Nikola Tesla Books
IN SEARCH OF NIKOLA TESLA sure I had left no electrical stone unturned. The reaction was unanimous; even if the Tesla magnifying transmitter could generate the high voltages its inventor claimed, the device could never broadcast power with even the crudest efficiency. One electrical engineer I met produced figures based on the United States' 'Project Sanguine' (broadcasting very low-frequency signals to submarines). Even with the gigantic antenna the project required, its efficiency would be quite low. His figures seemed persuasive yet I was reminded of Tesla's claim that his own system of broadcasting differed from Marconi's, and Janischewski's remark that, when it came to radio, a Tesla magnifying transmitter might be far more efficient than a conventional system. When it came to Tesla's claim that his transmitted signals returned with increased strength and that he had tapped into an inexhaustible source of power my colleagues gave me amused looks of derision. I had to agree, the problem with 'cosmic power' was that I had no clear idea of what this 'inexhaustible source' represented. Nowhere in his writings, as far as I could discover, did Tesla take the time to spell out how this power operated or where it came from. Was it the voltage generated between the earth and upper atmosphere, I wondered? Did it originate in outer space? Tesla was being his usual elusive self. One important document remained to be studied. The theory proposed by Andrija Puharich to account for Tesla's transmission. Possibly this paper would supply the clues I had been seeking. As I read 'The Physics of the Tesla Magnifying Transmitter and the Transmission of Electrical Power Without Wires', I realized that Puharich had pulled out all his scientific stops. He argued that the secret of Tesla power transmission lay in the very high voltages which were generated in the coil. He wrote of âadvanced signals', 'de Broglie's phase waves' and through their invocation devised a theory for guided power transmission. In essence Puharich argued that the transmitter operated with two different kinds of electromagnetic radiation, 'retarded potentials' and 'advanced potentials'. The retarded, as he correctly pointed out, is associated with conventional broadcasting and consists of electromagnetic waves spreading out from the transmitter at the speed of light. 93
