So the reason balloons work is that the internal gasses can exert pressure while being of a lower density.

If we can develop a 5SB that isn't locked to a particular reference frame, then it would be easy to build a floating thingamabob.

The 5SB invulnerability would let a light shell hold its shape enough to deal with the lack of internal pressure. Allowing us to build floaty things.
 
I would absolutely come work at that startup, since all the people from the thread that I've met in meatspace have been super cool (thanks for hanging out this morning, @Radvic!), but I don't know what we would actually get up to. Too many diverse interests.

Banking, probably? Step one of IRL uplift is "become really super duper rich so you can fund projects that might stop humanity from killing itself".

What he said. The biggest advantages with using sealcraft is that the shell is much less important in terms of rigidity, as it can just be supported by the barrier structure. The thing that it's needed for is supported any load that's attached. Also, if we can figure out how to vary the amount of air the implosion seal stores, we can vary the buoyancy of the craft, and attain specific altitudes.

We don't even need to do that if we're willing to deal with shitty suspension. Pop vacuum seals to increase lift (in discrete increments) and use a valve to let in air to decrease lift.

The ride would be annoyingly jerky as you increase lift, but that's good enough for government work.
 
I don't think that a valve is the way to go. It introduces a weak point in an otherwise perfectly sealed (heh) structure. Why not use something like another modified storage seal? One that only takes in a certain amount of air, and can be released over a period of time. Then you can have a bunch of them, and have the base state be on the ground. Then, each seal activated will increase altitude by (x) meters, descending achieved by releasing the stored air.

I'm wondering how this can be controlled. Can seals be activated through wires, ones that lead to a central cockpit?

Literally just making it easier to build and research.

Also if the seals break, and that doesn't kill everyone on its own, the valve makes the entire thing somewhat more survivable.

I'm a bit confused by the valve. If the seals break, won't we be descending already, in which case the valve won't help? Also, how would the valve interact with the barriers?

What do you mean by making it easier to build and research?

Not if it's refusing to release the stored air. There are many ways in which it could fail.

It's a simple research project if we don't add slow release to the list of requirements.

We can abandon vessel and henge into blankets.

Well, sure, obviously we'd WANT better methods down but that would be a good stopgap. The sooner we get aerial mobility, the safer we'll be.

e: Aaaaand on that note I just had the glorious mental image of Akane combining Heaven and Youth Technique with Skywalker seals to develop a Pingpong style of taijutsu to use in collaboration with Kei.

Ok, I see why a valve would be useful for that, but it still begs the question of how it would interact with the barrier. Would the barrier cut an object in the way, form around it, or not form at all?
The slow release isn't really necessary, just a thought for having slower transitions in case something goes wrong. Obviously we wouldn't immediately change altitude right away in either case, anyway. But the storage seals are already multiuse seals, and the macerator seal basically has a slow release. It would just be a question of how to have it only intake air, like an implosion seal. There's going to be seal research with either one, as the implosion seal needs to not release the air.

Now I'm thinking about emergency procedures and parachutes/lifeboats

Why bother with valves when we have storage scrolls? We can gather up enough heavy objects (like bags of sand) and seal them away when we want to go up and then release them when we want to go down. By having multiple ballast seals we can control our rates of ascension and descent easily.
 
Sounds like we're all on the same page re: zeppelin engineering, more or less. Nice!

Can seals be activated through wires, ones that lead to a central cockpit?
Hey there, Shneddly! Welcome(?) to the quest!

The closest we have right now is Kagome's chakra-tripwire thing, the lesser Barrier Formation Method. People have been excited about Jiraiya potentially giving us a technique for activating seals at a distance, but we'll have to wait and see.

I mean, parachutes seem like a straightforward invention IC if we're already thinking of blanket-henge-ing to slow our falls, and they're a) more optimizable and b) escort-mission-friendly!

Actually,
The sooner we get aerial mobility, the safer we'll be.
we could totally think up hang gliders too, and figuring out frame + wing materials for those would be a good first step to zeppelin-hood.

Also, as with everything else involving propulsion, slightly-modified storage seals could make these pretty amazing.
 
I just remembered we were supposed to be planning/voting. I'm not sure if I'll be able to tomorrow evening/Wednesday morning, so I'll put a tentative vote in now.

Barrier the balloon, then screw the valve into the hole.

True. But our early tests will be fine without it.

But the storage seals are already multiuse seals, and the macerator seal basically has a slow release.

Nope, there's no slow release on a macerator. It grinds stuff up, but releases it in a single burst.

There's going to be seal research with either one, as the implosion seal needs to not release the air.

Not really. The implosion seal stores a bunch of air, air rushing in to fill that gap destroys the seal, and the destroyed seal releases the air it had stored.

If the implosion seal is triggered in an airtight container, the air in the container will be stored, but since there's no inrush (the container is holding the outside air back) the seal won't be destroyed and its contents won't be released.
