, I'm no chemist, so maybe somebody that actually knows something about chemistry, like Apollo20, can tell us for sure if there is a physical principle which forbids this.
So, at the low end we can have 10 psi explosions. At the high end, from the Australian military web site document that I linked to previously, we saw a graph with a thermobaric of 1/2 the overpressure of a high explosive. The High Explosive overpressure you give is much higher than the reference I found for TNT. However, as I've tried to make clear, a WTC explosive device would have to be less explosive than a High Explosive, if for no other reason than that otherwise we would have seen a shock wave.
If you have some scientific reason for claiming that explosions with 20 psi, 200 psi, or 2000 psi can't be produced, while a low value of 10 psi but a high value of 4,000 - 20,000 psi can, why don't you let us know what that would be?
I don't think you will make such a claim (and even if you did, I wouldn't believe it, short of some totally unexpected proof), so the issue of thermobaric plausibility boils down to whether or not explosions can be concocted of sufficiently high psi (which will be a function of time and space, of course) to pulverize the contents of a WTC storey, but of sufficiently low velocity not to exceed observed 'squib' velocities.
You haven't written anything to make me dismiss this as a possibility. I will try and run this past a physics prof or two, but I think the guys I need to talk to are at mining colleges, or maybe somebody in a chemical engineering department that works on explosives. I'm auditing a graduate course in solid state physics, so I can certainly ask my own professor.
Oh, and I have indeed not only, in times past, talked to an applied a mathematician - my cousin, actually- I've also conducted a mini-survey of civil engineers to ask them if they studied the NIST report, and if they'd read Professor Jones' paper. Although my survey size was very small (6), as expected, they weren't paying much attention either to NIST or Professor Jones. I also urged other participants in the physorg 911 threads to take various papers on the WTC collapse to their local physics department - years ago. You're not the only one.
I had hoped that lots of serious physicists would post at physorg on 911, but aside from Apollo20, there's been very little in the way of Ph.D. level physicists. I can only think of Charles M. Beck.
