1. The Tesla Turbine: The Bladeless Engine
What It Is
The Tesla Turbine, invented in 1913, was a bladeless turbine designed to convert energy with unprecedented efficiency. Unlike traditional turbines with blades, the Tesla Turbine relied on smooth, parallel discs and the principle of boundary layer flow to move fluids and generate power. Tesla envisioned it as a low-cost, high-efficiency alternative to the steam engines and combustion turbines of his time.
How It Works
Tesla’s design featured discs placed closely together on a shaft, with minimal spacing to maximize fluid adhesion. When a fluid, such as air, steam, or water, was forced through the turbine, the viscous drag caused the discs to spin, transmitting energy to the central shaft. This process eliminated the need for blades, reducing mechanical friction and wear. Unlike conventional turbines that suffered from energy loss due to turbulent flow, the Tesla Turbine maintained laminar flow, improving efficiency significantly.
In addition, Tesla’s turbine could be operated in reverse, serving as both an engine and a pump. This dual functionality gave it versatile applications, from energy generation to fluid propulsion systems.

How It Worked
The Tesla Coil, a high-frequency transformer, was at the heart of these experiments. By generating massive electrical discharges, Tesla created artificial lightning that could reach incredible lengths and intensities. During his time at his laboratory in Colorado Springs, he produced bolts of artificial lightning over 100 feet long, with thunderous sounds that could be heard miles away.
Tesla theorized that by directing electrical energy into the atmosphere, he could ionize certain layers, creating a chain reaction of energy flows. This process could potentially influence atmospheric conditions, enabling localized weather manipulation. For example, Tesla suggested that artificial lightning could be used to generate controlled rainfall by energizing atmospheric moisture.
Why It Was Forgotten
Tesla’s ideas about weather control were dismissed as fanciful during his time. While his ability to produce artificial lightning was undeniable, the broader implications of weather manipulation were met with skepticism. Critics argued that Tesla lacked the scientific tools to measure and control such large-scale atmospheric effects.
Funding limitations also played a significant role. Tesla’s experiments at Colorado Springs were costly, and without financial backing, he was unable to advance his research further. Additionally, concerns about the potential misuse of weather control technology may have contributed to the abandonment of these ideas.
