@magwas | you might consider the evolutionary approach as a guideline.
This means: the next step of seasteading is the marine engineering of today developing a step further along the evolutionary line
… with a light twist toward longer stay - less ship like - more island like - the basic inspiration is existing yachts, cruiseships, oil rigs, floating wharfs, floating marinas, floating dry docks, afloat ship repair installations, etc…
Floating heavy industrial concrete building method | bubble cluster structure | oil rig base |
Next development step | light floating honeycomb shells | freeforming instead of mass cast | wave impact safe dome clusters | ramform floating marinas | light shell building method |
The designs will be the same designs that are out there, and working well already - they will be scaled up a bit in size - and scaled down a factor 10 in cost per squaremeter real estate.
Short living steel plate construction (designed for short living ships in quick transport ) will be replaced by longer living and more permanent ( 200 years design life) concrete shells (as we see it already in the north sea oil rig developments, wind turbine bases, undersea tunnels, and bridges. ) .
Actually there are people living at sea in this very moment - some of them for months in a row . Some of them in bays (the mayority) some of them in open sea. ( oil rig workers | fishermen | yachties | military personel | Tanka | etc. )
Tanka, Uros, and similar cultures are living in floating cities for at least 1200 years showing that living at sea is not only for the rich.
Venice - “The floating City” has a successfull business model based on oceanic trade and ships for 1500 years.
Floating Marina City - New Venice - light concrete honeycomb shell construction.
If you imagine a seastead as a “self sufficient prepper thing out in the middle of the oceanic nowhere” this should be considered rather an extreme exotic seasteading flavor than the seasteading default. The closest thing to a seastead we see today is probably a marina or an oceanic port - seasteading will be extremly well connected to the oceanic trade superhighways - rather VENICE than PITCAIRN in the general society setup. Nothing is in short supply in a port. Just make sure you are on the sunny side of globalization and oceanic trade.
Seasteading is a “meta idea” it has many development axes. Seasteads will come in many forms and colors run many business models and host many ideas. Like any city a seastead is not about one thing - it is about a living microcosmos of things, designs, businesses, structures, and ideas, living together as a “integrated organism” in close proximity.
What will be done will be decided rather by investors and business owners than by "political steering ".
In a way you can compare it to internet - there where computers and connections between computers long before internet - but at some point it just transcended into something new without anybody inventing it or steering it. Massivication and availabilty added an new dimension to computer connections internet was born. In the same way the floating marinas yachtie communities and port infrastructure of today at some point will transcend to ocean colonization and the building of full sized oceanic cities . Leading to oceanic societies that are different just as city folk and land folk differentiated in medival times.
Technology is ripe to allow settlements almost everywhere - first in the water mantle of the planet the inner space - later in outer space…
Oceanic Business Alliance Work Hypothesis: Reasonable Self sufficiency for a family of 4 can be achieved in an ocean sphere of 12m diameter (incuding surface independent breathing)
Costs: At Oceanic Business Alliance we handle a cost target of USD 80 per real estate square-foot (TSI handles a target of USD 500 per square-foot ) (floorspace).
A real estate square meter is about 10.7 square foot floorspace - what means the volume equivalent of 2.5 cubic meter space at a room height of 2,5m. (light method)
The black blimp shape built in Cartagena (oceanic business alliance) is the space equivalent of a 68 squaremeter apartment (727 square foot) | cost USD 90 K | displacement 200 tons | it creates a comfortable living space bubble that is equally comfortable in the open sea under storm conditions - no other yacht can give that.
The cutting edge of marine concrete shell technology “submarine habitat” | @nautilusmaker
A seastead is an infrastructure development that allows the come together of many ideas vehicles and business forms on the water.
Phase 1 is concluded the point is made - next in the evolutionary line - Revolution in the real estate market - real estate going oceanic.
Context: sustainability of the human project.
Hypothesis : in the next 3 decades all human activity on the planet needs to become “closed loop” by default
light tubular honeycomb shell - construction principle
lens shape | design Matias Volco | @Matias | light honeycomb shell | wave impact resistent | originally drafted for the Marinea project |
A honeycomb shell structure of the kind that is “out there already”… | draw backs - high cost - short lifespan … high turn around business plans only | budget base USD 120 per day per passenger | 15 years lifespan - too short for real estate applications |
