    Biorock grows on the electrodes as CaCO3 and  MgCO3, the way I understand.

    At deeper levels of the ocean 1000m to 3000m (1000 m = approx = 3000 feet, 3000 m = approx = 9000 feet)

    the pressure is much higher then in the upper layers of the water column.


    Factors determining chemical reaction rates can be significantly different at deep levels, compared to

    the upper layers:


    Pressure is much higher.  Temperature is lower. Concentration of reactants can be different.

    At higher pressure the dissolved CO2 level may be much higher.


    Just like in a soft drink bottle at the time of opening the CO2 escapes because of the pressure is lowered.


    A high concentration of CO2  would favor the formation of HCO3- and CO3= ions.  The higher concentration of

    these reactants can speed up the growth rate of biorock.


    There might also be other effects of pressure on the reaction rate.


    That would be an interesting experiment, to sail out there and put two pairs of electrodes in the water at significantly

    different depths and observe the rate of growth of biorock on the electrodes.


    Well, this is how I understand, and this is how I could write it down.

    The watercolumn:

    Ocean Law Panel Q&A at the Seasteading Conference 2012

    the video at 7 min 05 seconds:
    Myron Nordquist said about the International Seabed Authority:

    “… but, they only have resource jurisdiction out there. And so they don’t have
    any rights in the water column. ”

    So in the water column, if nothing is touching the seabed, and it is outside of the
    Exclusive Economic Zone of any country, than nobody has jurisdiction.

    Biorock can be produced out there, and nobody has jurisdiction over that activity.

    Video at 29 min 15 sec Mr. John Briscoe quotes pres. Ronald Regan:

    “In the areas beyond national jurisdiction in that area deep seabed mining is a
    lawfull excerise of the freedom of high seas and open to all.”


    And I ‘imagine’ the water column is even less of an interest of regulation.

    “… clams, right out of Jules Verne, 12 feet wide …”


    I think what he means here, is that there are very large clams and seashells at

    extensive depths of the ocean.

    And the genetic material could be different of those clam, but
    it also could be that these 12 feet wide clams can grow shell
    faster and larger at extensive depths because of the special conditions
    at that depth.

    Biorock was originally a research about seashell formation, and how to
    artificially produce such a thing.

    If natural biorock can grow faster and bigger, may be, artificial biorock can
    do the same.

    And I guess, this is a nice hypothesis, and I probably should quote more data
    about this. I just also wanted to indicate how some information can stimulate more
    ideas and directions.

    And still, this is how I could write this down.
    If you get something out of it: God bless you.

    Spark, thanks for this research.

    Now, some questions you may be able to answer.

    What is the optimum distance between cathode and anode?

    Do you know a quick & sloppy way to estimate how much current would be needed for a given size structure? (I assume surface area is the main factor)

    I know seacrete/biorock that grows more slowly is denser and stronger. Consider a framework of rebar or steel pipe that I want to cover with a dense, slowly grown layer before I speed things up. What voltage/amperage do I want for each phase of that growth?

    I realize these may be questions that nobody knows answers to yet.

    Again, thanks for your work.
