I became interested in Nikola Tesla several years ago, in 1970, while working on a large Tesla coil with some friends. I had heard that the Tesla coil was invented in an early attempt to transmit power by radio, but this was dismissed as the futile experiment of some-turn-of-the-century...
This apparatus is shown in the accompanying diagram where A is a coil, generally of many turns and of a very large diameter, wound in spiral form, either around a magnetic core or not as may be desired. C is a second coil formed by a conductor of much larger size and smaller length,...
Tesla had invented a powerful coil capable of generating high voltages and frequencies, leading to new forms of light, such as neon and fluorescent, as well as X-rays. Tesla also discovered that these coils, soon to be called “Tesla coils,” made it possible ...
Tesla apparently failed in his effort to show the identity of mass and energy. Apparently he understood that when speed increases, mass must decrease. He seems to have thought that mass might be "converted" to energy and vice versa, rather than that they were identical in some way, as is ...
where the resistance of the coil is zero and where the Q of the circuit is infinite. If our antenna plate were connected to the resonant "secondary" of a superconductive Tesla coil, we might in fact see the output voltage grow to the megavolt range. However, in most real-world tuned ci...
Tesla could also be sarcastic: "The greatest men of science have told me [the Tesla coil] was my best achievement. . . . For instance, a man fills this space with hydrogen; he employs all my instrumentalities, everything that is necessary, but calls it a new wireless system—I cannot...

IV. The Discovery of the Tesla Coil and Transformer V. The Magnifying Transmitter VI. The Art of Telautomatics I. My Early Life The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain. Its ultimate purpose is the complete ...
” And there in the park, with a stick, Tesla drew a crude diagram in the dirt: a motor using the principle of rotating magnetic fields created by two or more alternating currents. While AC electrification had been employed before, there would never be a practical, working motor run on ...
