Oceanic Concrete Sphere Habitat
January 12, 2014 at 7:50 am #22632
99% of the living space available on the planet is water, so with a population growth of 1 billion per decade, we need to develop ocean colonization to avoid to cut down the last nature reseve on land to make space for megacities.Human settlement of the oceans depends on a affordable squaremeter price for average joe – this means traditional naval technologies and yacht technologies are very much excluded for bringing settlement on the ocean due to their extreme high cost per squaremeter and dependence on strict shipyard maintenance shedules that a floating settlement can not have.Real estate squaremeters floating on the water need to perfom a 200 year service life, and be buildable at building costs compareable to land. Only floating concrete honeycomb and shell structures have this quality.If you think it trough the most economic way to enclose a living space and make it suitable for human habitation is building a sphere.There have been recent studies of the MIT for the ORES wind energy storage sistem that place a 30m concrete sphere in a cost universe that would cook down to a real estate price of USD 2122 per squaremeter.The sistem is planned for 3m thick walls and 400m operation depth. A less extreme sphere with only 1m wall thickness hanging just below the surface would lower this price to about a third of that. This would be already in the range of a normal city apartment.A sphere habitat would not only be the most economic living space feasible for ocean colonization, it would also be a draupner wave impact free seastead, have low anchor and position keeping requirements, so solve all of the problems seastead engineering is struggling with when designing surface floating platforms. . . . Thruster setup on a ocean sphere…The surface part on top of the sphere connecting the submerged sphere with the outside world could have a nice wave impact save shell look like that… In a globalized world the factor of mobility is key and industries are already planning and developing floating fabrication sites for many reasons. Among those are floating breweries developed by the beer multinational Sabmiller, floating LNG terminals, floating harbors, and many more to come.January 12, 2014 at 9:07 am #22633
I think the sphere is a good idea.
There might be some underwater LNP storage ideas too.
It would be good to build one and place it somewhere, under water,
to see the possible use, and the possible future of it.
There is still EEZs (Exclusive Economic Zones) so a country government can
object to placing something like that on the seabed in EEZ. Outside of EEZs there
is still the ISA (International Seabed Authority). The ISA can object.
Enforcing the objection would be a different thing. I would go ahead with the
sphere just to see the objections, and the enforcements of those objections.
The water column is still the ‘High Seas’ = no jurisdiction outside of EEZ, so probably
that is the reason for the floating structures. A sphere can be floating too, just like
the concrete submarine.
Building structures like that on land and launching them to sea might require permission of
the local authorities/governments.
It might be easier to develop a smaller universal building block/unit that can be manufactured
on land and a structure can be assembled in water.
So whatever it is going to be, I am sure there is going to be better and better ideas.
I think, pioneering the process is important.
This thing might be good for me and might be good for others too.January 16, 2014 at 10:25 am #22654

I think this statement is based on false premises. First, there are many predictions about population growth slowing down considerably. Second, there’s no lack of land space, so it’s not a reason to build houses at sea. Third, not 100% available space should be used for living, space must be reserved for resource gathering, and ocean colonization is going in this direction right now. Finally, the point about mobility and modularity is moot, because if people prefer seasteads due to squaremeter price as opposed to liberty price, then they will prefer stationary monolith spheres. Sedentary people won over nomads, after all.
In a globalized world the factor of mobility is key
As I told you in another thread, mobility was always important, globalization simply coincides with mobility renaissance because nomadic lifestyle is often a lifestyle of poor or exploited people and globalization created third world and “always on” working style. For example, it’s frequently not the choice of people to use mobile phones for Internet, it’s because they don’t have desktops and optical fiber access. If you give them choice, they will choose sedentary and authority, that is what has been happening during the last several hundred years. Therefore, politics decides everything, the real key is to create a movement that makes people want liberty, mobility and modularity. It’s wrong to dismiss sedentism and say that mobility is “the key”, it’s only one of the keys. Look at North Korea: not that mobile of a country, yet it builds atomic weapons and launches space satellites under tremendous international pressure.January 17, 2014 at 1:31 am #22662
Ancient Man: Thank you for sharing all that.
ellmer: Lets get going with that concrete sphere.January 17, 2014 at 9:59 am #22667
spark, from what you say above (…build …and see …) i understand that your perception is, that there is any kind of “unclear aspect” in the engineering of floating concrete spheres. The engineering is solved and tested on large scale with projects like Troll A and Rion-Antrion, and 50 other industrial floating concrete structures of similar nature that are out at sea as we speak.
The bridge part built in floating status above has 70m diameter (not only 30m) and is built for 200 year service life – at 70m waterdepth – no maintenance during this service lifespan is possible due to its location.
Ancient, the questions if landspace is scarce, if mobility is key, modern or ancient, should be discussed in separate topics – if you want to open i will answer in detail there…January 17, 2014 at 10:41 am #22668

Well, it’s not me who starts off-topic. You speak about land scarcity and mobility in the opening post. If you think it’s not related to Oceanic Habitat, then why include it in the message?January 18, 2014 at 12:44 am #22675
Where do I pour the concrete?January 18, 2014 at 6:42 am #22676
Spark here is a image that gives the answer.- On a floating building site with a slip form – this is no different as the central core of a highrise building. You have a forming ring that moves along the building …
This is a well established construction technique that you would change somewhat for building a sphere, but basicly very similar.
January 18, 2014 at 12:25 pm #22682
Thank you. It is wonderful. I am just one person. I think it is difficult to move that forming ring by myself.
The question would be; what is the simplest smallest thing I can build alone?
Or with limited amount of people.
Do you build ferrocement boats?January 18, 2014 at 6:24 pm #22688
(… I am just one person…) Spark, you could build something like the exbury egg…
Or a captain nemo boat (space equivalent of a 68 squaremeter apartment see below )…
Have been there, have done that…February 16, 2014 at 9:05 am #22912
Spark – try to tackle the matter along the building of fiber concrete shells. Practical experimentation will lead you down the way…

OK, I will try to build some fiber concrete shells. I need a dinghy.
May be, I’ll try to build one in my garage. How heavy are these shells?
I might need a trailer to transport the dinghy to water. You know, it is
not exactly ocean front property where I live. May be after the big one (earthquake).
How can these fiber concrete shells be extended to make bigger and bigger floating
structures? Would you use scaffolding techniques or something else to expand exsisting
structures? May be concrete cinder blocks?
(I just had to use the word ‘cinder’ to piss katontree off.)
Anyway; I am going to be gone; sailing for the next three days.
I’ll be back.February 17, 2014 at 9:12 am #22921
Sparky making a concrete dinghy, it’s been 15 minutes since i read that, and i am still lmao!February 17, 2014 at 10:16 am #22922
KatOnTri, have you noticed that I do not pay rent for all that space I occupy in your mind.
Go talk to someone who care about you.February 17, 2014 at 10:42 am #22923
Sparky, you aren’t worth me allocating space for. But if i see you on the water, i’ll go the other way. And i already know no one cares about me, that’s no insult. I’d bet that 50% of people who read your posts will believe you should build a boat hull with cinder blocks (as you say), and that’s an instant 50% who i wouldn’t be friends with. A good 50% of the rest wouldn’t be friends with me because i am correct, and they aren’t, and i know it, so good riddance to them as well. I am not building to be away from land because it’s a great place to be, i am building there to be away from you and your friends.
