the tesla longitudinal wave (george w. damm)
DESCRIPTION
George W. Damm suggests that Nikola Tesla incorporated acoustic resonant criteria in the design and modulation of his tower at Shoreham, Long Island. At first, this seems a bit farfetched, but a pause to check the dimensions of the tower’s components and their acoustic resonant frequencies reveals that they are well-matched to the earth’s electrical resonant frequencies. Tesla’s sensitivity to sound, vibration and light, and his early work with compressed air oscillator frequency control may have been combined in his last major project.When reading this report, do so with the physics of acoustic vibrations in mind; that is, ordinary sound waves in air. Sound waves are longitudinal in nature and propagate in the form of compression and rarefaction in a medium, at the speed of sound. The speed of sound in standard air is 340 meters/sec (1115 feet/sec). Nikola Tesla insisted his electrical transmissions were longitudinal in nature, and thus similar to sound waves. Whereas sound waves have compression (-) and rarefaction (+), electrical waves have positive and negative charge polarity.In order to show how Tesla may have incorporated actual acoustic vibration into the tower’s design, some descriptions and dimensions of the tower will be helpful.1 These are shown in Figure 1.By Tesla’s own testimony1, the tower was 187 feet tall from the ground to the top of the dome. The shaft into the ground was 10 x 12 feet square and 120 feet deep. The water table was reached at a depth of 80 feet. Other sources2 state that four smaller diameter shafts were bored below water level at the base of the main shaft, each with a length of 100 feet and perpendicular to each other. These provided an intimate electrical contact to the earth.Fig. 2 — Harmonics.Fig. 2 — Harmonics.The dome on top of the tower is given to have a diameter of 68 feet. The dome framework was constructed completely of steel. It sat on top of the tower truss structure which was made entirely of pine timbers and steel plates at the joints. A segmented steel pipe telescoped to extend up to 300 feet from the base of the underground shaft. There were about 16 telescoping sections. The variable heights were used to determine the nodal points for electrical vibrations. Tesla said he could measure any distance on earth with an accuracy of ± four feet, including the earth’s size.1For the dimensions of the tower given in Figure 1, it is possible to calculate various fundamental acoustic frequencies and their harmonics. Key dimensions of the tower are shown in Table 1.Dome diameter 68 ft 20.7 mTower height to dome top 187 ft 57.0 mTower height to mid-dome 153 ft 46.6 mShalt depth 120 ft 36.6 mTelescoping tube length up to 300 ft up to 91.5 mDepth to water table 80 ft 24.4 mTable 1 — Dimensions of Tesla’s tower. The acoustic resonant frequency and nodal points for pipes differ somewhat depending on whether the pipe is closed at both ends, has one end open, or is open at both ends. The manner in which this varies is shown in Figure 2.3Given the various dimensions (L) of the tower design and the velocity of sound (v = 340 m/sec = 1115 ft/sec), it is possible to calculate various acoustic fundamental and harmonic resonant frequencies. Upon doing this, it is evident that the air acoustic resonant frequencies of the tower fall in the same range as the earth electrical resonant frequencies. For example, the telescoping tube length (L) can be calculated for a couple of earth electrical resonant frequencies that have been mentioned on occasion. One resonant frequency mentioned is 7.5 Hz. The fundamental frequency (f1) is given by:TRANSCRIPT
