BLOG POST #7

                       They're different inventors, but you can't really say one is greater, because American 

society needs some Edison's and it needs some Tesla's. However, Nikola Tesla symbolizes a 

unifying force and inspiration for all nations in the name of science. He was a true visionary far 

ahead of his colleagues in the field of scientific development. 
                      
                               Nikola Tesla is also known as a great inventor and many people say he was more brilliant than Edison was. In our last post, American inventor Nikola Tesla was born in July of 1856. He came to the United States in 1884. He sold several patent rights his 1891 invention, the "Tesla coil," is still used in radio technology today. Tesla died in New York City on January 7, 1943. Tesla conducted demonstrations of his AC system, which soon became the standard power system of the 20th century, and has remained the worldwide standard ever since. Two years later, in 1895, Tesla designed the first hydroelectric power plant at Niagara Falls, a feat that was highly publicized throughout the world.
                        Also, Tesla pointed out the inefficiency of Edison’s direct current electrical

 powerhouses  that have been build up and down the Atlantic seaboard. Edison’s lamps were weak 

and inefficient  when supplied by direct current. This system had a severe disadvantage in that it 

could not be transported more than two miles due to its inability to step up to high voltage levels 

necessary for long distance transmission. Consequently, a direct current power station was required 

at two mile intervals. Direct current flows continuously in one direction; alternating current changes 

direction 50 or 60 times per second and can be stepped up to vary high voltage levels, minimizing 

power loss across great distances. The future belongs to alternating current which was the defaming 

factor for Edison himself.
