NIKOLA TESLA. Early career, he worked at Budapest Telephone Exchange, where he made many improvements to the Central Station equipment and claimed to have perfected, a telephone repeater and amplifier. He joined Continental Edison Company and began working for installation of citywide indoor lighting, using electric power utility.
He moved to Newyork, to join Edison Machine Works, in a manufacturing division, where he was working on troubleshooting installations and improving generators. He quit Edison Machine works after 6 months since he did not receive a bonus, for redesigning generators and the arc lighting system. Later, he patented an arc lighting system and met investors who helped him, to form the Tesla Electric Light and Manufacturing. However, the company did not do well, and he had to survive merely $2 per day by working in different electric shops.
The Eureka Moment was when in one afternoon when he was walking with a friend in the City Park and reciting poetry, the vision of induction motor, complete, perfect, operable, came into his mind like a flash. He drew with a stick on the sand, the vision he had seen. Tesla with the help of another investor formed Tesla Electric Company, where he developed induction motor running on alternating current. Then, he negotiated a licensing deal with George Westinghouse, A royalty of $2.50 per AC horsepower produced by each motor. Tesla travelled to Paris, to conduct experiments that proved the existence of electromagnetic radiation, including radio waves.
He attempted to develop a wireless lighting system, based on near-field inductive, and capacitive coupling and conducted a series of public demonstrations. Tesla began investigating what he referred to as radiant energy of “invisible” kinds after he had noticed damaged film in his laboratory, later identified as X Rays. Tesla noted the hazards of working with the circuit and X-ray producing devices.
He demonstrated a boat that used radio control. He was also working on the idea that he might be able to conduct electricity by long-distance through the Earth or the atmosphere. He set up an experimental station at high altitude in, Colorado Springs, a large coil operating in the megavolts range, producing artificial lightning. He claimed to have developed his own physical principle, regarding matter and energy. He obtained around 300 patents worldwide for his inventions. We are using most of his inventions, in current age like alternating current, radio waves, wireless charging, mobile phones, remote control and the list goes on. And all this, he did a hundred years back.
