🌀🌬️ Flow Dividers for Artificial Gravity in Air
Kardashev range: 0.73–1.7
A rotating habitat inside a larger atmosphere normally loses obscene amounts of energy to windage. This idea is about splitting and staging the flow so breathable air can coexist with rotation without the whole concept turning into a giant brake pad.
Notes
The core question is whether velocity-partitioning structures can create stepped transitions between rotational regimes, reducing shear enough to make very large inhabited volumes practical.
