A Practical Beginning

No, I haven’t tried it yet. I’ll eventually get around to it. However, I can do the same thing with Blender.August 10, 2011 at 7:05 am #14606
http://www.tedcom/talks/anupam_mishra_the_ancient_ingenuity_of_water_harvesting.html Schredder, just add giant sized water tanks under your bergstead and use that roof for collecting rainwater to fill in the tanks, added mass will be good for stability and in a berg like ‘my work II’ the are of roof is more than enough to collect drinking water for a large family yearwide, with proper engineering the cost of tanks wouldn’t really be soo high. It is an off topic link but i just wanted to show how efficiently rainwater can be collected. Desalination isn’t really a must for starting seasteads unless they are intending to harvest the minerals they filter in some way.August 10, 2011 at 7:34 am #14607
Starting seasteading, our expectations from seasteadings here are mostly different so starting would be different too probably, for you problem is engineering, for someone else(most if not all of us) it is funding, for me the most important subject is location and legal restrictions. I wouldn’t want to work(engineer) and fund a seastead that might end up being constantly abused by local navies or even pirates. Thus i’d go for buying a means of naval transportation plus a semi self-sustaining underwater habitat, i think it’s engineering challenges are far less than a seastead, safer and more exotic. Instead of modules that are lashed to create floating cities i’d rather be in modules interlocked to each other in three dimensions to create a solid structure eventually forming some sort of platform or an artificial island. I’ll visit many east/south african countries in coming two months including somalia, kenya, tanzania and mozambique for business purposes. If all goes well(business) i might visit mauritius and saya de malha bank. That place is probably the dream of many seasteaders (though mauritius’ claim on any emerging island stuff gives most of us the creeps) i’ve been researching on indian ocean for a long while there are many spots on saya de malha bank that are protected from tsunamis and rogue tides due to extreme shallowness and massive area of the bank. I just wanted to point out that not whole ocean is dangerous, there are many spots outside of any national jurisdiction but still quite safe when compared deep oceans. Since your model is also not really a mobile type i thought you too might check it out and do a little research on shallow areas.
Also wanted to show my sadness on seasteading in this thread, as seasteading enthusiasts we are always trying to use already existent methods in innovative ways (though we somehow don’t prefer innovative ways since they are not tested and proven in large scale etc) and we never try to approach stuff from basics, take seacreate for instance, we proved it isn’t feasible(presently, with current methods) in many threads yet it saddens me to see people get angry when they hear the mention of it lately, seacreate and such biomimicry methods are actually feasible in theory but not in practice (i can prove the theoretical feasibility) so instead of trying to invent a method which is feasible in practice we simply eliminate the word ‘seacreate’ from our literature. Even stupid mollusks/nautilus can do it yet we can’t, i think we should focus a bit more on the subject, countless researchers are trying to understand biomimicry and there is more funding to it than we think, please don’t approach biomimicry with aggression and let people share their knowledge and thoughts.(this last paragraph was a little unrelated to subject, sorry for that)August 10, 2011 at 1:16 pm #14613

I believe that a seasteading start up will develop somehow along the 8 axes described below.
The catamaran float / The plate float out / The real estate squaremeter deal / The Captain Nemo float out / The bubble hotel / The current turbine / Breakwater lagoon marina / Oceanic port city design /
For me it is obvious that concrete will be the building material to start with – but i agree completly that we should not rule out any material or any technique – especially seacreate can and will have wide applications at least in underwater repair of the the structure as it is clear that there will be no chance to move a seastead to drydock – as ships do.
If we envision seasteads as structures that have a intense economic practical interchange with the ocean – artificial reefs, breakwaters, docks , will be part of the game – seacreate will have a place there for sure.
It might be that at the current development point the tech properties and economic feasibility is weak – but your argument that a stupid mollusk like Nautilus can build a shell that stands 800m waterpressure (more than a modern steel sub that costs a billion dollar and implodes at 600m ) is absolute correct.
So there is obviously much terrain to explore and room for impovement with great potential waiting to be discovered.

Correct me if I am wrong, but Nautilus adjust their buoyancy by moving gases in and out of their shells. They don’t implode at depth because they maintain an equal pressure inside the shell as what is on the outside. If they evolved to maintain a higher pressure of these gases inside the shell, they would be able to go beyond 800m. The shells don’t withstand the pressures based on structural strength, its a balance of pressure.August 28, 2011 at 3:50 am #15023

Nautilus features a pressure resistant shell, means the structue resists the hydrostatic pressue not avoids it by equalizing.August 28, 2011 at 4:15 pm #15033
Even then, if you look at the inside of the shell, there’s no real usable space.
