Well I appreciate you trying to answer my question. Even if there was some sort of microwave beam technology capable of causing vibrations in the building, this still wouldn't make them disappear. It would only make the pieces smaller, and they would still end up on the pile. So it wouldn't cause the pile to be smaller...just be made of smaller pieces. Most of the structure was made of steel, what could cause steel disappear?
I like to design things. Whenever I come up with an idea for something, I run it through a "feasibility test" in my mind, where I determine if it is even possible to do what I am think of. This involves me mentally walking through everything that I would have to do to build whatever it is that I'm designing. Something needs to be feasible to be possible. So far, I'm not seeing how it is feasible for 1000's of tons of debris to be missing from the pile.
