Serbian-American physicist Nikola Tesla is known for his work on electricity and energy. In 1893, he patented a steam-powered electric generator or oscillator, which he claimed caused an earthquake in New York City in 1898. The oscillator produced electric currents of a constant period and high frequency, with steady and uniform vibrations. Tesla also believed his invention could be used to cure diseases and have applications in other fields of science and technology.

What You'll Learn
The oscillator was patented in 1893
The electro-mechanical oscillator, also known as "Tesla's Earthquake Machine", was patented by Nikola Tesla in 1893. The device was a steam-powered electric generator that produced electric energy and could be modified to generate mechanical vibrations.
The oscillator consisted of a piston vibrating in a cylinder, which caused an up-and-down motion at high speed, producing electricity. Tesla aimed for superlative steadiness of vibration or frequency, which he successfully achieved. The oscillator was designed to produce electric currents of a perfectly constant period, and these currents were further raised in pressure by "step-up" transformers and condensers.
The machine had a highly regular tunable oscillation, which Tesla used to set the frequency in his high-frequency electrical and wireless transmission experiments. The oscillator was also used in Tesla's experiments with underground prospecting, which he dubbed telegeodynamics. He theorised that by using his machine to send vibrations through rocks underground, he could match the Earth's frequency and cause earthquakes.
In 1898, Tesla caused an earthquake in downtown New York City with a small version of his oscillator. He had been experimenting with vibrations at his laboratory on East Houston Street, and the resulting vibrations were so powerful that they alarmed neighbours and caused the police and ambulance to be called, as well as causing heavy machinery in the building to fly around.
Tesla also believed that his oscillator could be used in medicine to cure diseases such as consumption and cancer, as well as having applications in other fields of science and technology.

It was a steam-powered electric generator
Nikola Tesla's electro-mechanical oscillator was a steam-powered electric generator patented in 1893. The oscillator was a reciprocating electricity generator. Steam was forced into the oscillator and exited through a series of ports, pushing a piston up and down that was attached to an armature, causing it to vibrate at high speed and produce electricity. The upper chamber of the oscillator's casing had to withstand pressures of 400 psi (2.8 MPa) and temperatures exceeding 200 °C.
Some versions of the oscillator used air trapped behind the piston as an "air spring", increasing efficiency. Another variation used electromagnets to control the frequency of the piston's oscillation. Tesla developed many versions of the oscillator and saw it as a potential replacement for inefficient reciprocating steam engines used to turn generators.
At a birthday party in 1935, Tesla claimed that a version of his oscillator caused an earthquake in downtown New York City in 1898, earning it the nickname "Tesla's earthquake machine". He also claimed that the oscillator could destroy the Empire State Building with "five pounds of air pressure" (34 kPa) if attached to a girder.
The oscillator's highly regular tunable oscillation allowed Tesla to set frequencies in his high-frequency electrical and wireless transmission experiments. There were also claims that the oscillator had a physiological effect on people, acting as a laxative.

Tesla claimed it caused an earthquake in New York City
Nikola Tesla patented his electro-mechanical oscillator, a steam-powered electric generator, in 1893. The oscillator works by forcing steam through a series of ports, pushing a piston up and down that was attached to an armature, causing it to vibrate at high speed and produce electricity.
In 1898, Tesla caused an "earthquake" in New York City, which drew police and ambulances to his laboratory. This was the result of a small version of his mechanical oscillator, which he claimed could fit in his overcoat pocket. The oscillator generated a resonance in several buildings, causing extreme vibrations. Tesla said that the machine oscillated at the resonance frequency of his own building and he was forced to shut it down.
At his annual birthday party/press meeting in 1935, the 79-year-old Tesla claimed that his oscillator could destroy the Empire State Building with "five pounds of air pressure" if attached to a girder. He also said that he expected to earn $100 million from the oscillator within two years. The oscillator was explored in 2006 in an episode of the TV show "MythBusters", who found that while the device produced vibrations that could be felt hundreds of feet away, it did not produce an earthquake.

The oscillator was also known as the 'earthquake machine'
Nikola Tesla's oscillator, also known as the "earthquake machine", was a mechanical oscillator that Tesla claimed could produce vibrations that would resonate with the natural frequency of structures. The oscillator was patented in 1893 and later in life, Tesla claimed that one version of the oscillator caused an earthquake in New York City in 1898, specifically in the Manhattan neighborhood of SoHo. This earned the machine its colloquial title of "Tesla's earthquake machine".
The oscillator was a steam-powered electric generator. Steam would be forced into the oscillator and exit through a series of ports, pushing a piston up and down that was attached to an armature, causing it to vibrate at high speed and produce electricity. The upper chamber of the oscillator's casing had to withstand pressures of 400 psi (2.8 MPa) and temperatures exceeding 200 °C.
Some versions of the oscillator used air trapped behind the piston as an "air spring", increasing efficiency. Another variation used electromagnets to control the frequency of the piston's oscillation.
Tesla claimed that the mechanical oscillator could destroy the Empire State Building with "five pounds of air pressure" (34 kPa) if attached to a girder. At a birthday party/press meeting in 1935, Tesla stated that he expected to earn $100 million from the oscillator within two years.
The oscillator was explored in 2006 in an episode of "MythBusters", where a device was constructed that produced vibrations that could be felt hundreds of feet away, but did not cause any earthquake-like shaking.
