Here is an idea I’ve been thinking about for a few weeks: wanted to throw it out here and get some feedback!
For a number of reasons, I like the idea of a spherical housing unit (volume enclosed and structural integrity). Prior to seasteading, I was sold on monolithic domes http://www.monolithic.org/ and a floating sphere seems to be the natural extension of this, offering similar advantages and perhaps being constructed in a similar manner.
That being said, I understand that a sphere is not necessarily ideal for all water conditions (I created another thread to discuss the stability of a simple sphere and don’t need to reproduce that discussion here: it can continue on that thread).
My idea was to have spherical housing units (ideally one per family in a few standard sizes but with customized interiors) which are easily mobile so as to take the greatest advantage of the power of markets and the “exit” option espoused by TSI. This could then be paired with modular add-ons (each tailored to specific conditions) to support the sphere. Below I have rendered a few simple mockups:
Basic sphere ballasted to float at about half submerged.
“Catamaran” like module which provides greater stability in shallow seas and allows for a shallower draft (useful in coastal areas where a 50’ diameter sphere with 25’ draft may bottom out). This would be able to float over the sphere, dock with it, and then empty water from the pontoons and lift the sphere out of the water to a significant extent (perhaps a draft of 10’).
- “Spar” like module which provides greater stability in high seas but requires an even larger draft. This is similar to spar modules but places the bulk of the sphere underwater and minimizes the waterplane area to minimize absorbed wave energy. Similar to the “Catamaran” it would dock with the sphere then take on water ballast to partially submerge.
“City” like module which allows numerous spheres to dock (perhaps in multiple layers with a crane system to lift and place them) and provides infrastructure (transportation and utilities) as well as added stability (given the sheer size of the total structure). I have not attempted to illustrate this and there are endless possibilities for the geomery.
“Boat” module which provides power and allows the spheres to be shuttled anywhere they wish to go. Alternatively, the “Spar” and “Catamaran” modules could include a drive system and also serve this purpose.
“Blimp” module which provides lift (ideally after loosing the bulk of the ballast) and could transport the modules over land and place them on a foundation if they were to temporarily used as a land based dwelling. This one is perhaps far-fetched but it’s always fun to dream!
Let me know your thoughts on this idea!
