This is much like a Dumbbell, except with multiple columns between the upper and lower decks.


(picture needed)

  • The top platform is a square, for ease of FractalTiling. If we have an edge unit of 10 meters, then we can build squares at 10x10, 20x20, 40x40, etc, and they can all tile together.
  • The columns are spars or open truss (whatever is cheapest) at each corner, platform above, submerged ballast/buoyancy below.
  • It is desirable to have at least 1 spar for protected access to underwater / surface.
  • The columns are set slightly in from the edge of the platform. This allows for LowerAndSneak.

Requirements Analysis

(As compared to a Dumbbell)

  • Safety
    • Should be safer, because multiple columns can support a platform with much less stress on the spars. (Still has shear problems if the whole structure tilts).
    •  ?? Also should be more stable ??
  • Cost - Unknown effect.
  • Pretty - Seems less pretty to me.
  • Modular - Can be locked together / tiled just like a dumbbell, except even more solidly, b/c we are not worried as much about stresses induced by combining platforms, because the multiple column design is solider and "squarer".
  • Cargo - Much easier to hoist things up, because we have wide support for the top platform, don't have to worry about unbalancing things.
  • Scalable - I think it scales fine both up and down.
