Solar panels could be used to generate electricity on the asteroids surface, or a nuclear reactor could be used for continuous power generation. Why hasn't the Attorney General investigated Justice Thomas? New external SSD acting up, no eject option. [9][10] Fermilab discovered 17 potential "ambiguous" candidates, of which four were in 2006 called "amusing but still questionable". Process of finding limits for multivariable functions, How to intersect two lines that are not touching. Navigation equipment: Navigation equipment is important for accurately navigating the spacecraft to the asteroid and for guiding the mining and refining operations on the asteroid. Outotecs Kaldo furnace is a rotary furnace used for smelting and refining various metals, including nickel, copper, and zinc. A Dyson swarm is a collection of individual, smaller "harvesters" of some kindthat could be solar panels used extremely close up, for examplethat are loosely circulated. Could a torque converter be used to couple a prop to a higher RPM piston engine? In 2015, astronomer Tabetha Boyajian spotted a mysteriously dim star, its light flickering irregularly in a way that scientists had never observed before. They can accomplish this by using space-based stellar energy harvesting swarms. TLDR 1: All useful energy comes from moving things from a low-entropy to high-entropy state, and doing something useful in the middle. For example, Matrioshka brains have been proposed to extract energy for computation, while Shkadov thrusters would extract energy for propulsion. Estimates suggest that Mercurys crust may contain around 10^20 kilograms of metal, including significant amounts of iron and aluminum. Use MathJax to format equations. KelvinPlanck statement and entropy derivation. However, I can provide a general step-by-step procedure that would be involved in such an endeavor: Again, its important to note that building a Dyson sphere around the entire solar system is purely hypothetical and far beyond our current technological capabilities. We would need significantly more material, potentially from other sources such as mining other planets or moons in the solar system, or developing new methods for obtaining and processing materials. Tungsten Tungsten is a dense and heat-resistant metal that could be used for constructing the supports and wiring of the Dyson spheres energy transmission system.

Webb Space Telescope Image Shows Bright Galactic Collision, 2.29 billion years ago, This Cataclysmic Event Transformed the Makeup of Earths Crust. Hsiao and his collaborators from the Institute of Astronomy in Taiwan, brings us to the very edge of possibility itself. Q: What kind of fuel cells and solar panels would we be able to use? More information: Tiger Yu-Yang Hsiao et al, A Dyson sphere around a black hole, Monthly Notices of the Royal Astronomical Society (2021). "In this paper, we consider and discuss six types of energy sources: the CMB, the Hawking radiation, an accretion disk, Bondi accretion, a corona, and the relativistic jets from two types of black holes: a non-rotating black hole and a rotating black hole," the researchers explain. For a star the size of the sun, with an power output of about 3.8 x $10^{26}$ watts, this would require a DS area of about $$A = \frac{3.8 \times10^{26}}{3.2\times 10^{-6}} = 1.2\times 10^{32} m^2 $$. A black hole will turn anything you throw into it to maximum entropy so it shouldn't be surprising that you can get energy by dropping things in. If you transmit it, relativity makes that complicated; if you store it, you have to lift it out of the black hole's gravity well. Estimates suggest that Ganymedes surface may contain around 5 x 10^18 kilograms of metal. Nickel Nickel is abundant in the metallic cores of the rocky planets and can also be found in asteroids and comets. However, we can use current market prices as a rough estimate. I shall edit my answer accordingly. In fictional accounts, the Dyson-sphere concept is often interpreted as an artificial, hollow sphere of matter around a star. Give me a few examples of mining robots for mining metals on Psyche and their approximate cost. The idea comes from the concept of the Alternative ways to code something like a table within a table? [7], Dyson-style energy collectors around a distant star would absorb and re-radiate energy from the star. Launch vehicle: $500 million to $1 billion, Mining robots: $5 million to $20 million per unit (depending on the type and complexity of the robot), Drilling equipment: $10 million to $50 million per unit (depending on the type and complexity of the drill), Metal refining equipment: $50 million to $100 million per unit (depending on the capacity and efficiency of the equipment), Storage and transportation equipment: $10 million to $20 million per unit (depending on the size and capacity of the equipment), Power generation equipment: $50 million to $100 million per unit (depending on the type and capacity of the equipment), Communication and navigation equipment: $10 million to $50 million per unit (depending on the type and complexity of the equipment), Human support equipment: $50 million to $500 million (depending on the extent and complexity of the equipment). [20], Stellar engines are hypothetical megastructures whose purpose is to extract useful energy from a star, sometimes for specific purposes. Older adults who napped at least once or for more than an hour a day had a40% higher chanceof developing Alzheimers than those who napped less. Since then these giant spheres later sometimes imagined as distributed panels rather than single continuous shells that can be constructed by advanced civilizations to capture their stars energy have become known as Dyson spheres. Nassim Nicholas Taleb, author of Fooled by Randomness and The Black Swan. It uses a bucket-wheel excavation method to excavate regolith and other materials. Design the Dyson sphere to be modular, allowing for individual components to be assembled in space and gradually added to the structure over time. Q: Ok, now lets see a few examples of relevant metal refining equipment and their approximate costs. Can you extract much energy by encapsulating the hole entirely? A: Here are a few examples of storage and transportation equipment that could potentially be used for storing and transporting metals on Psyche, along with their estimated costs: Its worth noting that the cost of storage and transportation equipment for use on Psyche would likely be much higher than the above estimates, as the equipment would need to be specially designed and built to operate in the unique environment of an asteroid. It would produce far more energy than even a normal Dyson Sphere. Only at the event horizon, the coordinate speed of light is zero, and the pencil is supposedly falling 299,792,458 m/s faster than that. This would require specialized storage containers and transportation equipment, such as spacecraft or cargo ships. With tweaks that ensure even greater accuracy, we will soon be using chatGPT and its descendants to design complex technological projects and explore creative ideas. I'd suggest that "minimum" distance depends more upon the technology available to the builders than anything else. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Recheck that answer. TechRadar is part of Future US Inc, an international media group and leading digital publisher. It is believed to contain water, carbon, and other minerals that could be valuable for space exploration and construction. Q: Ok, now lets see a few examples of relevant communication and navigation equipment and their approximate costs. The mission would involve sending a spacecraft to the asteroid to extract the desired metals. The researchers behind the new study suggest that building a Dyson sphere around a black hole would allow an alien civilization to garner energy from six sources: By not only relying on radiation as the main source of energy but a Dyson sphere around a black hole would also collect five times as much energy as one around a star, according to the study. : You cant pull energy out of a black hole, its physically imposible, just like you cant travel in time. Storage and transportation equipment: The refined metal would then need to be stored and transported to a construction site or to Earth. To absorb the accretion disc luminosity, a Dyson ring or a Dyson Swarm could be a Aliens Might Be Using Dyson Spheres to Harvest Energy From Black Holes, Scientists Say, A Dyson Sphere May Bring Humans Back From the Dead. The first modern imagining of such a structure was by Olaf Stapledon in his science fiction novel Star Maker (1937). This would require specialized refining equipment, such as smelters and chemical processing equipment. That'd be a very interesting feature to be included. These days, astronomers talk instead about Dyson Swarms dense arrays of orbiting energy collectors. Protect a planet against a black hole attack. Under the right conditions, the matters self-gravity overwhelms everything else, leading it to collapse into what we call a singularity where all the mass gathers in a single geometric point. Two Missions Will Investigate, Dazzling! In principle, no, you cannot make a Dyson sphere which is indistinguishable from the CMB. The reason is fairly simple. Let's start with a blackbody This difference in speeds is precisely that referred to above by ceiling and floor observers. Since a blackbody radiates uniformly in all directions, the fraction of the energy emitted by any portion of the DS intercepted by the BH will simply be the BH area divided by half the area of DS. Heres how it works. I think Dirk has a valid point, but +1 for rigor and effort and a fun read. The swarm could be made of many individual collectors placed all around the different parts of a black hole in order to best collect from the accretion disk, the corona, and the relativistic jets. Platinum: Platinum is a valuable metal that is highly resistant to corrosion and oxidation, making it useful in a variety of industrial and scientific applications, including the construction of the Dyson spheres electrical components. Number of asteroids required = Mass of Dyson sphere / Mass of average asteroid Number of asteroids required = 5.03 x 10^5 kg / 1.7 x 10^19 kg = 2.96 x 10^-14 asteroids. Additionally, the cost would depend on the specific design and capabilities of the robots required for the mission. Yes, but a sphere surrounding a BH has a central sink at effectively 0 degK. Give me some details on the kind of rocket or launch vehicle that would work. Doing that is really hard work because it isn't gravitationally stable. If space vehicles can accelerate to whatever their maximum velocity is, they will also have the capacity to decelerate too. One example of a PEM fuel cell that could be used for this application is the Ballard FCgen-H2PM fuel cell. That is, if power is radiated uniformly in all directions, the power level produced by any point on the surface at the center will be the same as if the surface point were at the center radiating outwards to the surface. Imagine doing it by mistake first time. In a recent study, scientists analyzed the possibility of an advanced civilization harvesting energy from a black hole. This is actually a rather efficient way of producing energy, since it can turn up to 40% of the rest mass of matter in the disk into radiation, much better than nuclear fission or fusion. Think about the energy required to carry more and more people into space as the world's billionaires venture outside of our planet, plus the energy demands for NASA's own ambitions to install people on the moon. Share Could aliens suck the energy from black holes with Dyson Spheres? Once the equipment arrived at Psyche, it would need to be carefully deployed and assembled on the asteroids surface or in orbit around the asteroid, depending on the specific mining plan. A growing alien civilization may need to develop a way to harvest the energy of their host star. Black Hole 0.185 22900 1240 22 0.09590235397 O-type 2.165 22900 1240 257 Black holes make better engines for Dyson Spheres than stars. "Our results suggest that for a stellar-mass black hole, even at a low Eddington ratio, the accretion disk could provide hundreds of times more luminosity than a main sequence star.". What could be better than a super freaky idea from the edges of astrophysics? Click to load last save.". Therefore, 4 x 10^20 kilograms of material would not be sufficient to construct a Dyson sphere of the size and composition you specified. [21][22], A precursor to the concept of Dyson spheres was featured in the 1937 novel Star Maker by Olaf Stapledon,[1] in which he described "every solar system surrounded by a gauze of light-traps, which focused the escaping solar energy for intelligent use". However, these estimates should be taken with caution as they are based on current material prices and may not accurately reflect the cost of materials in the future, especially if they are required on a massive scale for such a large-scale project. Nickel Nickel is a durable and heat-resistant metal that could be used for constructing parts of the Dyson sphere that will be exposed to high temperatures, such as the inner layers of the sphere. But imagine indeed that you could build the black hole Dyson Sphere. And what Winterberg is saying is that something's got to give, like the wave nature of matter. Q: Give me a list of equipment needed to mine all the metal on Psyche. The form of 'biosphere' which I envisaged con That's not how black holes work, and probably shouldn't work that way in the game. A: Assuming a constant annual GDP growth rate of 2.5%, we can use the formula: where FV is the future value (i.e., $6.117 x 10^33), PV is the present value (i.e., the current world GDP, which is approximately $85 trillion), r is the annual growth rate (i.e., 2.5% expressed as a decimal, or 0.025), and n is the number of years. Q: What if we include Jupiter and Mercury and completely disassemble them? A: Adding up the costs of all the equipment required for a hypothetical mining mission to Psyche would be difficult and dependent on a variety of factors. We Know How Fast Earth Spins Dont We? A Dyson sphere might be, say, the size of Earths orbit around the sun. But constructing a sphere around a star sounds tricky enough civilizations would need materials that would not tear themselves apart or gravitationally attach themselves around any nearby objects. Knock yourself out. If you're a Type II civilization, you'd get far more bang from your investment building a Dyson Sphere around a black hole than a typical main sequence star. Converting all those hard X-rays to some form that's easier to transmit or store. However, here are some very rough estimates based on current average prices: Using these rough estimates, the cost of 1.901 x 10^27 kilograms of material for the Dyson sphere would be approximately: (0.5 x 1.901 x 10^27 x 0.8) + (0.3 x 1.901 x 10^27 x 1.5) + (0.2 x 1.901 x 10^27 x 1) = $6.117 x 10^33. The basic component is like a little brick, and we know how to build bricks to build solar panels and load them into space. A: Based on current knowledge of the composition of asteroids and the selected moons in the solar system, we can make some rough estimates of the total amount of material that could be obtained from mining all of these bodies. Since this is about 400,000 times the radius of the solar system (using the aphelion of Pluto as the marker - forget the Oort cloud for now), this suggests a pretty heroic structure, even by Dyson Sphere standards, and causes one to wonder exactly where the materials will come from. This can be done through remote sensing techniques, such as spectroscopy, which can provide information on the asteroids mineral composition. If a strong enough material is used, an alien civilization could potentially tame a black hole, feeding it matter to produce energy and harness its force. Earth is far from using a Dyson sphere to harvest our sun, Jupiter, or even a black hole. 16 Psyche has an estimated mass of approximately 1.7 x 10^19 kg. [2][3] Variations on the concept include a single circular band in Larry Niven's 1970 novel Ringworld,[3][26][27] a half sphere in the 2012 novel Bowl of Heaven by Gregory Benford and Niven,[2][3] and nested spheresalso known as a Matrioshka brain in Colin Kapp's 1980s Cageworld series and Brian Stableford's 19791990 Asgard trilogy.[1][3]. The estimated cost for a new LM90 is around $500,000. Connect and share knowledge within a single location that is structured and easy to search. Waves break. That problem was what inspired physicists Freeman Dyson to postulate in 1960 that a sufficiently advanced alien race would reach the point where its energy needs exceeded what its planet was capable of supplying. Further out, it will be much simpler and easier, but require more materials. " Additionally, the cost would depend on the specific design and capabilities of the power generation equipment required for the mission. Black Holes store rotational energy that can be harnessed through magnetic reconnection and dropping material in to the ergosphere. This method, they say, is more intensive than previous attempts to study black hole energy-harvesting, which have only explored the accretion disk (the structure of a black hole that you typically picture) or the cosmic microwave background (CMB), the electromagnetic radiation that remains from the earliest stages of the universe. But, the galaxy is an immense place with an estimated 400 billion stars in it. The original site was designed by S. Abbas Raza in 2004 but soon completely redesigned by Mikko Hyppnen and deployed by Henrik Rydberg. The estimated cost for the Hedgehog project is around $5 million. Not so (in any meaningful way) for the energy which is constantly being generated by the civilization which operates the DS. While matter and energy that fall through the event horizon are lost, stuff that stays farther out can still radiate energy and escape. Put someone on the same pedestal as another. Theres also a possibility that a meteor or asteroid could nudge one of the pieces out of place. Tungsten: Tungsten is a very hard and dense metal that could be used in the construction of the Dyson spheres high-temperature components, such as lighting filaments and electrical contacts. If you go through a black hole there should be a yes or no prompt to enter a new star system you keep your upgrades and tech. I hope it is clear that the BH heat sinking has little effect on the energy balance of the DS. However, a Dyson swarm could be built relatively close to the event horizon, albeit at the massive cost of accelerating the individual satellites to near-light-speed to achieve orbit. The secret to this technique is to choose the right placelike the black hole's coronato collect energy. The major sources of each of these metals in the solar system vary depending on the specific metal. Vesta: Vesta is a large asteroid located in the asteroid belt that is thought to contain significant amounts of iron, nickel, and other minerals. The minimum safe distance for components of a dyson swarm will be determined by the maximum safe orbital velocity for the individual units of the swarm. A swarm of orbiting energy conversion satellites whose orbits leave hole in the swarm from time to time for more matter to be fed in is far more practical. We can start with the Dyson Sphere. Additionally, the cost of actually constructing the Dyson sphere would likely be much higher than just the cost of materials, as it would involve a massive engineering and construction effort on an unprecedented scale. While predominantly focused on the radio signals produced by an alien civilization, the problem becomes what happens if an alien civilization is not broadcasting them for reasons of self-preservation (i.e., you can't come and invade what you don't is there). It could be used for the framework and support structure of the Dyson sphere. There may not even be any other civilizations out there, advanced or otherwise. can one turn left and right at a red light with dual lane turns? We've only been able to detect the presence of a few thousand exoplanets around alien stars. Q: Ok, now add up all these costs and give me an approximate number. The SLS will use a combination of liquid hydrogen and liquid oxygen fuel to power its engines, and it will be able to launch both crewed and uncrewed missions. There are quantised zones where orbits are possible or not possible, so dont take other answers at face value if they involve relativistic speeds or distances within a few radii. You would probably have to ground up whole planets just to get the material you need. A: Unfortunately, I cannot provide an accurate cost estimate for such a large amount of material, as the prices of these materials can vary greatly depending on many factors such as supply and demand, location, purity, and form. How much material would I need to build this Dyson sphere? EDIT It's true that this has so far ignored the black hole, and there is a very good reason - a black hole is very small, particularly compared to the DS. Let's say an individual's memories and mind fit into 2.5 terabytes of storage, which is an extremely low estimatethat means there's a server farm somewhere with 20 billion terabytes, which is 20 million petabytes, or about 20 exabytes. If you like what we do, please consider making a donation. Spacesuits: A high-quality spacesuit can cost anywhere from $2 million to $12 million. Here are some estimates: Based on these estimates, its possible that mining all of the asteroids in the solar system, as well as Io, Callisto, Ganymede, Europa, and Mercury, could yield a total of around 4 x 10^20 kilograms of metal, as well as significant amounts of water ice, sulfur, and other volatiles. Would it be possible to have a small black hole dissipate as it 'sinks' into the earth? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Based on the calculations I provided earlier, constructing a Dyson sphere of this size and composition would require approximately 9.1 x 10^25 kilograms of material. It could also be used for mining operations on an asteroid, such as moving and manipulating mining equipment. After all, dont black holes swallow everything that falls into the event horizon, including light? This is related to this question If the sphere surrounded a BH and used it as a heat dump (as well as extracting energy from it by dropping in mass) could its exterior be engineered to match the cosmic background temperature? So really, the considerations are the size of the hole, being able to safely capture and distribute the power output, dealing with gravitational extremes, etc. However, there are some existing mining robots that could potentially be adapted for use on Psyche. In addition, Io is thought to have significant deposits of iron, nickel, and other metals, although the exact amounts are uncertain. To learn more, see our tips on writing great answers. If we were to completely disassemble Jupiter and Mercury and use all of their material for the Dyson sphere, it would provide an additional 1.901 x 10^27 kilograms of material, which would be more than enough to construct the Dyson sphere. The estimated cost for a new InLine Leach Reactor ranges from $500,000 to $1.5 million, depending on the size and configuration. Robotics and automation equipment: Robotics and automation equipment can also be used for communication and navigation purposes, such as controlling mining and refining equipment remotely. Can a rotating object accelerate by changing shape? The wavelengths of such re-radiated energy may be atypical for the star's spectral type, due to the presence of heavy elements not naturally ocurring within the star. Their goal is to explore the power needs of a civilization making the jump from a type 2 to a type 3 civilization, which could be Earth in as little as 1,000 years, according to their scientific napkin math. What Lies Beneath the Ice of Jupiter's Moons? Iron (used instead of crude steel): $0.20 per kilogram. Per the Stefan-Boltzmann Law, emitted power P is related to temperature T by $$P = \sigma T^4$$ where the Stefan-Boltzmann constant is $$\sigma = 5.6710^{8} W m^{2} K^{4}$$ Learn more about Stack Overflow the company, and our products. The estimated cost for a new Transloader ranges from $200,000 to $500,000, depending on the size and configuration. After a while there'll not be any matter to fall into it, unless you are providing it. The SLS is currently in development and is scheduled to make its first launch in the coming years. Sandviks DE880 is a core drilling rig used for mineral exploration and geotechnical investigation. Indeed, the paper, by T.Y. But is it at all feasible to use a black hole as you'd harness the energy of the sun or another star? Excuse me but isn't a Dyson swam supposed to collect light? Assemble the raw materials into larger components of the Dyson sphere, such as individual panels or segments. This obviously involves some pretty extreme astronomical engineering. The form of 'biosphere' which I envisaged consists of a loose collection or swarm of objects traveling on independent orbits around the star". Electrons etc cannot maintain their identity. Identify asteroids: The first step in asteroid mining is to identify suitable asteroids. Here are some of the major sources for the metals mentioned in my previous answer: These sources are not exhaustive and there may be other sources for these metals that are not listed here. It would be tricky to insulate against that. You probably think of a Dyson sphere as a structure that captures the sun's energy, but what would happen if you built one around a black hole instead?
