"Parasite oscillat s, or circuits, within tl main circult wore a source uanger from this cause. Fints of resistance in the main circuit. could result in minor os. llating circuits between terminals or between two points of resistance and these minor circuits would have a very much higher period of oscillation than the main circuit and could be set into oscillation by the main cùrrent of lower frequency. "Even when the principal oscillating circuit was adjusted for the greatest efficiency of operation by the dimination of all sources of losses the fire balls continued to occur but these were due to stray high frequency charges from random earth currents. "From these experiences it became apparent that the fire balls resulted from the interaction of two frequencies, a stray higher frequency wave imposed on the lower frequency free oscillation of the main circuit. "As the free oscillation of the circuit builds up from the zero point to the quarter wave length node it passes through various rates of change. In a current of shorter wavelength the rates of change will be stecper. When the two currents react on each other the resultant complex will contain a wave in which there is an extremely steep rate of change, and for the briefest instant currents may move at a tremendous rate, at the rate of millions of horsepower. ! "This condition acts as a trigger which may cause the total energy of the powerful longer wave to be discharged in an infinitesmally small interval of time and at a proportionately tremendously great rate of energy movement which cannot confine itself to the metal circuit and is released into surrounding space with inconceivable violence." It is but a step, from learning how a high frequency current can explosively discharge a lower frequency current, to using the principle to design a system in which these explosions can be produced by intont. The following process appears a possible one but no evidence is available that it is the one Tesla evolved: An oscillator, such as he used to send power wirelessly around the certh at Colorado Springs, is det in operation at a frequency to which a given warship is resonant. The complex structure of a ship would provide a great number of spots in which electrical oscillations will be set up of a much higher frequency than those coursing through the ship as a whole. Inese parasiste.currents will react on the main current causing the production of fireballs which by their explosions will destroy the ship, even more effectively than the explosion of the magazine which would also take place. A second oscillator may be used to transmit the shorter wavelength current. Somewhat later I learned the reason for Tesla's reticence to discuss details. This came shortly after Stanley Baldwin replaced Neville Chamberlin as Prime Minister of Great Britain. Tesla revealed that he had carried on negotiations with Prime Minister Chamberlin for the sale of his ray system to Great Britain for $30,000,000 on the basis of his presentation that the device would provide complete protection for the British Isles against any enemy approaching by sea or air, and would provide an 113
