10 Inventions That Make Nikola Tesla One of the Greatest Scientists of All Time.
Nikola Tesla, who is well-known one of the greatest scientists of all the times, has gifted many discoveries to the world in every possible way in terms of electricity, light, radio, transmitter and even x-rays. He has made more than 700 inventions and had over 100 patents throughout his lifetime.Despite all his 700 inventions, Tesla was not wealthy. He worked in his room for many years, at the Hotel New Yorker, where he took his last breath.
Take a quick look at some of this greatest inventions:
- Alternating Current
Alternating current actually wasn’t invested by Tesla. However, he gave an outstanding contribution in making its usage simple shall always make it one of his greatest inventions. Tesla, who worked for Edison at that time pointed out the flaws and inefficiency of Edison’s direct current electrical powerhouses.
DC current flows continuously in a direction, whereas alternating current be stepped up to very high voltage levels as it changes its direction 50-60 times per second, thus minimizing power loss across great distances. Though having much bitterness between Edison and Tesla about the AC vs DC war, ultimately, Nikola Tesla developed polyphaser alternating current system of generators, motors and transformers and held 40 basic U.S. Patents on the system. This was bought by George Westinghouse, which marked the nationwide and thereafter, worldwide usage of electricity.
- The Tesla Turbine
In early 20th century, which was primarily the era of piston engine in automobiles, Tesla invented his very own engine in turbine style, which was blade less and used made use of smooth discs that spun in a chamber. The fuel efficiency of his engine was 60% which was proved to be a great achievement in those times as the current fuel efficiency level that we still are in is just 42%.
- The Tesla Coil
The Tesla Coil is another form of his greatest inventions. It is a high-frequency air-core transformer which takes the output from a 120vAC to several kilovolt transformer & driver circuit and steps it up to an extremely high voltage (above 1,000,000 volts) and are discharged in the form of electrical arcs. Tesla coils create extremely powerful electrical fields, which define their uniqueness.
4. Radio and Remote Control
Tesla patented a radio controlled robot-boat which was used for controlling different radio waves in the Electrical Exhibition in 1898. Tesla’s robot-boat was constructed with an antenna, transmitted the radio waves which were again received by coheres.
This transmitted the radio waves into mechanical movements of the propellers on the boat. Thus, the boat directions could be manually operated.
Tesla built the largest and the most powerful Tesla Coil, which was called The Magnifying Transmitter. It had three coils and was 52 feet in diameter. What made it the biggest lightning at that time was the fact that it generated electricity of the order of millions of volts and shot lightning bolts (approximately 130 feet long).
- Neon Lamp
Tesla created the first neon signs at the World’s Fair by taking glass tubes and bending them into famous scientists’ names, in effect creating the first neon signs. Also, he converted black light into visible light by using a phosphorescent substance which was originally created by him himself.
- Shadow graph
Tesla obtained images of a human body which he called shadow graph. Also, Tesla experimented them with reflected x-rays and described features of transmitted and reflected rays.
Besides, explaining changes in x-ray characteristics as being caused by variations in x-ray tubes and electrical generators, Tesla also realized the biological hazards of working with unipolar x-ray tubes.
- Adams Power Plant Transformer House
Nikola Tesla and George Westinghouse built the first hydro-electric power plant in Niagara Falls in 1895, thereby ensuring the beginning of electrification of the world.
- Induction Motor
Nikola Tesla invented the induction motor with rotating magnetic field that made unit drives for machines feasible. What’s more is that he also made AC power transmission an economic necessity.
Despite being a genius, Tesla was not wealthy, even some of his inventions never got recognized. But he will always be remembered for his great inventions.
