I've heard of the underwater sonic fences that the military is looking into - when a intruding diver is spotted, a sonic wave is sent out that "peaks" after a certain distance (when it reaches a certain frequency), and anybody that is in the peaking zone will become sick (vomiting) or even die, depending on the power used. My question is, could this technology be tweaked to actually create a fence of superenergized air molecules by adjusting the frequency to something that energizes air molecules within the peaking zone? I realize that "air" is imprecise, but you get the gist of it. Am I not being clear? Please ask me to clarify if you need to. Could this work, and why/why not?
