5 inventions of Nikola Tesla that are still used today

Nikola Tesla was one of the inventors, great and innovative thinkers, as well as the most prolific electrical and mechanical engineer at the end of the 19th century. Nikola Tesla who was born on July 10, 1856 in Smiljan, Croatia, filed 278 patents and several have been recognized. He is best known for his contributions to the design of modern alternating current (AC) power supply systems. His inventions of alternating current (AC), induction motors and polyphase AC patents helped him and his company earn a lot of money and popularity. One of his best inventions was the wireless-controlled boat which was first shown in an exhibition. During 1893 he suggested that there was the possibility of wireless communication with the help of his device. Here are 5 Tesla inventions that are still in use today, summarized from the Historyhit and Steamdaily pages. 


1. Hydroelectric Power

One of the most impressive products of Tesla’s partnership with George Westinghouse is the Adams Power Station, the world’s first hydroelectric power station. This innovative power plant embodies a long-held hope that the awesome power of Niagara Falls, one of North America’s most spectacular natural wonders, can be harnessed. This project is the indirect result of a competition, organized by the International Niagara Falls Commission, to find a plan that will do just that. The competition attracted participants from all over the world, including proposals for transmitting DC electricity backed by Edison.

But the chairman of the Commission, Lord Kelvin, was impressed enough by the display of Westinghouse Electric’s AC at the 1893 Chicago World’s Fair that he asked Westinghouse and Tesla to develop an AC transmission solution. The project proved challenging and expensive, but despite growing skepticism among investors, Tesla never doubted that it would eventually prove to be a success. Finally, on November 16, 1896, the station was activated and electricity generated by the revolutionary Adams Power Generation Transformer House began to flow into Buffalo, New York. Shortly thereafter, ten more generators were built and the energy from those plants was used to power New York City. 

2. The shadowgraph

Tesla’s research, which is perhaps less well known due to the fire that destroyed his New York laboratory in 1895, is related to the advent of X-ray technology. German scientist Wilhelm Conrad Röntgen is better known for developing the first X-rays on November 8 of the same year, a groundbreaking achievement that won him the inaugural Nobel Prize in 1901. Inspired by Röntgen’s X-rays, Tesla renewed his interest and developed the Shadowgraph using a vacuum tube. His drawing of a shoe with a foot in it, produced in 1896, is considered America’s first X-ray.


3. Radio

Currently the radio is one of the important devices needed when traveling when boredom hit. The creator behind this incredible thing is none other than Nikola Tesla who did a huge amount of research and experimentation on radio waves. Tesla filed his patent in 1897 which was granted to him in 1900. However, Guglielmo Marconi had a similar idea, and applied for his patent but was rejected because it is almost the same as Tesla’s. Marconi took many ideas from Tesla and started his own company. Soon he was able to send a signal that impressed the patent office, thus changing the decision and granting Marconi the patent. Tesla did not have much money to struggle to copy his ideas which eventually led Marconi to become the inventor of radio. As early as 1895 Tesla was ready to send radio signals for 50 miles, from his labs at 33 and 35 South Fifth Avenue in Manhattan, to West Point, New York. However, disaster struck before the groundbreaking test could be completed: a building fire destroyed Tesla’s lab. A year later, Marconi issued his first wireless telegram patent in England.

4. Neon

Lights Neon lights are another example of the technology that Tesla developed, not invented. Tesla had several Geißler tubes and observed that they flashed successively as he adjusted the frequency of the coils. This chance discovery was a dramatic realization of his interest in wireless energy. In 1893, Tesla displayed a selection of discharge lamps that lit without being powered by electrodes or wires at the Chicago World’s Fair. Indeed Georges Claude of France displayed a pair of 38-foot-long neon tubes at the Paris Motor Show in 1910. But it was something akin to the fluorescent lamps that had been developed decades earlier in the mid-19th century by Heinrich Geißler, the German physicist.


5. Induction Motors

Like many of Tesla’s innovations, the award for the invention of the induction motor is a contest for many parties. In this respect, Tesla outperformed the Italian inventor Galileo Ferraris, who developed the same technology at approximately the same time. Although Ferraris presented his concept of a motor that uses electromagnetic induction to rotate its rotor first, Tesla filed for the patent first. Using electromagnets to rotate, Tesla’s induction motors currently power everyday household items such as vacuum cleaners, hair dryers, and power tools.
