Tesla Greatest Inventions (part II)

Here the rest of the greatest creations of Nikola Tesla

5) Radio

With all due respect to the Italian often credited with inventing radio - Guglielmo Marconi - it was Nikola Tesla who first innovated the concept. Unfortunately, when he was preparing to transmit a signal in 1895, his entire lab went up in flames, and all was lost. But not the idea, of course. Even so, Marconi was soon all the rage for his “invention” that Nikola claimed was done with numerous Tesla patents, but in 1943, Tesla was redeemed when the U.S. Supreme Court upheld his original patent. However, this came shortly after his death. Oh well.
4) Wireless Communications
Ok, maybe Tesla didn’t invent the idea of “free energy,” but he did manage to start building a wireless communication tower known as Wardenclyffe tower thanks to the financial support of J.P. Morgan. By displaying the relationship between a transmitter and receiver station, Tesla paved the way for our world of today, where we browse the World Wide Web and send text messages. In 1893, however, it was just another crazy Tesla idea, but you better believe it was an important one. 
3)  X-Rays
If you’ve ever broken a bone, you’ve hopefully visited a doctor for a complete exam. This kind of experience can be traced back all the way to 1894 when Tesla began studying radiant energy, but the aforementioned 1895 lab fire destroyed all of his experiments. Months later, the German Wilhelm Rontgen “discovered” X-Rays, which led Tesla to build on his theories by incorporating his Tesla coils. And so, radiography was born thanks to the innovations of one Nikola Tesla.
2) Fluorescent Bulbs
The original fluorescent lamp went on the market in the 1930s, but it came after decades of work from a variety of inventors. One of them was Tesla, who introduced his “electrodeless lamp” or induction light at the World Columbian Exposition in Chicago in 1893. This occasion marked a split between Tesla and his former mentor Thomas Edison, who would become known for developing a long-lasting electric light bulb.
1) Alternating Current
It was known as the “War of Currents.” On one side, you have Thomas Edison and General Electric promoting DC (meaning: direct current) electricity, and on the other you have Tesla’s AC (meaning: alternating current) theory backed by Westinghouse. Edison created a culture of fear by showing just how dangerous electricity could be, while Tesla shot it through his entire body. How about that? And it was Tesla's AC motor design that was ultimately adopted in modern times. Tesla invented and innovated many designs over the course of his 86 years, but none more essential than alternating current.
