Just had an idea about seasteads:
Would it be possible to adjust the floats to let a "basement", having the shape of a half sphere or bowl, made of transparent material, sink a few yards into the ocean?
So that the "ground level" of the living compartment is about at sea level, and you could watch what happens below in a 360° view from the "basement"...
One key to the spar design is that the less surface area at the surface the better. This is where the waves are crashing against your seastead. Ideally they would meet a thin pole, 1mm thick holding your house above it.
As it is, that would not support any structure so we have opted for a steel tube 1.6m wide. We could make it smaller but we want it to be easy for people to walk down a spiral staircase into the spar so they can reach the underwater room with views like this:
Yeah, like this, but all around sea view (if possible).
I was thinking of a floating pole, just anchored with a steel rope, maybe retractable, to keep the low end of the pole more steady. Still some things to think of, like movement compensation and tilting, because auf waves, tide, winds and so on. Physics...
The spiral staircase looks great! I can imagine hanging out there for a while on a daily basis
