    "My submarine prototype - which i obviously did not test to destruction depth - has almost exactly the double diameter / wall thickness as troll - means it is double as strong and may have a destruction depth of 1212m" ​


    Hmm, what about a test (DNV/ Lloyd witnessed...?) to 1200 m? That would stop the arguements..

    I'm not that morbid, so I'd prefer an unmanned test, but I'd like to have a camera aimed at the designer/ builders face.... just in case to load on the wire suddnly alters rapidly, one way or the other...:D

    The 18 meter sub has a diameter of 4.3 meters and a shell thickness of 34 cm.

    An unmanned test would spoil all the betting. Someone shoot that party pooper

    I stand corrected. I was seriously out of depth with my post yesterday.

    BUT that implies identical layup, reinforcement, curing time, same concrete...
    or better.....

    And no windows, that weaken the strength of the hull.... No opening for any hatch, too... which makes it a bit impractical...?:confused:

    It's OK. The owner/builder finishes plastering from the inside....

    can we get back to the merits of this idea of a concrete sub?

    can someone remind me of what they are, i forgot

    I think the main merit lays in the inventor doing the test

    I have followed Willmer for 4 yrs. Apex is good to question. But is not the ultimate goal is to succeed in this project. No one including apex is willing to put up the testing dollars of constructing destroyable subs and sure there are concrete compounds that are 5 time stronger. but is this man of vision anything less than Orville Wright that had many aspect of flying incorrect. By creating one sub for a costumer is not a profit making adventure. This thread should be dedicated to progressing this technology. All the attacks are useless in helping this move forward. I want a sub that that can take 50,000psi economically built but no billionaire is offering an X prize to do so. So criticize as you may you aren't helping to advance this goal. I imagine a hull of multiple spheres with the new concrete materials can do this. I suspect that people like apex want to stop his research proved by his inability to come up with innovated ways to help Willmer surpass his dreams, because I've not seen one creative idea from him to help this progress. People lets dream to get this done and a compressible substance like concrete, ceramic that gets stronger under pressure is the way to go. Willmer I'm in San Fransisco and would consider it a honor to help your new sub along with any labor help you need as I would have offered to the Wright brothers.
