Nikola Tesla's Earthquake Machine "...He constructed a simple device consisting of a piston suspended in a cylinder, which bypassed the necessity of a camshaft driven by a rotating power source, such as a gasoline or steam engine. In this way, he hoped to overcome loss of power through friction produced by the old system. This small device also enabled Tesla to try out his experiments in resonance. Every substance has a resonant frequency which is demonstrated by the principle of sympathetic vibration&endash;the most obvious example is the wine glass shattered by an opera singer (or a tape recording for you couch potatoes.) If this frequency is matched and amplified, any material may be literally shaken to pieces. A vibrating assembly with an adjustable frequency was finally perfected, and by 1897, Tesla was causing trouble with it in and near the neighborhood around his loft laboratory. Reporter A.L. Besnson wrote about this device in late 1911 or early 1912 for the Hearst tabloid The World Today. After fastening the resonator ("no larger than an alarm clock") to a steel bar (or "link") two feet long and two inches thick: He set the vibrator in "tune" with the link. For a long time nothing happened-&endash;vibrations of machine and link did not seem to coincide, but at last they did and the great steel began to tremble, increased its trembling until it dialated and contracted like a beating heart&endash;and finally broke. Sledge hammers could not have done it; crowbars could not have done it, but a fusillade of taps, no one of which would have harmed a baby, did it. Tesla was pleased...." "...One source has it that the device "bonded to the metal on an atomic level" and Tesla was unable to get at the controls, but it seems more likely that the wild movements of the girder, combined with the panic that he might bring the neigborhood down, moved Tesla to this unsubtle action. He later mused to reporters that the very earth could be split in two given the right conditions. The detonation of a ton of dynamite at intervals of one hour and forty-nine minutes would step up the natural standing wave that would be produced until the earth's crust could no longer contain the interior. He called his new science "tele-geodynamics." ..."
