NIKOLA TESLA INVENTION LISTS

INVENTION LISTS

Tesla discovered, designed and developed ideas for a number of important inventions — most of which were officially patented by other inventors — including dynamos (electrical generators similar to batteries) and the induction motor. 

He was also a pioneer in the discovery of radar technology, X-ray technology, remote control and the rotating magnetic field — the basis of most AC machinery. Tesla is most well-known for his contributions in AC electricity and for the Tesla coil.

AC Electrical System

Tesla designed the alternating-current (AC) electrical system, which would quickly become the preeminent power system of the 20th century and has remained the worldwide standard ever since. In 1887, Tesla found funding for his new Tesla Electric Company, and by the end of the year, he had successfully filed several patents for AC-based inventions.

Tesla's AC system soon caught the attention of American engineer and businessman George Westinghouse, who was seeking a solution to supplying the nation with long-distance power. Convinced that Tesla's inventions would help him achieve this, in 1888 he purchased his patents for $60,000 in cash and stock in the Westinghouse Corporation.

As interest in an AC system grew, Tesla and Westinghouse were put in direct competition with Thomas Edison, who was intent on selling his direct-current (DC) system to the nation. A negative press campaign was soon waged by Edison, in an attempt to undermine interest in AC power. 

Unfortunately for Edison, the Westinghouse Corporation was chosen to supply the lighting at the 1893 World's Columbian Exposition in Chicago, and Tesla conducted demonstrations of his AC system there.

Hydroelectric Power Plant

In 1895, Tesla designed what was among the first AC hydroelectric power plants in the United States, at Niagara Falls. 

The following year, it was used to power the city of Buffalo, New York — a feat that was highly publicized throughout the world and helped further AC electricity’s path to becoming the world’s power system.

In the late 19th century, Tesla patented the Tesla coil, which laid the foundation for wireless technologies and is still used in radio technology today. The heart of an electrical circuit, the Tesla coil is an inductor used in many early radio transmission antennas. 

Tesla coil

The coil works with a capacitor to resonate current and voltage from a power source across the circuit. Tesla himself used his coil to study fluorescence, x-rays, radio, wireless power and electromagnetism in the earth and its atmosphere. 

Free Energy

Having become obsessed with the wireless transmission of energy, around 1900 Tesla set to work on his boldest project yet: to build a global, wireless communication system — to be transmitted through a large electrical tower — for sharing information and providing free energy throughout the world. 

With funding from a group of investors that included financial giant J. P. Morgan, in 1901 Tesla began work on the free energy project in earnest, designing and building a lab with a power plant and a massive transmission tower on a site on Long Island, New York, that became known as Wardenclyffe.

However, doubts arose among his investors about the plausibility of Tesla's system. As his rival, Guglielmo Marconi — with the financial support of Andrew Carnegie and Thomas Edison — continued to make great advances with his own radio technologies, Tesla had no choice but to abandon the project. 

The Wardenclyffe staff was laid off in 1906, and by 1915 the site had fallen into foreclosure. Two years later Tesla declared bankruptcy and the tower was dismantled and sold for scrap to help pay the debts he had accrued.

Death Ray

After suffering a nervous breakdown following the closure of his free energy project, Tesla eventually returned to work, primarily as a consultant. 

But as time went on, his ideas became progressively more outlandish and impractical. He grew increasingly eccentric, devoting much of his time to the care of wild pigeons in the parks of New York City. 

Tesla even drew the attention of the FBI with his talk of building a powerful "death ray," which had received some interest from the Soviet Union during World War II.

Nikola Tesla scientists

Nikola Tesla was a Serbian-American engineer and inventor who is highly regarded in energy history for his development of alternating current (AC) electrical systems. He also made extraordinary contributions in the fields of electromagnetism and wireless radio communications.

ISRO APPLICATION

Earth Observation Applications

Earth Observation Satellites of ISRO has been successfully able to establish many operational applications in the country. Both at Central and State level, there are large number of users who utilise space based inputs for various purposes. Some of the important missions of ISRO, in terms of IRS series of satellites, that has enabled unique applications of space based imaging are, Cartosat-1 & 2, Resourcesat-1 & 2, Oceansat-1 & 2, Risat-1, Megha-Tropiques, SARAL, Scatsat, INSAT series, and host of other satellites. ISRO is in the verge of realising next generation of these satellites, as part of continuity of missions, to ensure that the user community is continuously benefitted from space inputs for sustainable development and good governance.

The hallmark of Indian space programme is the application-oriented focus and the benefits that have accrued to the country through these programmes. The societal services offered by Earth Observation, SATCOM and the recent NavIC constellation of satellites in various areas of national development, including tele-education and telemedicine, are standing examples of applications oriented space programme of India. Remote Sensing applications projects at National, State and Local levels are being carried out through a well-established multi-pronged implementation architecture of National Natural Resources Management System (NNRMS) in the country. The architecture of space programme in India emphasises on the applications, with active participation of user-community from Government, Academia and Industry. During past many years, Indian Remote Sensing Satellite constellation has taken giant strides in ensuring many areas of application, operational. Some of the most prominent ones are Agricultural Crops Inventory, Water Resources Information System, Ground Water Prospects, Forest Working Plans, Biodiversity and Coral Mapping, Potential Fishing Zones, Ocean State Forecasts, Rural Development, Urban Development, Inventory & Monitoring of Glacial Lakes / Water Bodies, Location based Services using NavIC constellation, Disaster Management Support Programme (Cyclone and Floods Mapping & Monitoring, Landslide Mapping & Monitoring, Agricultural Drought, Forest Fire, Earthquakes, Extreme Weather Monitoring and experimental Forecasts and so on).

Geospatial technologies, remote sensing, satellite communication and navigation systems are providing many new ways for effective management of natural resources. This has resulted in enabling variety of data and information products for societal benefits and also helping planners and decision-makers to embark upon unique people-centric services. Web Geoportals and mobile technologies (Bhuvan Geoportal) are the other popular platforms, being used by Governments, to provide information services and solutions at all levels, which are proving to be effective. The Government system has successfully adopted  to use such technologies for the benefit of people at large. ISRO works closely with Central & State Government departments/ ministries, Industry and Academia in ensuring best of solutions for optimal management of Natural Resources, support services for good governance and societal development.
