A duct whose wall is the same surface that shakes the flow and extracts from it.
A duct is a tunnel that guides a fluid, such as air or water. In a normal duct the wall only guides. The energy leaves with the fluid.
This project designs a duct where the wall does two jobs at once. It shapes the flow into drafts and eddies, and it takes energy out of the flow it shaped.

- PROJECT.md: the device idea, the central conflict in the design, candidate mechanisms, and the prototype ladder.
This project came out of thermal-capture, a research direction on turning heat from the atmosphere into electricity. The full question record is held there.
Project definition only. No device has been built. No performance figure is claimed.
