Dyson Sphere

Dyson Sphere

Refer to this page http://forum.trek-rpg.net/showthread...rn-of-the-Jedi

In thinking about how to generate a sphere and was looking at a picture of the Death Star and remembered a version I had made up where I generated only a section of the Death Star and then connected them together, this didn’t work well and I decided to generate a single segment of the sphere and then work out what was needed knowing it would work better than the Death Star a mostly solid sphere. I generated the segment as a single plate. The population is the total that is possible. I figure that most of the advanced race would have underground quarters leaving the surface for agriculture and natural landscaping.

This is one segment of 6,539,423,077 total sphere segments and equals 193,069,926,905,559 SU’s of total sphere. This can also be used to generate the ring version pictured three to nine segments wide with 15,000,000 to 450,000,000 (SU’s 442,860,005,559 to 13,285,800,005,559) segments making the ring. Using this you can make it as wide as wanted within reason.

Some of the parts are only in certain segments such as transporters, sensors systems, tractor beams, auxiliary spacecraft systems and Exterior space doors can be found in certain places around the sphere or ring with the notes for how many. The notes are for notes below are for a sphere and should be cut down by a third for a ring version dropping the tractor beams and Exterior Space Doors.

The exterior resistance is so high to withstand the exterior damage of materials crashing into the surface and the rest is just because I could. I wanted a surface that withstand a starship ramming into the surface with no damage to the surface but the higher resistance is for a combined attack of a starships focusing on breaching the hull.

Game notes: No starship can travel warp speed anywhere within one AU of the Sphere as it is radiating a warp dampening field well into subspace. This does not affect the ships traveling at full impulse speeds. This reduces the ability for a ship to use the warp engines to cause damage by ramming a starship into the surface of the sphere.

I admire you dedication to Space Dock mate, and this is one of the most interesting write up's I have seen.

I understand the premise of the Dyson sphere (as in capturing the entire solar output of host star) but I would have added some reserve/emergency power generation (the Solanae Dyson Sphere used Omega particles to generate power, though that sphere was mobile and transwarp capable).

I would also add massive holographic sails so that the interior surface receives a day/night cycle (fauna and flora as well as agriculture works a lot better with a day/night cycle)

Outer hull, I would make it neutronium and effectively impervious to damage (and put the resistance at say 10,000 at least), there are enough SU's to justify it and it seems more in line with the build.

I would eliminated the emergency transporters (25000km's isn't going to get you very far inside a 1Au structure anyway), and instead add a site-to-site transporter system.

Quarters, why not just have expanded and/or just Luxury? Star ships have to worry about space, space stations/terrestrial facilities aren't so constrained and citizens would want the higher standard of living?

I would add some sort of weapons array (maybe orbital weapons platforms inside the sphere) and some exterior arrays.(self defense easily justify's this) One defensive system, if you weren't interested in adding overt weapons arrays, would be a energy dampening field (a 5AU field would basically make the sphere easily defensible)

http://en.memory-alpha.org/wiki/Duonetic_field

I will say a Dyson sphere makes for a great back drop for an adventure and there is at least one story (Star Trek on-line) I know of one concerning such an episode (the Solanae Dyson Sphere)

http://sto.gamepedia.com/Solanae_Dyson_Sphere

I was not aware that the Dyson Spheres were that large; it can be easily modified using the same segment with refiguring the surface size and then breaking down the surface by dividing it by 900 square meters that is the number of the segments. I tried to keep close to the Sphere that was seen in TNG. I was under the thought that the materials of the solar system is encompassing the materials of the system to create the sphere’s exterior.

This version is close to http://www.coldnorth.com/owen/game/s...lic/sphere.htm version.

Neutronium if you refer to the TOS Spacedock you will notice that the resistance is something like only 250 making it kind of flimsy. I had the hull resistance up to 20,000 but I wanted to have a little difficulty to blast a hole through the surface to the interior if it came to it.

I left a lot of it well unfinished for the users to modify for their own use as they are exploring the interior. Any structures inside the sphere are a part of the SU’s that are unused. I can see there be a starship manufacturing facility on the interior surface for ships up to the size of the Andromeda.

As for transporters I like transporters and the emergency transporters are to beam them from the local danger to somewhere safe inside of the sphere. The transporter is a useful tool to move a person or cargo from one place to another without any lag time. If Amazon had that kind of speed.

The Sphere is weaponless as it is from a time in when there was no need and if needed and wanted they can be added, an energy based weapon and missile system if needed. I think that what defenses are they work well.

all good points mate, I was only throwing ideas out.

Standard radius for the typical Dyson sphere is 1 AU, the same distance of Earth orbit. I could see an argument of making them as large as the Goldielocks zone is on any particular star (in my scenario Khan Ascendant the Sol Dyson sphere is 2 AU and encompasses all the inner rocky planets out past Mars). I would say most sphere's would not have planets orbiting internally, but I can't think of any reasons why not? (if any one could throw up reasons why not, please post. If a race has the technology to build a sphere they would most certainly be able to control the orbits of a planet)

http://en.memory-alpha.wikia.com/wiki/Dyson_sphere

As far as the neutronium the episode Relics the shell of the Dyson sphere was described as "carbon-neutronium alloy and was impervious to phaser fire."
http://en.memory-alpha.wikia.com/wiki/Neutronium
Materials are of coarse, sourced from the solar system that is host to the Sphere but that being said other materials could be used. (bought in)

http://forum.trek-rpg.net/showthread...notanium-Armor
when you wrote it up in Space dock it had a resistance of 4000 and cost 160su

Your points about transporters is completely correct , maybe add a site-to-site system as well as all the others?

I didn't think about a Space Dock/construction facility (or three), there would be such facilities included.

Please don't take my suggestions as criticisms mate, I was just trying to add to the project.

I like the impute. You are not being to critical as I am far more critical of my own work. I left much of the sphere undone to allow the adding what ever someone wants to add. Personally I was just fooling around with this in some free time over a warm stretch of weather here. I like the idea of a Dyson Sphere but would not like to live there as I would miss seeing the stars at night.

Weapon emplacements would be needless if there is higher resistance. As for carbon-neutronium alloy I don't remember hearing that in the episode but I haven't watched that episode in a long time.

Oh, another reason for not living there all the ambient heat and radiation generated by the sun goes where? I think it would be hot like an oven or cooking like a microwave. that is why there is shields on the inside as well.

I would like to see any addition to the segment I have above here adding in something making it individual segment.

apparently this is of major concern, heat build up and heat management, from what I have read on the subject would be one of the factors that makes a real Dyson sphere non viable. That is why most postulate a swarm or ring to be the preferred model. (point 13 in the article)

http://www.aleph.se/Nada/dysonFAQ.html

*coughs, gestures back to the post where he postulated the Relic sphere as a swarm of overlapping plates*

Although this is Star Trek, so that heat energy might be converted into something else and stored or even shunted into subspace.

TTK makes a good point, the heat would definitely be stored/converted or shunted. I would also add that "using the radiant energy of a star (the Dyson sphere's purpose) would conceivably include the heat generated by the star.

Visually the Relic's Dyson sphere did look like a "shell" version rather then the swarm version (to me it looked like a solid shell that encompasses the entire star), but that doesn't mean it wasn't like you say TTK.

all this talk of Dyson sphere's certainly has sparked my interest in rereading all of the info I have on the subject, and I have to say while I really like the idea of a traditional Dyson sphere though for practicality the Ringworld version would be the best option, and honestly approximately 3 million Earths is enough space to build a civilization...LoL. I will probably have to track down the book Ringworld and read it.

https://en.wikipedia.org/wiki/Ringworld

Well, the Ringworld version includes being able to actually *walk* on it, due to the centrifugal forces of it's orbit, without Trek supertech—for there to be things on the inside of the "Relics" sphere the inside would need an artificial gravity field.

One of my (unused) notions for Trek-appropriate megastructures would be a 'ringworld' made up of pods like the alien starship from "Beyond the Farthest Star," where the flex and bend of the network would avoid the problems of a rigid ring while providing a structure to traverse.

torsion points, with built in flex joints would have to be incorporated into any large construction (similar to large bridge construction or other such constructions today). Though I would think structural integrity fields would also play a big part in keeping the entire structure in one piece.

If I were to oversee the construction of such a structure (Ringworld) I would still incorporate an artificial gravity field despite the centripetal force generated gravity, redundancy is your friend and alleviates a lot of problems.

How are the spheres being lit like that?

The bottom image looks like a relatively small ball of polished granite with a smaller ball inside, off centre. It definitely does not look like any of the popular depictions of a Dyson Sphere.

The Sphere in Relics was not a swarn of overlapping plates - it was a solid shell over a kilometre thick with a habitable inner surface.

The heat inside the sphere wouldn't be a problem, since the original concept was to harvest all the energy of a star, and heat is just energy.

The closest thing to a statement on the cross-section of the sphere from the script I could find is this:

WORF
No, sir. The exterior shell is
composed of carbon-neutronium.
Our weapons would be ineffective.



Which actually makes it sounds like, yes, there is a differentiation of material throughout the sphere.

I'm judging from the visual appearance when the Enterprise went through the portal. It seemed that the thickness was several times the length on the Enterprise-D's 642m. This thickness would be needed for such things as a soil base and terrain variations, including the seas seen in the Sphere, as well as artificial gravity generators, et cetera Remember, inside a sphere, all true gravity would cancel out, putting the space inside the structure in zero-gee. Also, neutronium would in physics theory need a gravity field to keep it from coming apart. A skin of a few klicks thick would, of course, be a mere gossamer=thin wall on this scale. I did some postulating for my Relics campaign: http://www.coldnorth.com/owen/game/s...lic/sphere.htm

I think the portal isn't necessarily a good determinator of the internal structure for the same reason you can't check out a house's insulation and wall framing walking through the front door.

I'm not necessarily sold on the idea of the spaces between the plates being 'empty'—I mean, this planet is a bunch of solidish plates floating on liquids, so I think that might be a good basis for the internal structure of the Sphere. That also gives you a vast network of 'oceans' made of whatever weird meta-water they produce with harvesting all that energy.

There's also the question of whether the mountains and lakes we see on the inside were actually the intended geography of the interior, or whether it's been around long enough—and abandoned long enough—for those mountains and oceans to be the result of the equivalent of natural geological forces. Or if, say, something impacts on the interior shell of the sphere, can you have million-mile-wide tsunamis? What if the gravity fails in particular sections, and you can literally walk from vacuum to atmosphere to vacuum? Hell, if you have the command codes for the gravity system, you could wipe out whole civilisations at the push of a button.

they did seem to take some liberties with the bottom pic, but most likely to show the detail.

from the episode Relics

What liberties do you mean?

the external lighting that would not be present unless there was another star in the solar system (I was referring to the bottom pic in post #13).

it's funny Dyson originally calculated that a shell only 3m thick would need all the matter in the solar system to be used in construction.

here are few more pics

Yeah, well, this is Star Trek - never confuse it with hard SF. Dyson's original concept was the swarm type, and was not a habitat, but merely energy collectors. All the shell-type spheres are later, derivative concepts. In your latest post, the first image is not a true Ringworld - note the obviously artificial and relatively small small light source in the centre. It's probably only a planet-sized construct.

yeah I was wondering why the "star" in that ringworld version looked strange, you are probably correct. Though even building a planet sized construction would be a massive undertaking.
