    Some opinions I found on the Internet:

     

    Polystyrene foam is really just polystyrene have been processed to contain pockets of gas (foam). Applying acetone to Polystyrene foam does not melt it, but rather dissolves the material.  It is  spectacular when applying acetone to Polystyrene foam because the gas pockets collapse, the solvation is quick  and a large volume appears to dissolve into nothing.

     

    Though it wouldn’t be easy to accomplish in a home lab, the acetone/Polystyrene foam solution could be processed and re-blown into a foam.

    So, the styrofoam:

     

    Well, better call it on generic name: polystyrol.

    I got polystyrol chips from packageing material before it was dumped in the garbage.

    And I got some seawater. I tried to coat the chips with seawater by immersing them

    in a cup. I drained the cup and put it in the microwave oven with the chips in it.

     

    The polystyrol chips did not melt together.  I tried increasing the boiling point of the

    salt solution by saturating the salt solution with table salt. The chips did not melt.

     

    There might be pressure to increase the boiling  temperature of the  salt solution to the

    melting point of the polystyrol. It would be like a pressure cooker.

     

    I got polystyrol chips for free, and salt water for free. I did have a microwave ove.

    So no special equipment was necessary.

     

    I find this interesting. I feel it is more meaningful than watching TV, or playing

    video games. (video games can be still better than TV).

     

    I am  going to read the patent, and other things, and I will probably figure this out.

    I will write about it here.

    I think; the foam structures coult be joyned in water.

    Smaller, identical cross sections of a boat-like structure could be made.

    The front (bow) and the end (aft) would be identical to each other.  Midsections

    parts would be identical to each other too.  So there would be two different parts: end parts (bow and aft)

    and midsection parts.   I will draw some pictures too. 

     

    Each section would have some reinforcement in it and ballast.

    Each section would float similar by itself and when it is joyned with other sections.

     

    There could be pipes across the sections that would align, and  tensioning

    ropes would hold the multipe pieces together.

     

    Right now this is how I can describe it in words.

     

    More later;

    Hi;

    Yes, I like the biorock idea too.

    In my initial comment I wrote:

    “(or cover the foam with chicken wire and grow biorock over it)”

    And I think the big advanteg of biorock is that it grows even after it is quite thick.

    Or, by turning off the electric current the growth stops, (I guess)

    And it is mentioned somewhere, that if the biorock growth gets damaged, the new growth prepares

    the damage.  It sounds interesting.

    Using recycled polysytrene beads to make a consolidated foam structure:

     

    ————————————————————————————————–
    Polystyrene bead expansion process
    Abstract
    Polystyrene beads or beads of other thermoplastic material are expanded to a consolidated foam
    structure in a hollow cavity of a marine float or other structure by providing the beads with
    a uniform coating of a saturated brine solution or other aqueous solution of water-soluble salt
    and exposing the solution to microwave energy to boil the solutioln and thereby heat the beads
    to cause expansion and fusion to a foam structure.

    It is a patent: http://www.patents.com/us-4765934.html

    There is polystyrene plastic pieces floating aroud on the seas as garbage:

    http://en.wikipedia.org/wiki/File:Polystyrene_salvaged_from_the_sea_-_02.jpg

    For a seastead floting structure, these polystyrene plastic pieces could be collected,
    ground up to make small pieces, and the bead expansion process may be used to make a
    consolidated foam structure.  The nice about it is that the bead expansion process uses
    sodium clhoride water solution. That can be seawater or concentrated seawater.
    More about polystyrene in wikipedia:

    http://en.wikipedia.org/wiki/Polystyrene

     

    The drawback of polystyrene that it burns, and fire hazzard is high.

     

    Thought it is used in architectural structures:

    And large structures are made too:

    Going into things like that, there are going to be dead bodies sooner or later.

    (just like in mainstream medicine) Better to have an explanation ready.

    Further more;

     

    If there would be, let’s say, a 50′ long steel reinforced urethane foam structure with a ferrocement coating.

    May be we could call it a platform.   If this platform is anchored in international waters and no human is on it,

    would anyone sink it? What if it is 25 miles from shore?  What if it is 201 miles from shore.

     

    First of all it would be a difficult task to sink it.  If a platform is cheap enough may be $1000 or less, and there are

    more of them just left out there? What would happen to those?

     

    If there are many of these structures out there what would small sailboats gather around them?

    What if these platforms built bigger or smaller?

     

    It is like in the song Alice’s Restaurant:

    If there is one, than the idea is dimissed.

    If there are two, than it can be dismissed with a derogatory comment.

    But , if there are three!!!   Than it is a movement!

    Anyways;

    Seasteading would speed up if the platforms could be reproduced at sea.

    People on one platform could make and identical reproduction of the platform using materials found

    at sea.  This might be difficult.

     

    I wrote about Platform Zero. So I think right now many of us are at Platform Zero.  No platform.

    I would like to call the first platform, or the first stage as Platform One.

     

    So, Platform One probably has to be produced or built at land, and launched and towed to position.

    Production on private land can be done without permits, I guess.  But launching and towing it to position

    would probably involve others and authorities, who/what can say NO.

     

    May be producing parts of Platform One, and loading the parts on legal vessels. Then to take the part to

    position that is beyond jurisdiction of anyone.  The parts could be put to water or launched and assembled

    in position.

    What kind of boat are you planning to buy?

    I could grow mangrove font of my boat in the dock.

    I let you know
