Hi friends welcome back to What How Why - Telugu
It's 1891* ( Sorry for the Mistake )
Columbia university
A person came onto the stage
He touched the terminals of a high voltage high frequency transformer
That second
2,50,000 volts has passed through the surface of his body
But still he remained unhurt
Everyone was shocked
The person is none other than Nikola Tesla
Why did he risk?
What did he wanted to convey to the people?
What is the rivalry between Tesla and Edison?
Lets know about all of this in the video
Lets get started
19th century
World is in the important stage of industrial development
But in the nights
Candles and gaslamps were only the saviours
In such times
Famous scientist Thomas alva Edison
In 1879
Developed a practical light bulb that works with electricity
But the invention wasn’t alone enough
For it to work
Every household needed electricity
For this
Power plants and electrical wiring was needed to be done
With the aim of providing electricity all over the world
Edison wasn’t alone
A physics student in Austrian University was working for the same too
He was Nikola Tesla
But both had completely different visions in providing electricity
Edison used Direct Current (DC)
While Tesla used alternate current (AC)
He believed it was more efficient to use
Commen Down Below if you want a video on AC - DC
After Edison has developed the light bulb
Everyone needed electricity to use them
For this
Power plants and Wiring are needed
So, Edison along with other investors started the works
In 1882
They constructed the first power plant in Pearl Street
Similarly they constructed power plants in many other areas
But the major problem is that
Each powerplant used to supply power only in a range of 1 to 2 Km
So more number of power plants were needed to be constructed
But still
Providing electricity to all is a revolutionary idea back then
So many investors invested in Edison’s company to build the powerplants
But for the company not to go into losses
Powerplants were constructed only in highly populated areas
This left villages and remote areas without electricity
Tesla believed that many of such problems can be solved with AC
He also believed that AC is more efficient than DC
So he started working on it
After AC motor was successful
He wanted to explain about it to Edison
But before that, he wanted to show his caliber to Edison
Tesla solved many problems that troubled Edison and his company
As the time ran
Edison company developed very much
It supplied power to many major industries in America
But the DC generators used by Edison company
Were breaking down too often
These problems can be solved by AC
Tesla explained Edison about his model
But by then itself
For construction of power plants for dc systems and
For the development of dynamos
Edison and his investors have put in a lot of money
Now to develop the AC system, a lot more money is required
It might also hinder the growth and business of his company
Edison Realising this,
told Tesla
That the AC is dangerous and cant be controlled
He also has written off the idea telling that there are safety concerns
He also offered 50,000 USD if Tesla fixed the problems in existing DC systems
So Tesla worked hard to resolve all the problems in DC generators
But Edison replied that he only joked
He also did not pay Tesla the money
Tesla resigned from the company as his hardwork isn't being respected
After this
Tesla faced many financial problems
After a small time,
An investor named Westinghouse came to know about Tesla’s AC solution
He liked Tesla’s idea
So he took his patent license and started investing on it
Tesla got right opportunity at the right time
By 1888
Edison company wasn’t able to supply power as per the demand
In the same time
With Westinghouse’s investment
Tesla set up his own lab for research on AC systems
For sending power to long distances and
For large machines to work,
High voltage is needed
But for the facilities in those days
Dealing with such high voltages is very dangerous
So, to deal with high voltages safely
Tesla used transformers
This helped him to control voltages easily
And AC systems were run safely
He proved that AC is more economical than DC and provided better results
So people started supporting him
With this,
Edison company ran into losses
With this,
Edison started spreading that AC is dangerous to use
In addition, to prove his point, Edison has done many worse things
He executed Animals and Prisoners to prove AC was dangerous
Despite of doing all this, Edison achieved nothing
He even received a lot of negativity from the society
As a reply to Edison’s spree
Tesla to prove that AC is safe,
Tesla started performing experiments on himself
In 1893
The Chicago world fair contract was acquired by Tesla’s partner Westinghouse
On May 1st 1893
In a fair attended by lakhs of people\
Tesla's AC generators supplied the power
As a matter of fact
With this itself, Edison lost the war of currents
But still he did not stop using the DC power systems
And after this
One of the World’s largest natural power sources
Niagra falls power generation contract was acquired by Westinghouse’s company
This created a revolution in electrical industry
With this
Tesla – Edison electricity battle came to an end.
But following this
Westinghouse lost legal battles with Edison company
So he went to the edge of bankruptcy
To bring him out of losses
Tesla left his patents license fee also
despite of knowing that he will lose millions
he did it only to because everyone will receive electricity with his AC systems
in 1895
in a fire accident that happened in the lab
Tesla lost all his research equipment that he is using from years
He also fell into financial trouble
Despite having many ideas for innovations
Tesla found no investors
So they remained as ideas
Ideas like global communication network development
Were halted in the middle due to financial problems despite investors like JP Morgan coming forward
Many such ideas were way too ahead of Tesla’s time
So investors also did not support him much
If you want a detailed explanation video about other such brilliant ideas of Tesla
Don’t forget to comment down below
99% of electricity used currently all around world is AC.
In addition
The man who invented induction motor
The man who played a key role in the development of modern science
Tesla died off poverty and health problems in 1943
And that's all for today people
