Well ideally we'd have dry docks where we would build the initial portions of our base. The first portions of our base would be built like actual barge ships, four or five of them as the foundations of the village where we would lift it up from. We could also have an actual boat where we would have business conducted on the surface. Most boats would be large enough for our village to grow from during the set up phase. And living on the water gives us fish as a primary food source.
I find myself confused. Are you suggesting sailing several ships out into the ocean permanently to serve as an outpost of the village, or are you thinking we'd lift up the boats?
We don't need a flying village, we just need a Helicarrier. Mostly because a flying village needs some kind of food supply. Unless we can find air whales, or plant affinity people for ninja hydroponics.
In addition to
@Traiden's suggestion to fish the ocean under us extensively, I had a thought about this: what if we can get pangolins to bring food with them through the summon realm? Could we contract with a farmer to supply our hidden village?
(
@Dictator4Hire Apologies for being rather contrary here - I think we may be starting from very different understandings of the situation)
Orbit also has the advantage of not requiring constant upkeep to maintain its general position
Orbit actually does require upkeep, at least occasionally (see
Orbital decay - Wikipedia, the free encyclopedia). That upkeep is mathematically intensive, though probably less resource intensive than the cloud city plan.
If we get high enough to necessitate environmental suits to wander outside of the complex and we are using the same propulsion systems as something capable of LEO or GEO, why not just go to space instead?
Why would we go that high, though? Baseline humans have no problems a couple kilometers above sea level, but that's still far enough that no technique I'm aware of can get to us.
Space has asteroids we could mine with MEW and has orbital velocities to use for doomsday weapons.
Space rocks are few and far between unless we decide to launch probes out to the asteroid belt, and that's assuming our background knowledge about space actually applies to MfD. A
Thor shot station is tempting, but again requires math we may just not be able to do, on top of any problems with supplying it.
Furthermore, no ninjas that we know of have a spaceflight technique, but I'm sure there are plenty of ways for them to jump extremely high if not fly or glide long distances.
What ninjas do we know that can jump 2km straight up?? Flight I will grant you, but they still have to know we're there.
Unless the state of math is higher than we anticipated, they also won't be able to hit a target in LEO easily, if at all.
Unfortunately this also applies to us in figuring out how to target kinetic bombardment ordinance, how to dock with our station, how to get back to the ground safely, and how to do orbital maintenance. Unless you're proposing something like "[]Research Keiko: Multivariable Calculus"?
LEO also means that we could launch almost anywhere on the planet and with minimal fuss return to our station. A stationary platform floating in the sky would require longer travel times to get to.
If I have learned anything from Kerbal Space Program, it's that orbiting and docking cannot in any sense be described by the phrase 'minimal fuss'

What leads you to think it'll take longer to get to a stationary platform?
I'm not saying a cloud city is a bad idea, in fact I'm ecstatic people are putting so much thought into it, I just don't see how it's better than an orbital station for a long term construction project. If we need practice with inventions, we could simply make zeppelins which would have the added benefit of being immediately useful for crossing borders effortlessly for trade or simply improved mobility.
I actually agree, depending on what you mean by 'long term'. Hidden Heavens is something we could potentially accomplish on the timescale of a couple months if left to our own devices, but if we can solve the mathematical and logistical challenges I would prefer to be even farther away from the people trying to kill us all.
Re: zeppelins, I don't know if it's worth it to invest in more of the party learning EM (make a seal for it instead maybe?), and that method of travel might be kinda conspicuous for our stealthy merchant empire...
Cloaking seals are a must to hide a sky base if we don't want people getting suspicious because of unusual clouds showing up. Two methods I can think of are making a seal that can apply henge to objects and making twin wall seals that take incoming light and project it from their partner. The henge seal has the downside of being static, so it would be noticeable against a changing background, but it would also protect the henged object from weak wear and tear. If the twin wall seal can project the light of the opposite wall from the same side that it's absorbing light, then we would also be camouflaged from above. Also, based on the diagram of the pieces that the structure would be built with I'm not sure if they already meet this criteria, but a design where there are always two 5BSed objects holding each other up for redundancy would be safer. Like the higher platform cradling the lower platform such that if the BS ran out on the lower one, it would still be held up, and the lower one would obviously hold up the higher one if it happened the other way around.
A henge seal for protecting objects from wear seems to have less utility in the case of a platform that's being made indestructible by 5SB, but actually sounds like a brilliant application generally. We should brainstorm what we could do with it besides just disguising things. You mention timelocking Nobby's barrels below, which is a cool concept.
@OliWhail, maybe we can save on platforms if we base the overlapping edges on
borromean rings. It would require making the the edges out one whole piece of rock and then carving away, with the downside that we won't be able to disassemble them. Currently, we're looking at a ratio of 0.8333... seals per meter of hidden village. If we save on the 3 red xs it comes out to 0.555... seals per meter. Assuming 5 minutes per seal and Kagome and Hazou working in tandem, it would take ~208 minutes of seal making per 100 m^2 the current way or ~137 minutes if borromean rings are a workable solution. Both times are very workable.
Hmmm. I think we need 2 things for them to be workable: the pattern needs to expand cleanly to arbitrary numbers of rings, and we need to work out where we would stick the central seal.
Edit: Ideas on alternate materials: we could use rope instead of nets, fabric, wood or some other substance lighter than granite, wax, glass, ice, sponge, packed mud, bone, paper, or soap.
Edit the second: If we paint or cover a net or some other object in glue, does that count as one object for the purposes of 5BS?
[/QUOTE]
I picked stone as a limiting case and because MEW might let us produce the pieces easily. We would need really large trees for wood, industrial production for wax and glass, etc... Hazou almost always has access to stone.
Painting over a net, though! That's absolutely fucking brilliant. I clearly gave up on that idea too early
Sky-Platform Idea:
We could make a geodesic sphere (
Geodesic dome - Wikipedia, the free encyclopedia) with ridges on the insides of the triangles to give space to insert triangular panes, and latches to hold those panes in place once inserted.
We inscribe the locking seal on the sphere itself, then inscribe the anchor seals on triangular panes and insert them into their slots and set the latches.
Then we activate the seals and everything gets locked in place.
Mmmmm I am wondering about how to design the sphere itself to be low enough volume that the seal will take hold, and low enough mass that we can lift it? Also, where to put 4 anchor seals in a 3-way symmetrical structure?
