Do speed bubbles manipulate air pressure?

[Sythrin]

The way the border of speedbubbles function, I think is interesting.

Could you stop winds with that and can remain in a storm outside?

Or in space opera age. If a spaceship has breach, could sou stop the air suction with a well placed speed bubble?

An interesting proposal. A cadmium bubble placed around a hull breach in space would slow the rate of flux through the opening certainly. Mathematically, that would be functionally equivalent to a partial balancing of the delta pressure on the two sides of the gap, yes. It's probably important to recall that manipulating time has very peculiar and unintuitive affects on momentum, so anyone inside said bubble could still be harmed by exposure to vacuum.

So something like a charged allomantic granate would be capable?

Yeah, I would expect that mechanized cadmium bubbles could serve as emergency life support deployment systems, but it would only be a bandaid while permanent fixes were prepared and launched if that makes sense. I don't know that they would literally alter air pressure, it would just be functionally like they did.

It seems like this is a somewhat plausible way to stop a ship breach, or at least slow down a rapid decompression. The air still flows through time bubbles, just like bullets it gots deflected because a bubble changes air's momentum. There are WoBs supporting your proposition.

What's it like inside a time bubble on a windy day?

So, I've had to play around a little bit with the air. Air moves in and out, you would still feel it windy, but as I have it you will not feel it from the direction the wind is coming, it will be deflected a little bit. So you might be a little bit in a wind tunnel or something, probably a swirl.

Can you burn cadmium to trap air and move in space like that?

Brandon Sanderson (paraphrased)

That's a plausible extrapolation, but I'll give you a RAFO on that. You're thinking along the right lines.
