How did you determine the "energy concentration" of the nanothermite in the red layer?Nano-thermic paint is an utterly ridiculous idea for melting steel structure.
By thinly spreading out the incendiary material , there is insufficient energy
concentration to raise the temperature of the entire cross-section of steel
to anywhere near melting temperatures.
In any case, even if your claims are true, it's hardly consequential to anything. It would rule out one of basically endless possibilities of how the buildings might have been rigged with nanaothermite.
