To get back to the questions Oystein ignored...
Oystein said:
No. You forgot to add the potential energy that gets converted to destruction eventually, to the tune of 3.6 meters of free fall every 3.6 meters - it doesn't matter by the way if free-fall actually happened. Every time your 100,000 tons worth of building structure drop 3.6 meters - and come to a full stop eventually, no matter what the effective acceleration, it all (mostly) gets converted to destruction.
Is it 3.6 m or is it 23.5?
Oystein said:
Nope, because (as Bazant's very first limiting case model showed) the actual load-bearing steel structure could never absorb the 3.6 meters worth of potential energy that get converted to destruction each time the top part drops another 3.6 meters, let alone absorb the kinetic energy already accumulated. That's why kinetic energy / speed increases floor by floor by floor.
[Leaving Bazant's erroneous and debunked model alone for now...]
1) You seem to be inventing energy sources here. There is only one mechanical energy source in your model: gravity. It is expressed either as potential energy (not yet converted to kinetic energy) or as kinetic energy. Kinetic energy in this case is expressed as the movement of mass downwards, as per gravity, and/or as the energy used in the destruction of intervening matter. When that kinetic energy from gravity is spent in destroying the intervening building structure, much of it is lost in heat, sound and deformation. You are also talking about pulverization into fine particles here. Considering the materials in the building, and the time frame we're talking about (i.e., not geological epochs) this requires an energy source beyond mere gravity.
2) Weren't the floors being pulverized
during these floor collisions? If not, when did things get pulverized? Remember, I am asking you to provide a
pulverization model here.
Oystein said:
Exactly. This has been accounted for. By Bazant (limiting case for deformation/buckling of steel structure) and Greening (adding pulverization). The energy thus dissipated per story is less than the potential energy differential released by the fall through the height of one story.
And that is why kinetic energy increases floor by floor by floor.
Again ignoring the supernaturally derived energy here, Greening I believe only discussed the energy required to pulverize concrete. And again, how does the kinetic energy increase when each floor is getting
pulverized in its collision with the next?
Oystein said:
No. If you slam thousands of tons of hard stuff on tiles, wallboard, concrete, fire-resistant foam, and do so repeatedly, your gonna crush much of that to crumbles and dust.
Most of the dust was from such materials.
And what happened to the "hard stuff"?
Oystein said:
It appears that you have never read Greenings papers on the topic of concrete comminuition in the WTC, or else you wouldn't write such ignorant nonsense.
Greening was discussing concrete only. What do you have to say about the comminution of heavy oak desks, marble slabs, metal filing cabinets, plumbing, couches, upholstered chairs, numerous heavy plastics such as chairs and desks, lamps, computers, photocopy machines, carpeting and other materials?
Oystein said:
On the contrary, yes, the particle-ization of all some of the buildings' contents, particularly concrete and gypsum, suggests exactly that. It has been shown that this is PRECISELY what must be expected from just that sort of collapse.
What
wasn't particle-ized? Do you have evidence of steel flooring, heavy oak desks, marble slabs, metal filing cabinets, plumbing, couches, upholstered chairs, numerous heavy plastics such as chairs and desks, lamps, computers, photocopy machines, carpeting, and, I'm sorry, but large human body parts?
Oystein said:
Why should such human shreds, particularly the smaller ones, not get ejected with the air that's pushed out the windows as the volume of air in a floor is reduced from over 14,000 cubic meters to nothing in a fraction of a second?
What we're really looking at here is how the bodies 1) got "shredded" in pancaking floor collapses, and 2) how pancaking floors would eject these contents if most of their own structure has also been particle-ized (in your model).
Oystein said:
Nothing obvious here: There were no audible detonations loud enough to be ascribed to explosive charges sufficient to sever structural steel.
Many reported audible explosive sounds. You also cannot say what detonations from the inner core of fully furnished buildings would sound like from half a kilometre up in the sky.
Can you?
Oystein said:
To all but the deluded fringe, the appearance of the towers was that of gravitational collapses.
Source? Most at the time commented how the "collapses" looked like implosions/controlled demolitions. Even Bazant claimed to speak for structural engineers when he commented that "few were expecting the towers to collapse" [paraphrase].
Oystein said:
Especially to the experts. Remember Danny Jowenko? What he thought about the twin towers and CD? You think you are smarter about the look of CDs than Danny Jowenko was?
To Danny Jowenko, it was obvious that the twin towers could not possibly have been explosive demolitions.
I'm not sure what Jowenko said about the towers. I wonder if his opinion was based more on the projected difficulty in bringing down such towers with such (relative) precision. Furthermore, we know he thought WTC7 was a classic implosion.
