He experimented with electrical machines that could operate autonomously, though many remained unbuilt. His vision included not just mechanized tasks but also integrating intelligent control mechanisms.
Interesting fact: As mentioned, the boat could be steered by remote control using radio waves, but since the concept of radio waves was not well understood at the time, the audience couldn’t believe what they were seeing. Some people accused Tesla of trickery, thinking that there was a small monkey or even a trained mouse hidden inside the boat, secretly steering it.
3. Earthquake Machine
Nikola Tesla’s earthquake machine, formally known as the mechanical oscillator, aimed to generate powerful vibrations.
Tesla demonstrated that vibrational energy could resonate with structures, potentially causing significant effects, including destruction.
Mechanical Oscillator
The mechanical oscillator was designed to produce specific mechanical vibrations. Tesla created a small device that could be tuned to different frequencies.
When set at the right frequency, the oscillator generated vibrations strong enough to potentially shake buildings and objects nearby.
Tesla tested this device in various settings. One of his notable demonstrations occurred in his New York City laboratory, where it allegedly caused nearby structures to tremble.
Observers noted the machine’s ability to amplify vibrations given the right conditions. Tesla believed a larger version could harness energy to affect the Earth itself.

5. Dynamic Theory of Gravity
Nikola Tesla’s Dynamic Theory of Gravity proposed a radical approach to understanding gravitational forces.
He believed that gravity results from the energy transfer among celestial bodies and their interaction with the surrounding ether.
Energy Transfer
Tesla theorized that gravity is not a force in the traditional sense but a product of energy transfer. According to his concept, mass interacts with surrounding energy fields, causing bodies to attract or repel.
This energy transfer is akin to oscillations in a medium, affecting the motion of objects in space.
He suggested that the ether, an invisible medium, plays a critical role in this process. Masses emit energy, which interacts with this ether, altering gravitational effects.
This perspective challenges Newtonian gravity, presenting it as a complex interplay of energy rather than a simple force.
Proposed Experiments
To validate his theory, Tesla envisioned several experimental setups. One proposal involved utilizing electromagnetic fields to observe changes in gravitational behavior. He believed that manipulating energy fields could simulate variations in mass.
Another idea included testing gravity’s effects on different materials subjected to varying energy states.
By observing discrepancies in gravitational attraction, Tesla aimed to provide empirical evidence supporting his dynamic hypothesis. Such experiments could reveal insights into how energy influences the gravitational interactions between objects.
