Man who energised and lit the world

It would be utterly ungrateful if we as a citizens of this century do not know  /  remember   Nicola Tesla , an Inventor and a Scientist and a great  Electrical Engineer, of this century who was also a down to earth Humanitarian !. Today we are very much dependent on his major invention Alternating Current (AC) that we use to run everything from  simple household  electrical appliances to mega factories and mills . 

Nikola Tesla (1826 To 1943) was born in Serbia  ,his father Miutin  Tesla was an orthodox priest and mother  Djuka Mandic  was then  an inventor of many house hold appliances. Nikola studied  electrical engineering  and started his career as an electrical engineer with Budapest based telephone company in 1883.From there he got an insight of building  an induction motor  based on the principle of rotating magnetic field ( dynamo principle ) . Then he worked for French company where he designed dynamos and with his own interest he built  a prototype of dynamo  and tested it successfully. But those days  nobody in Europe  got interested in such radical innovations so  he decided to move to America.

In America ,with Charles Batchelor's  ( Thomas Edison's close associate) recommendation letter he joined with Thomas Edison to work with him in his lab. Those days Thomas Edison's company  generated  and distributed DC ( Direct Current ) with huge  and expensive machinery . Though Edison’s  company generated the high voltage  Direct Current based electricity , it was only able to provide power to only few blocks of area and the cost of the DC generation was very  high ( till now it is expensive to have such DC generators) .Tesla worked for few years improving DC motors in  Edison's  lab,  but then due to difference of opinion in the matter of  generation and efficiency of current ( AC v/s DC)  they got separated .

Tesla joined his  hands  with George Westinghouse ( a capitalist) to  start an electrical distribution company which had won a contract to supply electricity against Thomas Edison's Electric company .It was like a war of currents  DC v/s AC and finally AC won for the betterment of world  as it proved to be inexpensive to generate  and can be transmitted to longer distances with less drop in power. Tesla had  a  childhood dream of harnessing Niagara Fall's  power to generate  an electricity so in 1895 he built  first hydroelectric power plant  and   went on to demonstrate that an Alternate Current (AC) can be generated with Hydel power system  inexpensively.

Apart from invention of Polyphase Alternating Current (AC) , Tesla invented  many more useful things to mankind .Following are  few to name.

1. AC induction motor:  Which is the soul of indusrial motors and  all  rotary home appliances .

2. Tesla Coil : Used in most of the communication devices.

3. First Invention of X-Ray ( Same time when Roentegen had invented his x-ray devise): Though Tesla's design was much superior he didn't  take priority on his invention ,instead he congratulated Roentegen for his discovery ! .

4. Invention of Radio waves propagation in 1896  : Much before Marconi  as we know as inventor of present day  Radio.

5. Ground breaking invention to transmit electricity without cables : During this testing Tesla was able to send electrical waves for miles through a special antenna without any wires or cables!.

6. In one of his specialized experiments based on Terrestrial Stationary Waves : He was  even able to transmit electricity through earth  safely  for a distance of about 40 KM  and lit 200 bulbs !

Nikola Tesla was born genius  and  had a nobel vision of distributing electricity for the whole humanity for Free ! . Later in early 1900 he continued  with his brilliant inventions  and was co-funded by three of the famous bankers in America who literally threw away his long time partner George Westinghouse by un-ethical means .Later Tesla parted with these bankers  since they were against the good intention of Tesla to distribute electricity to everyone for a free. In later years he traveled all over the world to educate people in the field of electro magnetism and their pros and cons .

Though Tesla invented many of the electromagnetic devices and systems ,he was aware of the ill-effects of these on living beings .So it is said that during his last years he even invented instruments  and various methods to counter-act the bad effects of   EMF (Electromagnetic Fields) which are low frequency  magnetic and electric  fields  radiating from domestic  AC power line( wires) and appliances  and EMR (Electro Magnetic Radiations)  a high frequency magnetic and electric waves moving through the space generated by Radar, TV towers, Cell/Mobile towers, Microwaves, and high tension power lines.Some companies are still manufacturing these inventions for  EMF/EMR safety invented by Tesla.

A honorary doctorate was awarded to Tesla in 1894 by Columbia and Yale University.  And in 1912 Nobel prize was announced  jointly to Edison and Tesla for their marvels in the field  of physics ,but none of them turned up to receive it  as they don’t wanted to share the prize with each other !.Tesla remained as  bachelor till the end of  his life and dedicated  all his time and efforts  to  most valuable discoveries  ( 111 patents  are in his name) for the betterment of  his fellow mankind.He left this world on 7th January 1943 in Newyork in an car accident ( later it was said that his death was conspired). With great sense of gratitude, please join me in thanking Nicola Tesla for his in-valuable inventions and discoveries for humanity  on most of which currently we are dwelling our lives comfortably !.
