In this recently discovered transcript of a three day interview conducted in 1916, Nikola Tesla, using words and graphic illustrations, provides a step by step description of his remarkable accomplishments in the area of radio frequency engineering. In a style uniquely his own, Tesla carefully traces his work - from the first high frequency alternators constructed at his New York City Grand Street laboratory and their associated tuned circuits through the establishment of his huge broadcasting facility, the Wardenclyffe Plant, at Shoreham, Long Island. Among the variety of topics discussed are: high frequency alternators, experiments with wireless telegraphy and telephony, mechanical and electrical oscillators, the Colorado experiments, theory and technique of energy transmission, the Long Island plant, and arrangements for receiving. Seldom, in technical research, has such a treasure of descriptive commentary and historical documentation been discovered. The previously untold story found within the pages of this remarkable book has been described by the prominent Tesla researcher James Corum as a "veritable Rosetta stone" for tracing the technical thoughts of one of our most distinguished engineering scientists. Includes 61 photos and 42 line-art illustrations, many never before published.
