    please keep the forums on topic – this is in the interest of all participants…let’s talk about Oceanic Concrete Sphere Habitats here: http://concretesubmarine.activeboard.com/t46713498/submerged-living-space-bubble-concept-basics/

    I went to the store a few days ago to buy fiber cement. They had decided to not sell it any more. I can’t keep fighting to have things my way, so i give up and will make my personal little floating castle of 100% steel. The steel is actually lighter, slightly cheaper, and i can disassemble it for transport to the water. Sure cement might last forever, but if i must put steel reenforcing in 1″/2.5cm cement, it’s not going to last much longer than if i used steel and no cement. And i do not need to wait up a week or three for it to set to strength. And the cement would never have the tensile strength of steel, an issue i was having problems with.


    Kat, keep an eye on the required maintenance shedule, and build the structure to enable bottom sandblasting and repainting on a regular base. Steel has advantages and disadvantages like any material you use. As long as your personal castle fits into a drydock and can be taken out of the water once a year your personal version of seasteading can well be built on a steel hull. The forming of round shapes (especially Sphere Habitats) is a bit tricky in steel plating…

    I’m going to keep an eye on Ocean, see how his cement barge things for the houseboat work. Nothing says i cannot experiment with cement after i am floating around. :-)
    I have cold bent 1/2 inch plate, and made a 4ft diameter, 10ft long, cylinder of 1/4 plate steel, and made the ribs for it:
    4ft dia pontoon
    And the bows of the little pontoons i made look truely awesome to me, seeing as how i made them of steel, all cold-formed (but the arc welding was hot, of course)
    bow steel pontoon boat
    I designed, cut, welded, painted the 16ft pontoon boat, and the tilt-bed trailer for it. And i designed and built the overhead bridge crane that moves it all around. And the building it sits in.


    We are certainly off topic on the Oceanic concretes sphere habitat thread, but do i see 12mm marine steel plating in these pictures ?!! this is a thickness considered normal for the shell of 250m merchant ship of several thousands of tons of displacement – looks like “seriously overbuilt” for a floatie like that…

    Yes, you see it correctly in the top picture, the bottom picture is ~.040/1mm (no one believed i could stick weld such thin steel, but there’s tricks). The 1mm steel is pretty sturdy in the curves, you see the hammer laying there, i used to knock the bow into precise position on the pontoon before welding. I showed the pics because you said “The forming of round shapes (especially Sphere Habitats) is a bit tricky in steel plating”, but i can do it. So i figure if Ocean can stucco a wooden barge to protect it, i can make a nice looking steel floating whatever, and do the same. Honestly, i know i will not live forever, and my steel boat will not float forever, the cure will be to make my own “incubator for research” on the water, so i can make a semi-submergeable floating concrete drydock. Such a drydock would be very useful in making and launching new seasteads out where there is no interference. There have been successful concrete floating drydocks made.


    I don’t have the shadow of a doubth that if you can form that bow in steel plating, you also can form a sphere. Looks like you are very crafty in steel – so using that for your “personal castle on the water” makes a LOT of sense to me.


    oceanic concrete sphere tension anchor . oceanic concrete sphere growth
    To envision the oceanic concrete sphere habitat two fotos: A tendon anchor, and barnacle growth on a habitat that has been several months in the ocean. No chance for “paint protection” only concrete can stand that.
    The reasons why oceanic business is the next big thing to come:
    Oceanic concrete shell and honeycomb building.

    Fine, Ellmer, WHAT BUSINESS will be on those floating concrete bubbles?


    The first floating business wave is ocean related business, tourism, ocean food, energy. On the long run as space on land becomes expensive and more and more interference overloaded the dynamic pushes business out of population centers seeking interference freedom, space, mobility and resouces on the oceans…http://concretesubmarine.activeboard.com/t56680633/the-reasons-why-oceanic-business-is-the-next-big-thing-to-co/
    Finally fabrication sites, residential condos, all human activity that needs space will take advantage of the space available in the planets “hydrosphere” that counts for 99% of the habitable volume available on the planet. Space on land will need to be kept as a “wildlife reserve” to avoid further mass extinctions due to human activity. It is not feasible to asign more space on land to megacities. The only space that can be made available to human activity is the 99% kept untaped so far. We see floating LNG plants, floating tourism developments, floating seafood production sites, floating energy installations, floating minery, already, this is not “utopic” it is happening and it is unevitable. It is predicted that the 21 century will see more construction activity at see than on land.

    Concrete is made of things dug out of the land. There is not enough land to make enough concrete to move all of humanity to the oceans. And you keep giving dreams of 100 years or more from now, i keep asking about today or tomorrow. Some 80% of Australia is unpopulated, and there’s places in the usa you can drive for an hour and not see anyone. There’s no land shortage. Strangely, there’s some shortage of international ocean, there’s only two small spots in the Gulf Of Mexico that are not in usa, Mexican, or Cuban EEZ. And i can imagine the ocean floor will soon be off limits to everyone.
    Yet when i ask you practical questions of how one makes the proper mix of cement, or joining floating cement parts, or any hydrodynamic question about such massive amounts of floating concrete, or legal questions a seastead will face, you have no answers.
    I read two recent reports yesterday about hurricanes in the GOM, one from the usa military and one for oil platforms in the GOM, and both mentioned common 16m/50ft waves, and peaks of 28m/90ft. Since those were previously considered 500yr or 1000yr events, but they have occured several times in the GOM since 1995, i’d damn sure like to know what the dynamic water pressures are on various sizes and shapes. One report noted oil pipelines buried over 6ft in the ocean floor were scoured up and moved 2 miles (i have mentioned this before), tells me the bottom on the continenetal shelf, or at water depts shallower than 60m/200ft are too unstable and unsafe to put your submerged or floating concrete spheres. Even if the sphere survives, the inhabitants probably will not.


    concrete shell structures
    From what you comment here i asume that you will be surprised that floating concrete shell structures of 70m diameter have already been placed in the sea and on the seafloor and are performing there for decades without problems and decay as we speak. The ocean facilitates the construction of large concrete shells.
    All plans like “urbanize the Amazon” settle Australia ect. that have been up and moving forward vigourously in the seventies are now shut down as people notice that disturbing nature that way causes mayor trouble to the planetary ecosystem. We will need to “build existing settlements back” and give nature more room instead of “using up more apearently empty land” for human activities.
    A floating concrete shell structure like the one you see in the picture above can recieve a shipment of grocery anywhere on the ocean – Coober Pedy in the middle of Australia can`t that is oceanic mobility and the reason why almost all mayor human settlements are near coasts or rivers that facilitate transport.

    This is one of the reasons that make floating headquarters like Abramovic is using so elegant – you can not do business with the center of Australia from a Yacht but you can approach all mayor business centers on earth from sea without crossing anybodies border and ask your business partners to come on board for a meeting with a 3 minute boat ride from shore.

    So it’s only for billionaires, someone with money to burn 10,000’s of gallons of fuel each month, and pay a crew. Plus the $millions cost of the sphere or ship. It’s not happening here, there’s no reason to. This is really getting depressing, Ellmer. I don’t have $millions.


    Only for millionairs? Absolutly not! You can start with something small like this. You can try to get a permanent anchor permit as a bouy for this and promise to run and maintain the lights of a “reefmarker” to facilitate the coast guards work. This makes you a “desireable piece of infrastructure” instead of a piece of “undesireable development”. The picture on the right is my prototype. In your case i would not apply for vessel status applying for this status has a lot of downsides, especially when you are at very low budget and resources. There are “tons of ruling code” a vessel needs to fit in and keep your project inside that “code” is expensive and unconvenient – at least as far as i know Florida regulations study the Lozman case before you rush down the wrong “authority handling road”.
