    actually i think i figured it out, yep. attach the hydroturbine to the mooring block and tie the electrical cable up to the mooring cable. for people who live further offshore it wont be a problem but for those who need to shuttle back and forth this will make a solution.

    well there’s a technical challenge for ya Emmett. im completely fuckin lost here. when the tip hits the floor at 100′ the top of the tree barely goes under the water at all…

    100′ is a normal water depth (in a lot of places) at 20 miles off the East Coast, USA. looks like the Bergstead is a no-go there unless somebody comes up with a real solution. I think it might be deeper off of California but they dont get hurricanes. i need hurricanes. i could use a double strength hurricane right now.

    im back home from Fort Lauderdale. and im ready to start working again on this model. i had important phone conversations with several forum members over the past week, including Jon (jtg426), Octavian (Oceanopolis), and Emmett (Mad Dog Tannen). i have an announcement to make: im moving to south florida to work on seasteading. i need to rip out a couple walls and replace the drywall to solve a mold problem at my condo b4 i leave delaware (hurricane irene blew some water where its not supposed to go). at present i expect to be in florida in 6-8 weeks. ill still be working on the new model the whole time. Jon has great ideas on how to put together the organizational aspect of our collaboration. Emmetts frickin awesome on many levels – u wont believe how well-spoken he is.. Octavian… will come around – if we have something going that he can help out with i know he will. Pastor Jason is always prepared to pull a fair share of the weight. And of course there’s Wil, who’s not in the States but regardless of whatever contribution he makes going forward, the truth will always be that this design concept was influenced by him from the start.

    i got a response from a guy i emailed before. i found him by looking for r/c submarine ballsast systems. the guy i found is the best one i could find. he builds and sells them. and they can be very complex. what he said is that a simple ballsast system would be best for this model. one valve oens to simply let the water in. a vent up top transfers air to and from the surface. and a simple bilge pump is installed to pump out the water and return it to positive bouyancy.

    im goin to bed.

    Wow awesome man! should make an IRL get-together thread. Whereabouts in south-florida is this Seasteading Intentional Community gonna be happening? I’m assuming Conch Republic.

    We’ll probably at least visit or mayhaps even join for a time. I have a feeling it might be too-hot in florida *shrugs* but who knows, being vegan kinda makes hot-weather seem okay. Can get bulk avacado’s from nearby mehiko! I’m sure my partner would love that.

    Jon has great ideas on how to put together the organizational aspect of our collaboration.

    post a thread, we can all collaborate.

    hmmm, seems I wasn’t mentioned…. well it’s okay. I love the mountains, so we’ll probably continue heading to the west coast after our visit…

    nice, might get something like that for the dinghy, after we get it down the river and install a hatch/rudder/windows/propeller.

    The name of the topic forum I started is in the subject line… Please feel free to stop in, weigh in on the idea(s) presented and/or just say “Hi”…

    Shredder

    Sorry to hear about the mold issue and water damage. I am sure you can take care of it though. I will be contacting you…

    Everyone- else

    Working together on a project, even if it is not the one closest to your heart, will only benefit everyone. I am not pushing a platform idea… I am not pushing a build location… I am not pushing for a float location… I am not asking for money… I am only asking that people who are passionate and dedicated to Steading the World’s Waterways come together to discuss the formation of a committee/business (the actual hierarchy of said group and the build project/location/float site will be decided by the members… not me!) to invest thier time and efforts in pursuit of ONE goal.

    Thank you

    just checkin in w a quik update. i cannot wait to build and test some more concrete models. im about half done refurbishing my condo. even tho i just had about 2.5 weeks of no work a short time ago, i suddenly got about 2-3 weeks worth of new painting jobs. so i think after my condo is done im gonna live with my parents for a short time and get those other jobs done. the moment it dies down i cant wait to go to florida. i just want to earn the extra money to pad me in case i should need it.

    even while im doing the other painting jobs i’ll work on assembling the forms. i actually started already. i wish i was testing more models right the freak now! but money is such a stubborn need.

    Sam try reading over this thread a little more closely. seems like u might have missed some key qualities that this design has. its intended to ride out a hurricane, not on the surface, but below the surface where it is calm. no need for a spare crew, and really u could get away with not bolting stuff down if u wanted to. this plan has a long way to go before its ready for a full-scale test. i plan to make several more scale models. the next model will have a working ballast tank and a pump.

    Shredder, you said you want to feed people breakfast at sea? How tall (total) are your side walls? What is their construction? You asked me about a different design to take on a hurrican/cyclon. As for the design pictured, it looks like a house boat you want to submerge for rough weather. I think it would be cheaper to modify a used floating barge if you like that design. Design the top the way you want,the bottom the way you want.I think you are going to have a lot of issues/cost with sealing and submersing your unit. You could ask ellmer about that.The design formentioned would work great down in the islands/Belize. I am still trying to uderstand the pyramid anchor with four cables? Dangerous in rough waters. As for the weight of it,you could change it to an alluminum design and have a remote ballast system for increasing /decreasing the weight in the pyramid. You could even run the two in tandom.

    this picture explains how a very simple ballast system works. can anyone explain why this diagram has a flood valve?

    The pendulum itself will be a sizeable chunk of your ballast. The baseline ballast, if you will. I think you can take all of that space in the entire upper portion of your current ballast design and reclaim it for mechanical/engineering spaces and provisions storage.

    For coming to shore, you’ll want to raise the pendulum. The ability to raise and lower the pendulum will also help with your general concerns of it hitting the bottom. The power of the pendulum to stabilize the bergstead comes from its attachment points at the extreme ends of the base, however to attempt to use pulleys or capstans on those corners will put undue stress on the structure as the pendulum is raised and the angles get more acute.

    I would look at using centralized capstans to reel in the four lines, and mechanize the pulleys on the corners to ride on tracks that go from the corners to the center. When raising the pendulum, the pulleys would be moved to the inner positions, which make the lines pretty much vertical. The pendulum’s stabilizing effects will be reduced, but it will be easier on the mechanicals to reel it in. As the pendulum is lowered, the pulleys can be moved back to their outer positions to regain stability.

    Perhaps, instead of dead weight in the form of crappy concrete, the pendulum could contain the sealed battery bank with power cables running up to the bergstead’s machine room. That would keep the pendulum, but make it pull double duty and regain some space inside the bergstead. It would also place the weight of the battery bank lower in the overall structure for added stability overall.

    hey Ellen,

    good to see u again. i used a quantitative spreadsheet to determine the best balance of pendulum size vs ballast water. as crazy as it may seem, i need all of that pendulum and all of that ballast water to reach neutral bouyancy (according to my spreadsheet). it does seem like a good idea to put the batteries and maybe some mechanicals inside the pendulum. problem with the batteries tho is they sometimes need to be replaced. even if i built the casing for the batteries right into the concrete and installed the anodes/cathodes/ and water right inside there, eventually the cathodes will have to be replaced. so there’s a question as to what is better overall?

    I like the design. I believe that you’re using the four cornors design for the anchor is a good Idea. If I understand it, if the ship starts to tip one way it pulls on those cords more. Seems it’d be better than a center weight I was using for an idea. (Hi I’m new by the way :D )

    Now here’s a question. Remove the sinking part of your design, go somewhere with better weather, would the design still be fesable with alot more room to it, dirt and growing space on the top? I don’t know what programs you use to test these, I’m no engineer, just an analyst. :P In case of bad weather if you had 10 of these and 9 of these (without the submerging) if they all linked tightly togeather I’d think with the exception of HUGE storms they’d probably fair rather well.

    im thinkin about / leaning towards using hardi-backer this time for the ext. walls. the project is an even smaller scale than the last one and the walls are really thin. “half inch” hardi-backer is actually 0.42 inches thick. i needed 0.39 inch thickness to make it accurate, so its very close. the problem, though, is that the hardi-backer material is actually about half the weight of typical concrete. i think the weight of the battery and ballast pump will help offset that problem. if i need to i’ll add some weight to make up the difference.

    thanks for the remarks Chad. look for the ARTWORK thread, page 4, to see my design for connecting these structures together. i’ve never believed in “adding dirt on top”. if someone has the power and influence to buy one of these islands, or even just pay for the materials needed, they’re probably not a bum. they will have money to buy food and store it. these islands are not really intended to be used more than 20-25 miles offshore. its part of what we call ‘incrementalism’.
