On the opening of the telephone exchange in Budapest, in Hungary, 1881, Tesla became the chief electrician to the company. His first invention was the telephone repeater.
The telephone repeater was his first invention.
The Hydroelectric in Niagara Falls by Tesla, was the first of it's kind. Yes he did.
He worked at Budapest Telephone Exchange where he made his first invention.
He made his first model in 1888 from the ideas he convieced in 1883.
That was the alternate current which put to Edison electric monopoly in the late 1800s.
Tesla had it first. A mysterious fire put that on hold but it was known because he did lectures on the radio. Marconi used 17 patents granted to Tesla to make his radio. Tesla let him go ahead and work his company but the patent was granted to nikola Tesla.
1905
As early as 1892, Nikola Tesla created a basic design for radio. This was before Marconi. As a mystery, his lab caught fire and Marconi was the first to be awarded the patent. Authorities realized that Marconi used Tesla's patent to make his radio and the patent was granted back to Tesla in 1943.
Nikola Tesla
Nikola Tesla is the father of Robotics. Tesla discovered remote control and patented a radio controlled robot-boat in November 8, 1898 (Patent #: 613.809) in 1898.
New York Tesla demonstrated "the transmission of electrical energy without wires" as early as 1891. When Tesla was 41 years old, he filed the first basic radio patent (No. US645576). The year was 1897.
In 1888 Tesla designed the first practical system of generating and transmitting alternating current for electric power. The American rights to this epoch-making invention were bought by the American inventor George Westinghouse, who demonstrated the system for the first time at the World's Columbian Exposition in Chicago. Two years later Tesla's alternating-current motors were installed at the Niagara Falls power project.
