I've mentioned Tesla's pocket "quake" machine in a few posts and thought of opening a thread on it, so glad to see you got farther than I did with it.There's no question Tesla's ideas on frequency and harmonics can produce destructive results--it's a fascinating area of science that leads in several directions, one being scalar weapons and HAARP arrays. Focused energy at a distance. Also to his little quake gadget at the other end of the spectrum.Tom Beardon is the best-known proponent about all this; he believes the Soviets had scalar arrays operational in the 70s and the US caught up more recently--and he also claims there are rogue non-state actors with them, FWIW. But the little that is known about the subject and his claims for a remarkable black arsenal of "Tesla tech" gives one pause; some of it is really out there.One claim though was quite compelling: IIRC the Soviets were working on a Tesla idea for a resonant tube as a weapon (the story goes that Stalin had Soviet scientists go back through scientific literature into the late 19th C to see if there was anything they could develop to leapfrog the US, and they came upon Telsa and experimented extensively with his ideas and patents). The idea was to induce a resonant frequency in a large metal tube that would act like a harmonic cannon. They raised the frequency in steps until they reached a certain level of hz that began to make the field people violently ill. They abandoned experiments in that range because they realized that the focused resonance could actually kill people. A few more steps and you're in literal tin-foil hat territory, with those claims of the gov't bombarding people with "mind-control beams."You could see a scenario of literally vibrating the towers to pieces, in tandem with thermite and shaped charges. Itexplain a lot: the pulverized concrete, the neatly sectioned core columns broken at the welds, the infamous seismic readings...but like insolubrious points out, it wouldn't be a version of the pocket quake machine but probably a scalar weapon, and here you're in an area as speculative as 4g mini-nukes unfortunately.[edit on 24-4-2008 by gottago]
