How Does the Helical Engine Work?

The concept of a helical engine has been a topic of discussion and debate for years. Proposed by Dr. David Lewis in 1996, the helical engine is a theoretical engine design that claims to be more efficient than traditional engines. Despite its speculative nature, it has piqued the interest of many scientists and engineers. In this article, we’ll explore the basic principles of the helical engine and how it works.

What is a Helical Engine?

The helical engine is a proposed engine design that uses a helix-shaped tube to create motion. This tube is designed to rotate on its own axis and move forward at the same time. According to the theory, the helix-shaped tube would compress and expand, creating motion that would turn the engine’s crankshaft. The idea behind the helical engine is that it would be more efficient than traditional engines, which use pistons to create motion.

How Does a Helical Engine Work?

The helical engine is a hypothetical propulsion system that has been proposed as an alternative to traditional rocket engines. Unlike a conventional rocket, which relies on the reaction mass principle to generate thrust, the helical engine makes use of the properties of spacetime itself to generate propulsion. While the idea of using the properties of spacetime to create propulsion may seem like science fiction, the concept is rooted in established physics.

At the heart of the helical engine is a long cylinder with helical-shaped channels cut into its interior walls. These channels are arranged in a specific pattern and are filled with a fluid that can be made to flow through them.

The fluid is heated at one end of the cylinder and cooled at the other, creating a temperature difference that generates a pressure difference within the channels. This pressure difference causes the fluid to flow through the channels, and as it does, the cylinder experiences a force in the opposite direction. This force, in turn, generates thrust that can be used to propel a spacecraft.

While the concept of the helical engine is still largely theoretical, researchers have been exploring its potential as a way to travel vast distances in space. One of the most promising applications of the helical engine is in interstellar travel, where it could be used to propel spacecraft at high speeds without requiring large amounts of fuel. If the concept of the helical engine can be realized, it has the potential to revolutionize the way we explore the universe.

Advantages of a Helical Engine

Advantages of a helical engine include:

  1. Increased efficiency: The helical engine is designed to use less fuel than traditional engines, making it more fuel-efficient. It uses a continuous flow of fuel and air, allowing for greater combustion efficiency and lower fuel consumption.
  2. Reduced emissions: Due to its increased efficiency, the helical engine produces fewer harmful emissions, making it more environmentally friendly. It produces less carbon monoxide, nitrogen oxide, and other pollutants, reducing the environmental impact of transportation.
  3. Increased power: The helical engine has the potential to generate more power than traditional engines of the same size. This is due to the engine’s unique design, which allows for greater energy transfer and more efficient combustion.
  4. Smaller size: The helical engine’s unique design allows it to be more compact than traditional engines. This can lead to reduced weight and improved space utilization, making it ideal for a variety of applications.
  5. Reduced maintenance: The helical engine’s design is simpler than traditional engines, meaning it has fewer moving parts and requires less maintenance. This can lead to reduced maintenance costs and increased reliability.

In summary, the helical engine has the potential to be a game-changer in the transportation industry, offering improved efficiency, reduced emissions, increased power, and reduced maintenance.


The helical engine is a fascinating concept that has the potential to revolutionize the way we think about engines. While the idea is still in the theoretical phase, it has captured the imagination of many scientists and engineers. It remains to be seen whether or not the helical engine will ever become a reality, but it is clear that it has the potential to change the way we power our vehicles and machines.
