He emigrated in 1884 to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company eventually marketed. -
Tesla's Magnifying Transmitter Principles of Working
School of Electrical Engineering University of Belgrade Tesla's magnifying transmitter principles of working Dr Jovan Cvetić, full prof. School of Electrical Engineering Belgrade, Serbia [email protected] School of Electrical Engineering University of Belgrade Contens The development of the HF, HV generators with oscilatory (LC) circuits: I - Tesla transformer (two weakly coupled LC circuits, the energy of a single charge in the primary capacitor transforms in the energy stored in the capacitance of the secondary, used by Tesla before 1891). It generates the damped oscillations. Since the coils are treated as the lumped elements the condition that the length of the wire of the secondary coil = quarter the wave length has a small impact on the magnitude of the induced voltage on the secondary. Using this method the maximum secondary voltage reaches about 10 MV with the frequency smaller than 50 kHz. II – The transformer with an extra coil (Magnifying transformer, Colorado Springs, 1899/1900). The extra coil is treated as a wave guide. Therefore the condition that the length of the wire of the secondary coil = quarter the wave length (or a little less) is necessary for the correct functioning of the coil. The purpose of using the extra coil is the generation of continuous harmonic oscillations of the great magnitude (theoretically infinite if there are no losses). The energy of many single charges in the primary capacitor are synchronously transferred to the extra coil enlarging the magnitude of the oscillations of the stationary wave in the coil. The maximum voltage is limited only by the breakdown voltage of the insulation on the top of the extra coil and by its dimensions. -

Wireless Power Transmission
IOSR Journal of Electrical and Electronics Engineering (IOSR-JEEE) e-ISSN: 2278-1676,p-ISSN: 2320-3331, Volume 9, Issue 3 Ver. II (May – Jun. 2014), PP 01-05 www.iosrjournals.org Wireless Power Transmission 1Sudha Bhutada(Senior Lect.), 2Punit Maheshwari(R&D Eng.) 1EE Dept.SV Polytechnic College Bhopal, India 2VLSI Dept. Navigator Technologies Bhopal, India Abstract: The concept of wireless power transmission method is as old as we are using electricity. N. Tesla the father of wireless power transmission was the first to give an idea of wireless power transmission and he was keenly interested in lightning the world without using wires (WPT).Since then series of experiments were made to make feasible transmission of power where it is not possible and commercially viable by advances, inventions in electronic devices in this field. In this paper we present the concept of wireless power transmission from one place in turn to another. This concept is mainly used for reducing the transmission and distribution losses. This in turn reduces the cost of transmission and distribution and also the cost of electrical energy for the consumers. In this paper we discussed the methods, recent developments in WPT, its merits, demerits and applications. Keywords: Wireless Power Transmission WPT, Radio Frequency RF I. Introduction We know our present system of overhead transmission and distribution has biggest disadvantage is percentage of power loss is around 26 to 28 % during transmission and distribution which is because of resistance of wires of grid. WRI (World resources Institute) says that India's electricity grid has highest T&D losses in the world around 27%. -

Muntz, Earl 1932
Earl “Madman” Muntz Biography Earl “Madman” Muntz - Class of 1932 (did not actually graduate), - b. January 3, 1914 d. June 21, 1987 Earl “Madman” Muntz! The very name conjures up memories, for many, of one of the wildest and craziest entrepreneurs of the 20th century. First of the loud, nuts, in-your-face used car salesmen, in the 1940s his billboards blanketed Southern California screaming, “I wanna give ‘em away, but Mrs. Muntz won’t let me - SHE’S CRAZY!” and “I buy ‘em retail, sell ‘em wholesale - IT'S MORE FUN THAT WAY!” These billboards, plus a steady bombardment of radio ads, helped Muntz sell $76 million worth of automobiles in 1947, when a million dollars was real money. And his logo -- a caricature of Muntz wearing a black Napoleon hat and red BVDs -- seemed to be everywhere. He produced and sold Muntz TVs, cheap but functional sets that competed successfully in the marketplace with RCA, Philco and other electronic giants of the time. And his TV business made him a second multimillion dollar fortune. He produced the first American sports car -- the Muntz Jet. A beautiful, well-crafted, speedy car that was a precursor of Chevrolet's Corvette, the Muntz Jet was an aesthetic and mechanical success, but Muntz’s first financial disappointment. The Jets sold for $5,500 but they cost $6,500 to produce, and this at a time (the early 1950s) when a new Cadillac could be had for $3,200. Earl Muntz’s third fortune came in the 1960s when he invented the four-track car stereo, becoming the first major player in the soon-to-be-huge car stereo market. -

The Fight to Preserve Tesla's Wardenclyffe Laboratory
The Fight to Preserve Tesla’s Wardenclyffe Laboratory Marianne Macy Excerpt from Margaret Cheney’s Tesla: Man Out of Time (Barnes and Noble Books, 1981, pp. 173-175) The world system for broadcasting—a concept designed to incorporate almost every aspect of modern communications—was all over but the mourning. Yet as long as the tower stood, Tesla continued his efforts to complete it. Exactly when all the workers left, no one could say. Thomas R. Bayles, the general passenger agent of the railroad station just across the road from the abandoned plant, only noticed that passengers had stopped getting off there. A caretaker remained on duty for a time. When curi- ous journalists or research engineers showed up they were allowed to climb to the tower top with the sweeping view of Long Island Sound. For all that the tower looked so light, it was built entirely without metal, even down to the wooden pegs holding together the wooden uprights and cross members. After abandoning the plan for covering the dome with a copper sheathing, Tesla had installed a removable disk through which a beam of radiation could be projected to the zenith. The visitors found the laboratory filled with curiously complex apparatus. In addition to much glass-blowing equipment there were a com- plex machine shop with eight lathes, X-ray devices, a great variety of high-frequency Tesla coils, one of his original radio-controlled robot boats and exhibit cases filled with thousands of bulbs and tubes. There were an office, library, instrument room, electrical generators and transform- ers, and great stocks of wire and cable. -

Abstract Over the Past Few Decades, the Methods of Electrical Generation
Abstract Over the past few decades, the methods of electrical generation such as by coal, nuclear fission, solar, wind, and geothermal have been studied and tested repeatedly, yet the mode of electrical transmission has remained the same: An electric grid of wires. However, at the turn of the 20th century, inventor and electrical pioneer Nikola Tesla attempted to build the Wardenclyffe Tower, a giant Tesla coil which he claimed could transmit power over large distances using induction. Unfortunately, funding for his research dried up and his claims have been dismissed. If Tesla's claims are true, the land and resource-consuming power grid can be eliminated. The magnitude of Tesla's vision was not something we attempted to test physically; rather, we intended to apply the results of small-scale transmission from a Tesla coil to the large scale to measure its feasibility. For our tests, we built a Tesla coil and measured its power usage. Next, we measured the power of a fluorescent light bulb and the distance from the coil at which it glowed. Finally, we compared the power and costs of our Tesla coil to that of North Anna's nuclear facilities, which we used as an example power station. Our results matched that of previous studies - the power output from a Tesla coil decreases dramatically with distance and thus would not be feasible as an efficient power transmitter. Although further research is needed on wireless effects on the large scale, the current electric grid remains the most efficient power transmission. Question In the late 19th century, Edison’s mode of electrical transfer using wires, won out over Tesla’s dream of wireless electricity.
