SciFi Author needs to sanity check for an idea for dynamic support of a structure

+0
−0

Similar to other suggested dynamic structures using kinetic energy to provide structural support, I am considering options for resisting external pressure in a vessel (e.g. a diving bell) by incorporating magnetically supported rotating hoops into the hull. The principle would be similar to an orbital ring but at a much smaller scale, with the force resisting external pressure rather than gravity.

Sketch of rotating mass providing support

I am pondering Options for the circulating mass with angular momentum which will generate the centrifugal pseudo force:

  1. Hoops of copper
  2. Hot Plasma
  3. Cold superfluid
  4. Bose Einstein Condensate.

Question 1: do you see any fundamental - show stopper - reasons this idea could not work (in a Hard SciFi context respecting the laws of physics)?

Question 2: which if any of the materials are suitable? (My preference for narrative reasons would be 4. then 3. then 2.).
