they offer a massive review of the works by all the popular nuclear advocates. It's a very credible effort, though I don't find it completely persuasive. They don't consider the possibility of aneutronic fusion devices, and I don't feel they've completely explained the dust production, or the high temperature effects seen in the dust. On the other hand, I don't have much to offer in response to their explanations for the tritium levels found at ground zero, or their explanation of barium & strontium & other trace elements in the dust samples. AE911T also claim that all the early-responder cancers can be explained by toxic chemical effects; I don't have the expertise to say. The opposing argument (in Prager's work) seems to be based on anonymous sources.
Niels Harrit thought that the amount of thermite required to bring down the towers would've been in the hundreds of tons, but Derrick Grimmer's original work said 11 tons. With directed thermite shaped-charges such as discussed in the above video, the amount required might have been even less.
Overall, the case for any necessity of aneutronic cold fusion or some other exotic technology at the WTC on 9/11, is looking much weaker than before.
According to AE911T, there's nothing odd about the elements found. Of course they're being polemical in their presentation, I don't know whether all chemists would agree. I watched the first half of the "Architect's Guide Part 1" and I was uncomfortable that they were claiming to be presenting the material in a way that would be suitable for college credit and that would "leave the student to decide", and yet they also took a very strong rhetorical stand in favor of the controlled demolition hypothesis. Not that I see that the "fire & gravitational collapse" thesis is defensible. But surely if Gage wasn't willing to defend it, he could have found an NIST or Popular Mechanics spokesman who would have.
