Re: [Spaceships] Questions for Open Space
Well, is here anyone to explain Open Space Farms' rules?

My interpretation is that larger open spaces have deeper soil to support larger vegetation. An SM+8 Open Space is 0.05 acres (~200 m^2) and 50 tons, or 250 kg/m^2. Soil is about 1,330 kg/m^3, so that's about 19 cm of soil (7.5 inches). That's enough for grass and flowers, but not for trees. Even most bushes want a meter or more for their roots -- with only 20 cm of soil, you could probably just push them over. As the Open Space gets bigger, its increasing mass/area ratio allows the soil depth to increase to the point where it can support larger vegetation, like bushes and trees, eventually small forests with "bedrock" to shape terrain and hold water features. |

Re: [Spaceships] Questions for Open Space
That’s good, and there’s also some scaling of the support structures and bracing for increasingly large open volumes. Technically that should apply to every system to some extent. It would be annoying to account for, though. But if an average SM+5 system is, say, 5% structure, an SM +15 system might be 15%. I once did the math using frame formulas from Atomic Rockets and tried to adjust performance and capacity but it was really more trouble than it was worth.

But I'm fine with treating the RAW Open Space as a high ceiling luxurious open area, and the Efficient Open Space as densely packed greenhouses and low ceilinged park areas. I've been to people's houses that were like that.

Re: [Spaceships] Questions for Open Space
Yes, what I mean is that there aren’t systems for “structure,” so the spacecraft’s actual frame is presumably divided up and invisibly included in each system. However, bigger ships require a heavier frame to achieve the same acceleration (or land on the same planets, or whatever). That means a larger and larger portion of each system should technically be devoted to structure rather than the system itself, which means capacity and performance of those systems should slowly drop the larger a spacecraft gets.

Re: [Spaceships] Questions for Open Space
A side note on the farming aspect of Open Space. I've seen estimates on how much land it takes to feed a person with modern TL8 tech. The range goes from 2 acres to 0.1 acres, but most seem to be in the range of 1 to 0.25 depending on assumptions about climate and exact set up.
Obviously UltraTech can do far better with gene-engineer super crops. Just for fun, lets assume our ship has TL8 farming and the Efficient Open Space systems. At SM +8 habitats have 6 cabins, designed for up to 12 people. The EOS has 1 area, 0.05 acres. Even at the low end of the spectrum (0.1 acre per person) you need 24 systems of open space to feed everyone. The systems scale at the same rate as each other, so no need to change the ratio for larger ships. Oof. That's a bit more than 1 cargo bay, Captain Janeway. Let's hope TL9+ crops are significantly more productive.

Re: [Spaceships] Questions for Open Space
Below is my Prospector Pioneer Mothership.
(Prospector is name of a state.) Quote:
When I compared SM+8 Open Space and SM+13 Open Space, I realized 1 area of SM+8 Open Space equals 6 cabins as both of these own 1 systems and SM+13 Open Space equals 40 cabins. So I decided my 0.05 acre of Garden (1 Are of Open Space) has 6 floors of indoor gardens. This made my mind peaceful. The remained question is Can people take a rest on the Farm? When people can do, then the use of Garden in my vessel will be vanished. Last edited by Pectus Solentis; 09-24-2020 at 02:57 AM. |
