The 10 Inventions Of Nikola Tesla That Changed The World


Nikola Tesla Inventions

Serbian-American engineer and physicist Nikola Tesla (1856-1943) made dozens of breakthroughs in the production, transmission and application of electric power.


1. Alternating Current

Without question, the most important inventions from Nikola Tesla involve his contributions to alternating current (AC). That today runs in our homes ,industries etc.

2. Tele-automation

In 1898, at the Electrical Exhibition at Madison Square Garden, Tesla showed off an invention he called “teleautomaton“, which was a boat controlled by radio waves

3. The Induction Motor

An induction motor uses alternating current and essentially has two parts – a stator and a rotor. The stator stays stationary (duh) and uses electromagnets to spin the rotor that’s in the middle.

4. The Adams Power Plant Transformer House

The Niagara Falls Commission was looking for a company to build a hydroelectric plant that would harness the mighty power of the falls for years

5. Neon Lamps

While fluorescent and neon lights weren’t discovered by Tesla, he did make many contributions to the advancement of both. What’s interesting is that no one working with cathode rays, which are the electrons observed in vacuum tubes like neon lights, really came up with a practical application for the technology.Tesla saw an opportunity and experimented with running electrical particles through gases, developing four different types of lighting.

6. Radio

The inventor of radio is a point of contention. In 1895, Tesla was getting ready to transmit a radio signal a distance of 50 miles but before he could do that, his lab burned down, delaying the test.

7. Shadowgraphs

There is some evidence that Tesla knew a little bit about X-rays before Röntgen made his research public. Tesla’s own research was stopped when a fire destroyed his lab in 1895, shortly before Röntgen discovered the technology. When Röntgen published his findings, it helped inspire Tesla to create his own X-ray using a vacuum tube, which produced pictures that he called “shadowgraphs.”

8. The Tesla Turbine

n the early 20th century, the world saw the rise of the piston engine in automobiles. In an attempt to compete against the piston engine, Tesla developed his own turbine. It was bladeless and used smooth discs that spun in a chamber, and worked when fuel was combusted before entering the main chamber that contained the discs.

9. The Magnifying Transmitter

Tesla became obsessed with transferring power without wires and thought it was possible to do it at higher altitudes, so after securing funding he set up a lab in Colorado Springs in 1899. There, he built the largest and most powerful Tesla Coil, called the Magnifying Transmitter.

10. The Tesla Coil

  • The Tesla coil was invented in 1891 and uses two coils, a primary and a secondary, with each coil having its own capacitor. A capacitor, like a battery, stores energy. The coils are connected to a spark gap, which is just open air where the spark can generate, and the result is that the Tesla Coil can shoot lightning bolts, send electric currents through the body and create electron winds.
