Future-oriented inventions, ahead of Nikola Tesla's time

Nikola Tesla (July 10, 1856 - January 7, 1943) was a genius inventor. He invented hundreds of world-changing devices and processes during his lifetime.

The Tesla coil is one of Nikola Tesla's most famous inventions. This invention was the basis for much of his later work.

Essentially, a Tesla coil is a resonant transformer that produces alternating current of extremely high frequency and voltage. This coil consists of two coils that reflect energy back and forth.

Tesla used coils to conduct experiments on electric lighting, electrotherapy, and wireless power transmission.

Magnifying transmitter

The magnifying transmitter generates power wirelessly by harnessing the power of a Tesla coil.

Tesla discovered that when he connected a metal wire to a magnifying generator, he could power his entire laboratory.

Tesla performed an experiment, resulting in the transmitter being able to illuminate a light bulb 1 km away.

Radio controlled boat

Nikola Tesla debuted his radio-controlled boat at an exhibition in Madison Square Garden in 1898. At that time, many people couldn't even understand what they were seeing.

Because Tesla's idea was so unbelievable, he was initially denied a patent.

Tesla said that his technology was the foundation for the birth of robotics, helping to liberate human labor.

Induction motor

The induction motor or asynchronous motor, running on alternating current, was developed by Tesla in 1887 and patented in May 1888.

It uses multiphase electricity, creating a magnetic field to rotate motors, improving energy production efficiency and proving that long-distance power distribution is feasible.

Today, many devices such as vacuum cleaners, dryers and power tools. still use this type of motor.

Hydroelectric

Nikola Tesla was the one who created the generator for the world's first hydroelectric plant at the Niagara Falls system in the US in 1895. 9 of the 12 patents used to build the plant belonged to Tesla.

Neon light

The invention of the neon light is credited to Georges Claude in 1910. But in fact, Tesla tested something exactly like that in 1893. Before that, Tesla realized that it was possible to wirelessly power A glass tube (Geissler tube) containing an argon-like gas with electrodes on each side tested with Tesla coils.

Radio broadcasting

Guglielmo Marconi (pictured), who is credited with inventing the radio telegraph. However, this invention uses Nikola Tesla's technology, so he was rejected many times by the US Patent Office.

Tesla realized that the Tesla coil could transmit messages but his laboratory unfortunately burned down when he was about to test it in 1895.

On December 12, 1901, Marconi successfully transmitted a radio signal across the Atlantic Ocean. Later, he was granted a patent.

Tesla Turbine

In 1913, Tesla invented his own turbine inspired by the piston engine. Tesla's turbines used discs, which were more fuel efficient than turbines at the time that used blades.

Tesla believes it can be used in "power plants of the future" to generate geothermal energy.

Alternating current

Alternating current (AC) is one of Nikola Tesla's oldest and most famous inventions. This form of electrical energy is still used to power homes and businesses.

X-ray photo

On November 8, 1895, X-rays were invented by Wilhelm Röntgen. But back in 1894, Nikola Tesla also experimented with something like an X-ray machine. Tesla is said to have taken the first X-ray photograph in America when he tried to photograph his friend Mark Twain but only captured the metal screws of the camera lens.

Death ray

The death ray emitter that could destroy enemy aircraft from the sky was an invention that Nikola Tesla never actually built.

The transmitter includes a device to create an electromagnetic beam in the air, a high-power generator, an energy amplifier and a device to create a strong electric pulse. According to Tesla, this technology creates a super weapon that can destroy 10,000 aircraft and a million infantrymen from hundreds of kilometers away.

His goal is to turn this super weapon into each country's "defense wall" to preserve peace. However, at that time, the US government believed that this was an unproven idea and lacked practicality, so Tesla did not sponsor this project.
