Tarzan's Journey to the Inner World: The idea of a hollow earth with unique biosphere and archaic state has captivated imagination for long, but using vacuum airships for such a journey faces challenges like continuous supply of lighter-than-air gas and building a light yet strong vessel.
The novel "Tarzan at the Earth's Core" by Edgar Rice Burroughs, published in 1929 and 1930, features Tarzan's journey to the inner world via a vacuum airship. The concept of a hollow earth with a different biosphere and archaic state has been a popular science fiction theme since at least Jules Verne's "Journey to the Center of the Earth" in the 1860s. The idea of a hollow earth has captivated people's imagination for a long time, despite not being scientifically plausible. The novels discuss the challenges of using vacuum airships for such a journey, including the need for a continuous supply of lighter-than-air gas and the difficulty of building a vessel that is both light enough to be lifted by the vacuum and strong enough to withstand atmospheric pressure. The novels also explore the potential use of rare elements or metals to overcome these challenges. Despite the fantastical nature of these stories, they accurately identify some of the limitations of existing lighter-than-air technology.
Vacuum airships fly by displacing atmosphere based on Archimedes Principle: Vacuum airships, using Archimedes Principle, fly by displacing atmosphere with hydrogen, offering potential benefits over traditional air travel despite historical challenges with hydrogen.
Vacuum airships, which fly based on Archimedes Principle and fluid displacement, have been proposed by various science fiction authors as an alternative to traditional airships. Hydrogen, despite its flammability, is an attractive option due to not requiring a vacuum to be carried, as it can be pumped out of the chamber. Vacuum airships have been featured in works by Peter Watts, Iain M. Banks, and Neal Stephenson, among others. Tarzan, a character from Edgar Rice Burroughs' novels, also travels extensively, often encountering large animals. Archimedes Principle, discovered by the ancient Greek inventor and mathematician, states that objects submerged in a fluid are pushed upward by a force equal to the weight of the fluid displaced. This principle explains why boats float by displacing an equal weight of water. Vacuum airships work by displacing the atmosphere, creating lift and allowing the ship to fly. Despite the historical challenges with hydrogen, the potential benefits of vacuum airships make them an intriguing alternative to traditional air travel.
The force of buoyancy comes from gravity: Buoyancy is caused by pressure from fluid displacement due to gravity, allowing less dense objects to float
Buoyancy, the force that makes objects float, originates from gravity. This might seem counterintuitive since buoyancy and gravity seem to be opposing forces. However, when an object is submerged in a fluid, whether it's water or air, gravity pulls the fluid towards the Earth's center, creating pressure. This pressure pushes up on less dense objects, causing them to rise. For instance, a balloon floats because the heavier air around it rushes down to fill the space, and the balloon, being less dense, resists this movement. This principle applies to ships on water and objects in the air, like balloons and dirigibles. By taking up a large space with a lighter-than-air gas or having an empty chamber, these objects can utilize atmospheric buoyancy to float.
The origins of vacuum airships can be traced back to the works of 17th century Italian Jesuit priest Francesco Lana de Terzi: Francesco Lana de Terzi, a 17th century Italian Jesuit priest, was one of the earliest proponents of vacuum airships, inspired by advancements in vacuum pump technology.
The idea of vacuum airships dates back much further than one might expect, with its roots tracing back to the 17th century and the works of Italian Jesuit priest Francesco Lana de Terzi. Lana's groundbreaking book, "Prodromo dell'arte Mestra," discussed the possibility of human flight through mathematical calculations and an understanding of physics. Of particular interest to Lana were recent advancements in vacuum pump technology, which he believed could be used to create lighter-than-air aircraft. The first vacuum pump was invented in 1650 by German scientist Otto von Guericke, and Lana's work influenced subsequent advancements in ballooning and aeronautics.

From Mars trips to metal airships: A history of lighter-than-air travel dreams: From early Mars trip visions to the failed attempts of metal airships, the history of lighter-than-air travel is filled with intriguing ideas and setbacks, keeping the dream of vacuum airships alive.
The concept of vacuum airships, while not a new idea, has a long and intriguing history. As early as the 1700s, people were envisioning trips to Mars using vacuum airships. However, it wasn't until the late 1800s and early 1900s that metal airships, albeit not vacuum ones, were built and tested. Otto von Guericke demonstrated the power of a vacuum by drawing together copper hemispheres that teams of horses couldn't pull apart. Later, in 1897, the first metal airship, the Prussian Airship No. 1, was built, but its rigid construction caused it to crumble. Despite this setback, the idea of a fast, metal airship persisted, and in 1929, the Metal Clad Airship Corporation was formed to build an aluminum-clad helium airship, the ZMC 2, which could reach speeds of 100 kilometers an hour. Although vacuum airships have yet to be realized, thinkers like Lana have proposed designs using vacuum spheres to lift vessels off the ground. Lana's proposal, while whimsical in appearance, was based on the current understanding of physics and addressed potential objections, such as uncontrollability and floating into space. The history of metal airships and the ongoing pursuit of vacuum airships demonstrate the enduring fascination with the possibilities of lighter-than-air travel.
Balancing buoyancy and weight in vacuum airships: Creating a vacuum for buoyancy in airships requires adding significant weight, which may counteract the desired effect. Ethical and military implications of vacuum airships remain uncertain due to feasibility challenges.
Controlling vacuum levels in a sealed chamber can help achieve buoyancy, but creating and containing a strong enough vacuum requires adding significant weight to the chamber, which can counteract the desired buoyancy effect. This balancing act raises questions about whether it's possible to achieve sufficient buoyancy without adding excessive weight or causing the materials to collapse. Additionally, there have been speculations about the potential military applications and ethical implications of vacuum airships, with some believing they could revolutionize warfare or even be opposed by divine intervention. Despite these theories, the feasibility of creating a vacuum airship remained uncertain due to the challenges of containing the vacuum without crushing the containing spheres.
Chicago's Pursuit of Vacuum Airships for High-Speed Transportation: Despite a group's efforts to create vacuum airships for high-speed transportation in Chicago during the late 1800s, scientific criticism and the inability to create a strong and light enough vacuum shell hindered their success.
During the late 1800s in Chicago, a group of individuals, led by a doctor named Debassett, were deeply invested in creating vacuum airships for high-speed transportation of passengers and freight. They even managed to raise funds and turn to Congress for additional support. However, their efforts were met with scientific criticism, particularly from aeronautical authorities Octave Chanute and Albury Francis Zam, who publicly denounced the vacuum principle as a fallacy due to the inability to create a strong and light enough material for a vacuum shell. Despite Debassett's insistence to build one and prove them wrong, the lack of such a material proved to be the Achilles heel of the concept. This pursuit for a vacuum airship went on for about 20 years, and it's interesting to note that there were other Illinois-based inventors also trying to raise funds for airships during the same time period. The dream of air travel was in the air at the Chicago World's Fair, and while vacuum airships didn't come to fruition, it's fascinating to imagine what could have been if they had succeeded.
