I'm sorry, but you don't appear to be analysing this in any sort of objective manner.
Your opening premise is that steel is not susceptible to fire induced failure based on a comparison with an unloaded mild steel mesh in a kerosene fire. You specifically advise that a reduction in strength "seems implausable".
However you now acknowledge that fire can indeed weaken steel. What I must stress to you, however, is that the material I presented quite specifically shows that it weakens it sufficiently under normal fire loadings to induce structural failure. The building codes which I then linked to showed unoquivically that there is a need to incorporate fire protection in order to address this.
You seek, however, to move the goalposts - twice.
Firstly, you claim that the fires are several orders of magnitude less than those which occurred on 1975. This misrepresents the situation. In actual fire, the fire was comparatively modest and although it extended to the 9th and 14th floors, it did not cover a significant proportion of the overall floorplate - in particular it affected in a utility duct. Contemporary reports indicate that areas at the furthest extent of the fire were extinguished almost immediately and the original fire was put out in a few hours. Most importantly, fire protection to the structural steel work was in-situ.
This in no way compares with a floorplate-wide fire over several stories including impact damage which dislodged structural fireproofing. To suggest otherwise indicates either a staggering failure to compare the two events or a dogged determination to compare apples with oranges in support of an unsubstantiated hypothesis.
The second shifting of the posts regards the "conversion" of the structural steelwork into "dust". This is patently ludicrous; the images already posted on this site by many, many others - including Truthers - show quite clearly that massive quantities of structural steelwork (generally heavily deformed, as one would expect in a collapse event) were found on-site following the collapse. To argue this point is, frankly, ludicrous.
I will leave the issue you seem to be raising, specifically speculation regarding the use of high-technology directed energy weapons or electrical charges, to others. But - and let's be quite specific on this - you admit that you have absolutely no evidence that such weapons exist. And on that basis, you may as well suggest that it was all Van Rijn's Invisible Elf.
