Interesting point. What if the weapon didn't impart energy, but rather USED the energy contained within the material itself to do the damage?
See? The Casimir effect is not widely known, but it does govern the interactions between molecules in a "conducting, non-ionic solid" a.k.a. "a metal". It says that there is an attraction that works on a micrometer level that pulls the molecules of a metal together.
From a materials science point of view, this answers the question as to why metals are so much denser than other materials. The molecules of the metal are attracted to one another more than the molecules of non-metals are attracted to each other.
This attraction between molecules of a non-ionic, conducting solid is highly sensitive to changes in the electromagnetic field. You have already experienced one aspect of this phenomenon, knowing that metals conduct electricity better than non-metals. Has anyone ever asked the question as to why metals are denser than non-metals? Maybe, maybe not. The answer is self evident that "something" keeps the molecules of a metal together compared to the molecules of, say, a gas or a liquid or even a solid like graphite. Graphite isn't strongly held together, even though it is a solid. Does carbon conduct electricity efficiently? No. There you go. Carbon isn't one of those molecules that the Casimir effect is talking about. It doesn't conduct electricity. It's not that dense.
Add this to Judy Wood's detailing of the variations of the magnetosphere and other evidence of energy weapons, it makes sense. Something altered the electromagnetic field around the WTC, causing the molecules of steel to repel each other, and the molecules came apart at normal temperatures, resulting in different types of metallic foam.
Some of the foam was aerosolized, and it went up into the atmosphere or people breathed it. Some of it wasn't quite so finely disassociated, and came down in dusty clumps and filled the neighborhood nooks and crannies. I found one of these nooks and collected the dust. It was years later, but I found it!
