Nikola Tesla. On His Work With Alternating Currents and Their Application to Wireless Telegraphy

This is the transcript of an extended three day interview of Nikola Tesla conducted by his legal counsel in 1916 in preparation for expert testimony in impending radio patent cases. In an account never intended for publication, Tesla describes his pioneering investigations into the nature of alternating currents as applied to wireless transmission. In a style uniquely his own, he carefully traces his work from the first high frequency alternators constructed at his Grand Street laboratory in New York City, and their associated tuned circuits through the establishment of his huge broadcasting facility, the mighty Wardenclyffe Plant, located 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 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.
