The Ambitious Plan to Harness Energy from Mercury and Beyond
Written on
Chapter 1: Understanding Dyson Structures
The notion of a Dyson sphere is truly captivating. It represents a colossal structure that encircles a star, designed to capture its complete energy output. Such an energy-absorbing shell could supply vast amounts of power to an advanced civilization. Named after astrophysicist Freeman Dyson, this concept arose from the idea that future civilizations would require energy far beyond what their planets could generate. To sustain and expand their infrastructures, they would need to extract energy from new sources. This visionary concept has appeared frequently in science fiction narratives over the years. However, Freeman Dyson himself expressed regret about the association of the idea with his name—primarily because it is largely unattainable.
The sun, which is the nearest star to Earth, boasts a diameter 109 times greater than our planet and has a mass 300,000 times that of Earth. Constructing a shell around such a massive body would demand astronomical quantities of resources, time, energy, and financial investment. The materials required would exceed what is available in our solar system, presenting the first significant challenge. Furthermore, no known material could withstand the immense stresses involved, making the structure inherently unstable and prone to collision with the star due to cosmic debris.
Another critical factor is gravity. If Earth were positioned outside the sphere, the sun's gravitational pull would be insufficient to maintain our orbit. Conversely, if Earth were located within the sphere, the gravitational force would be excessive, drawing us closer to the sun.
To illustrate the scale of this undertaking, it is estimated that merely the framework for the sphere would necessitate approximately 1.7 x 10²? cubic meters of material, equivalent to the resources of two dozen planets. Following that, one would still need to ensure that life on Earth could persist without sunlight, gravity, and the two dozen planets that would have been consumed.
So, is the Dyson sphere concept entirely fantastical? Not quite. There exists a potential solution through a simple alteration in design.
Section 1.1: Rethinking Energy Collection
Instead of a solid Dyson sphere, envision creating rings or panels orbiting the star. This alternative resolves the challenges previously mentioned. Arrays of collection panels would maintain stable orbits and be propelled by solar radiation pressure. Each panel would need to be one kilometer or smaller in diameter and as thin as tinfoil, directing sunlight into compact solar power plants that could harness the energy effectively.
Using this innovative approach, we could access roughly one trillion times more energy than currently available. The implications of such an energy surplus are a topic for further exploration.

Section 1.2: The Reality of Constructing a Dyson Swarm
Though the notion seems ambitious, it's feasible to commence building these collection panels and eventually establish a Dyson swarm in the foreseeable future. However, this monumental project would demand an extensive array of resources. To fully capture the sun's energy, we would need to consume Mercury, Venus, Mars, various asteroids, and even some moons in the outer solar system. Mercury would be our initial target due to its iron-rich core, constituting about 40% of its mass. The oxygen present in its crust would provide essential materials for creating hematite—a highly reflective material used for mirrors for millennia. Additionally, Mercury's low gravity would facilitate the launch of these materials into space.
The initial construction phase would be slow, as our limited energy supply and a scarcity of autonomous factories would mean that the first collector might take around ten years to complete. However, the construction process could accelerate significantly thereafter, thanks to self-replicating machines and enhanced energy supplies from the newly added panels. In approximately 70 years, we could see a considerable start on the Dyson swarm, although Mercury would likely be reduced to mere dust in the cosmos. Alongside this loss, we would also need to devise ways to coordinate the panels to prevent collisions.
Chapter 2: The Pursuit of Interstellar Energy
Astroengineering is a field dedicated to tackling such complex questions and envisioning construction in space. Experts take concepts like the Dyson swarm seriously, and real companies are already gearing up for asteroid mining, with government support boosting investments. In 2021, the market for space mining was estimated to exceed $11 billion. Advanced 3D printers are being developed to fabricate astronomical mirrors, addressing the challenges of traditional manufacturing.
Moreover, a partial Dyson swarm could be established to utilize the additional energy source for more efficient and sustainable energy acquisition methods. After all, a Dyson swarm would only provide power for the duration of a star's lifespan.

Theoretically, only 0.7% of the rest mass of hydrogen fuel consumed at the sun's core is transformed into energy. To achieve maximum efficiency, alternative energy collection methods may be considered. For instance, energy could potentially be harvested from black holes through Hawking radiation or by capturing heat produced by incoming matter.
Curiously, there are even speculations regarding the discovery of a Dyson sphere orbiting star KIC 8462852 in 2015. Observations from the Kepler telescopes revealed unusual fluctuations in the star's brightness. Typically, even a massive planet like Jupiter would only dim a distant star's light by 1%. However, light dimming as high as 20% was noted, leading scientists to rule out dust clouds, collisions, and star spots as possible causes. The most plausible explanation points to comets entering the star's system, though even that would be an extraordinary coincidence.
Ultimately, this may be the reality that more advanced civilizations have faced: the necessity of making sacrifices to progress. To elevate ourselves from a primitive state to one capable of interstellar exploration and dominance, we may first have to consume our own planetary companions.
