CHRONOLOGY• 1883 Tesla invents an induction motor • 1884 Arrives penniless in the United States • 1885 Westinghouse Electric buys the rights to Tesla’s alternating current inventions • 1891 Invents the ‘Tesla coil’ • c. 1899 Discovers terrestrial stationary waves • 1917 Tesla receives the Edison MedalF ew contemporaries of Thomas Edison (1847–1931) took him on and won, but a man who could make such a claim was one of the great American inventor’s own former employees. Nikola Tesla, an eccentric electrical engineer, born in modern day Croatia but an emigrant to the U.S in 1884, was given work by Edison when he first landed in his new country. Contrasting personalities and conflicting ideas about electricity made the relationship a short one, sparking a bitter feud which would ultimately change the way the world received much of its power.A WAY TO TRANSPORT ELECTRICITY
The story begins earlier, though, back in Europe. The brilliant, eccentric and often troubled mind of Tesla was apparent from a young age. Although he did not come from an academic family background, there was a history of inventors in his ancestry and his father worked hard on developing Tesla’s mental abilities. Despite interruptions to his childhood education due to frequent sickness and the severe trauma caused by the death of his older brother, Dane, Tesla progressed into higher education, taking up a place at the university of Graz in Austria.The idea of the transmission of electricity without wires became a later interest for TeslaWhilst at the university, Tesla was exposed to demonstrations of existing generators and electric motors and began to ponder better ways of creating and transporting electricity. He later came up with an idea involving a rotating magnetic field in an induction motor which would generate an ‘alternating current’ (now known as a.c.). Most electricity being created at the time for use in homes, offices and factories involved a direct current (d.c.) which had its limitations, particularly the cost of generating it, its difficulty in being transported over long distances and its need for a commutator. By contrast, Tesla would later prove his alternating current could travel safely, efficiently and cheaply over long distances. His invention of an induction motor, in line with his earlier ideas in 1883 was the first big step on that road. His next move was to sell it.

For example, a Russian-French Scientist, Georges Lakhovsky, produced a version called the multi-wave oscillator. In this device a suitably charged tunable Tesla coil provided high-frequency input to a sort of antenna, which could then be passed over the afflicted area of a patient as part of the treatment process. Lakhovsky published a few books and articles in which he claims to have even treated cancer using a Tesla coil–based electrotherapy machine. 64 Of late, such therapy has been making a comeback of sorts, especially in the area of sports medicine—particularly in the form of a hand-held device called the violet ray machine. 65 Tesla and the Quest for Global Wireless Communications and Power Transmission The Wardenclyffe Project Tesla returned from Colorado Springs with only minimal success but clearly having spent most of the money invested by Astor. Tesla desperately needed another investor to work on his dream project, that of developing a global wireless communications and power transmission system, somehow using the properties of the Earth. Tesla wrote an article in Century magazine postulating not only the possibility of harnessing the Sun’s energy but also that it would be possible to wirelessly transmit communication signals as well as electrical power. Further, he wrote, it would be possible to control weather by the use of electrical energy and also that it would be possible to design the ultimate weapon systems that would put an end to any future wars. 66 One of those who read the article in Century was the famous banker and financier JP Morgan (see also the earlier section ‘Tesla and Radio/Telegraphy/Internet’)
