Too little energy?

See the title of this thread. A LOT of thermite. Enough to really soften up the entire 81st floor.
The "confused" smiley is appropriate here: You are confused about the context, and confused about how thermite is and isn't identified.
To clue you in: We were most recently discussing Jones' paper. triforcharity pointed out that the red chips in Jones' paper can't be thermite, since their energy yield, as shown in Jones' own paper, is too
high.
You are under the wrong impression that thermite contains or releases a lot of energy (per weight unit). It doesn't. The
maximum energy contained in thermite and released when burning can be precisely calculated, it is a little less than 4 kJ/g (kilo-Joules per gram - Joules being the SI unit for energy).
Two of the chips in Jones' paper released
more than 4kJ/g, in one peak. This is incontrovertible proof that whatever they burned there cannot
possibly be thermite.
You may wonder what these energetic substances might have been? I can't tell you, because the paper is pretty ****** and failed to analyse the big elephant in the room: The organic matrix that they found to be present, but went on to ignore.
Can an organic matrix be more energetic than thermite?
Yes.
Indeed, pretty much every organic compound is more energetic than thermite. Fuel, resins, wood, plastics, fats, solvents - they all contain and release MUCH more energy per mass than thermite. In fact, YOU, your own body, is (on average) more energetic than thermite, even with all the water you contain.
I mentioned resins particularly because that's what I suspect the organic matrix to be made of: the red chips are most likely a red paint with iron oxide as pigment, kaolinite as filler, and a resin to hold it all together.
