Acionna's Sorrow Ocean Cities Technical Details

- Excerpt from lecture given by Doctor Hilmar Edersson given at 2134 New Sydney Engineering Expo.

Here on Acionna’s Sorrow, we believe that science is a very strong and powerful part of writing good science fiction. Of course, that should be obvious since it is considered science fiction, but sometimes sci-fi writers often forget what science is. In this case, we have opted to stick to hard science while also allowing for some fantastical elements to allow for a story that has fascinating and amazing elements. This way, we keep it entertaining and interesting while also keeping it believable, and that is the purpose of this short series of documents here: To enumerate the technologies and explain them in a way that maintains believability and realism as much as possible.

[/a]; however, that structure was only around three hundred meters across with a sustainable population of only one hundred people. We wanted a structure that was capable of housing thousands of people while remaining ecologically neutral. We wanted the ability to submerge the city as well, though we did not want the city to remain in a fixed location. These were aspects that the Sub-Biosphere could not account for since creating a large multi-kilometer diameter city in the form of a sphere drastically limited its locomotion. The ocean only had an average depth of four kilometers, so this was understandably a problem.

Afterwards, we took a look at Shimizu Corporation’s Green Float. The city was a wonderful and amazing concept, and personally I greatly enjoyed it. I loved the idea of an ecologically-centered city design and I loved the divisions of the city. Once again, though, it proved to be a problem. The city was large, it supported up to one hundred thousand people with absolutely no waste. It was ecologically friendly with a massive amount of biodiversity and carbon negative with self-sufficient power generation. It was even modular, capable of refitting until it grew to the size that it needed. However, it could not submerge. A submersible city was what we wanted and this city did not satisfy that requirement. So, we were at a bit of an impasse. What could we do?

And then epiphany!

Having had experience with writings about space exploration and designing space ships and space stations, we thought about something there. A common shape that people often associated with space flight and science fiction in general was the flying saucer, a disc-like craft whose shape gave it all-round aerodynamic stability and a very strong and stable superstructure on which anything could have been mounted. So, we adopted this design for our cities. Albeit, we made the design extremely large.

Thus we have the agreed-upon design of Acionna’s Sorrow and Poseidon’s Fury: An ellipsoid of massive radii with modules protruding off a massive central piece. We gave this design the ability to submerge with powerful thrusters and ballast tanks that afford three-dimensional movement; we gave it locomotion with the same propulsion systems; and we gave it the ability to be completely self-sustaining via renewable energy, cyclic plant and food production, biodiversity with plants and animals, and also a very efficient waste management system. The connecting bridges to the modules from the central ellipsoidal may have been unrealistically long, but what was good fiction without good exaggeration?

Here is an image to help people visualizing what the shape of each part of the city may be. Just imagine eight of these smaller ones, two kilometers in diameter each, connecting to a massive eight kilometer diameter central hub. Also remember that they extend five hundred meters above and below the x-plane of the city, or above and below sea level if that term helps. Also the hull is significantly more solid than that though there are massive bar windows at certain points as well as numerous viewports. The upper levels, though, were largely hardened glass of a future mix type to facilitate the exposure to sunlight for plant growth. Materials science was not really a strong suit of the original members of the forum, but at least it left room for development and creativity.



Oh, another bit of information to note is that each module was designed to be detachable from the central hub. Each module was also designed to be fully self-sufficient, self-powered, and self-contained. Essentially, one city was a total of nine different cities with one giant one in the center.
