Tesla invented the first alternating current (AC) motor and developed AC generation and transmission technology.
Because of AC's advantages in long distance high voltage transmission, there were many inventors in the United States and Europe during the late 19th century trying to develop workable AC motors.[3] The first person to conceive of a rotating magnetic field was Walter Baily, who gave a workable demonstration of his battery-operated polyphase motor aided by a commutator on June 28, 1879, to the Physical Society of London.[4] Describing an apparatus nearly identical to Baily’s, French electrical engineer Marcel Deprez published a paper in 1880 that identified the rotating magnetic field principle and that of a two-phase AC system of currents to produce it.[5] Never practically demonstrated, the design was flawed, as one of the two currents was “furnished by the machine itself.”[4] In 1886, English engineer Elihu Thomson built an AC motor by expanding upon the induction-repulsion principle and his wattmeter.[6] In 1887, American inventor Charles Schenk Bradley was the first to patent a two-phase AC power transmission with four wires. "Commutatorless" alternating current induction motors seem to have been independently invented by Galileo Ferraris and Nikola Tesla. Ferraris demonstrated a working model of his single-phase induction motor in 1885, and Tesla built his working two-phase induction motor in 1887 and demonstrated it at the American Institute of Electrical Engineers in 1888[7][8][9] (although Tesla claimed that he conceived the rotating magnetic field in 1882).[10] In 1888, Ferraris published his research to the Royal Academy of Sciences in Turin, where he detailed the foundations of motor operation;[11] Tesla, in the same year, was granted a United States patent for his own motor.[12] Working from Ferraris's experiments, Mikhail Dolivo-Dobrovolsky introduced the first three-phase induction motor in 1890, a much more capable design that became the prototype used in Europe and the U.S.[13][14][15] He also invented the first three-phase generator and transformer and combined them into the first complete AC three-phase system in 1891.[16] The three-phase motor design was also worked on by the Swiss engineer Charles Eugene Lancelot Brown,[13] and other three-phase AC systems were developed by German technician Friedrich August Haselwander and Swedish engineer Jonas Wenström.[17]

Simple resistance you waist alot of the charge.
You mean when passing a current thru a resistor, charge is not conserved?! Those electrons evaporate somewhere?
I can pass electricity through rubber if i have enough voltage but its a waist of energy.
Voltage is NOT energy. Drop of voltage multiplied by current multiplied by time IS energy. Don't you think increasing voltage decrease I2R losses?
In HVDC power lines, do you have an idea of the magitude of Ohmic losses vs Corona loss???
I think you don't know what your talking about! Stop wasting my time.

That was paid from his native country.
What if he accepted that Nobel price? What if he never abandonned his EXTREMELY lucrative patent right to Westinghouse for the sole purpose to avoid Edison win the AC/DC war?
Source? And the New Yorker was still not a 'dump' as claimed.

Never said the New Yorker was a dump!
But you make a point by asking for my src on who paid for the hotel for Tesla!
Which you didn't bother to provide.
Will definitively check if I have kept some writen documents copies!!!
I read your cop out excuse currently. I doubt any evidence will be forthcoming about Jesus Tesla.

Doesn’t say much for your source (that you didn’t link to, btw).
