Ocean, i agree completly with you, Joe Blow his financial capacity, his decision making processes, how he will compare us with other “create living space for your family” offers, this is the key to make it happen – if we can not make a good offer to him – massification of seasteading and a social relevant amount of seasteaders will not happen.

So how do you feel about that scenario – Joe Blow – buys a “piece of space” from a floating development managed by seasteading inc, the cost is very low as the price per squaremeter out on the water is not competed as “land” woud be. He recieves a container of floating HDPE elements from xns. He assembles them to a floating form in one afternoon. Then he casts a concrete shell on top of the form recieving a mix truck on a barge organized by seasteading inc – within a week or so Joe Blow is mounted this way.

He has not to be a pioneer as the engineering is worked trough by the engineers of seasteading inc and the permits are done by the development company. John also counts with a favorable “floating homebuilder credit” from seastead inc.

Now as John has created his own parcel of land he can build any kind of structure he likes on it – seasteading inc. – recommends dome houses and similar structures that can take a massive water wash. They rent airforms, sell modular housebuilding sistems, offer container houses, and a wide range of other options – all in range of a normal pocketed housebuilder.

Johns floating house vision ends up to be this:

but it could also be something like this:

Or something open water capeable like this:

or something like the floating and submerged shell structures that we build (see earlier in this thread)…

Seen from the air the floating district promoted by seasteading inc will look very similar to this:

just it contains “houses” mixed with boats…

Spars have limited area at the water-line, but behave well, such as FLIP… The ONLY time FLIP had a problem, it was anchored…

Never be afraid to try something new…

thats a cool idea. lots of space below the surface and a little bit of room to romp around on a pleasant day outside.

The concept of of flipping a space is good for a oceanographic station where you just need to flip a few chairs and a small table but for big and complex living spaces it does not work – you can roll over a small sailboat – not a cruiseship – a city needs to stay on even keel – all the time – not only sometimes.

That leaves flip spars for “permantently flipped concepts” you tow the spar out flip it ONCE and it stays flipped. Siemens Wind turbines, Oil Rigs like Draughen and Perdido do that. Sea Orbiter plans that. The general idea lift the important things so far above the ocean surface that waves can not reach it. The problem is the spar to do that is a structure that costs a lot of money and the “save place” on the top is ridiculusly small and expensive to serve for housing purpose.

. . . .

The best is probably Sea Orbiter it combines a underwater living space with surface part – if you want it is a spar that went halfway to being a snorkel boat…

You could increase the mobility and efficiency by making the underwater part blimp shape and the “stick out part” smaller to reduce wave and wind attack surfaces . What you end up with is a submerged living space bubble that gets air and access from the surface by a tube – call it a snorkelboat.

for the need to be mobile while seasteading. While those ships have to go thru those storms due to contractual obligations of being in port @ a certain time, a seastead won’t. A floating mobile seastead can easily avoid such storms by changing course towards calmer waters, anytime.

I can definately postulate that a mobile seastead could operate in calm(er) seas at all times.

I don’t know seems to be a expensive and risky strategy to depend on fast mobility to avoid storms – what happens when the engine is down and a storm comes in. Being permanently at sea and always on the run to avoid the storms…

Why not build something that can stand the storms in first place…

A concrete shell for example

If we are talking about stationary seasteading, NOT anchored and NOT floating, but permanently built from the bottom up on a shallow seamount or in a bank somewhere, I totally agree with you. You would built solid concrete shells that would last forever. Done deal.

But, if this is the ultimate goal, then why not just buy a deserted island somwhere, and just build on it? It would be much cheaper than building the whole damn thing from scratch, for sure.

If we are talking about stationary anchored, I have big doubts that anything will hold in place or survive a categoty 5.

Maybe the current on the bottom will stirr the sand (mud, etc) and your anchor will drag. Or maybe not. Maybe your chain will broke (remember, your are built heavily and your inertia is high under those conditions). Or maybe not. Maybe your deck won’t hold your anchor cleat(s). Or maybe it will. Maybe you’ll take a big one over the bow and develop a bad leak on the main deck and start taking water big time. Or you won’t. Etc.

To many “maybe’s” to let life and property ride on,…in my book. Are you ready, as a builder, to sign up on that project, in good moral faith, when you know that 250 people will live on it, permanently? What are you gonna tell that captain who is supposed to assume command when asked: “How do I avoid a storm in this one?”. Because if you say “No worries, bud, is build to last.” you’ll have a hard time finding a good captain. Do you think Lloyd (or anybody else, for that matter) will insure you without an engine. I doubt it. And good luck finding investors who will give you money if you cannot insure their assets.

And for what? To save 5% off the total cost on the price of 2 good engines? My oppinion, anyway.

Because every square inch of land on the entire planet is owned by some government. You can buy an island if you like, but it will still be owned by the country you purchase it from, with it’s laws and regulations. The only way to be completely free…or even have a chance at being completely free…is to build something new in an unclaimed area. That means international waters.

i think i made it clear before. my islands are NOT free. i personally like money, and the best is when u worked hard for it, the customer knows u worked hard for it and provided them wth a lot of value for a decent price and they will give u that money and still be grateful as hell that you provided that product or service for them. my painting customers love me like crazy. the number of people who i worked for that have NOT served me a full course meal at their table is less than 10% of my customers – not a joke. these peeps are happy to give me their money, and grateful about it. they know that my product constitutes a major improvement in their life that can last and last for many years.

ohhhhhhhh PJ calling PJ. i know ur listening…

In practice, you’d be better off buying a 400 sq acres tropical island with sandy beaches, nice coral reefs around it, lots of coconut trees and good farm land from a Banana Republic, bribe on the top, keep your mouth shut regarding “sovereigity” and do whatever the heck you want,….rather than build on the seabed somewhere in the international waters, yell “sovereignity” all the way up to the UN, just to end up being evicted by the same Banana Republic since “you are in their EEZ” (read – “Get the fuck out of here, you should have paid up for one of our islands, stupid”)

PS. “Completely free” is just an utopia,…no such thing, in real life.

how does this disclosure of your intimate love relation with money and other people feeding you free food has anything to do with the subject at hand? Just curious :::)))

i just basically meant that, despite the current economic environment, there are people who have considerable amounts of money, and the rest of us should a least try to make products and services worthwhile for them to keep spending it. and thats how i look at this seasteading business.

Building structure on an island is not more economic than building structure afloat. On the water you don’t need to buy a building lot, and you can move heavy modular things around very economic. You also can get materials (like cement) shipped directly in container from china, with no taxes and no land transport cost.

In fact my favorite scenario is buying a beach or just a “floating right in front of a beach” to stay third party interference free, in the range of 9 on the 1-10 scale but build afloat anyhow. What concerns building a house on a tropical beach and building something afloat in a tropical country i have done both and i would prefer afloat for a lot of practical reasons (see more here) among those jejenes, administrative hurdles, and breeze.

Some of the general reasons why and how you choose a location is discussed on the Seasteading Caribbean select loctation thread.
