We are working on a seastead design.

The goal is to design our seastead such that all the parts can pack into a single a High Cube 45 foot container which has:
   width 7.7 ft
   height 8.9 ft
   length 44.6 ft
   max weight:  62,000 lbs  (rated bouyancy at desired waterline is 27,500 lbs and we hope structure is enough under this that humans and their stuff can fit)

Above the water there will be a big equilateral triangle frame, 44.0 feet on a side. 
The triangle frame is also the wall of the living area and will be 7 feet high (floor to ceiling).
It will be enclosed and the whole inside the living area.
Around the whole outside of the wall, except where the dinghy is in the back, will be a 3 foot wide walkway and railing that 
is bolted on and has some diagonal supports from below bracing to the wall (so walkway is 1 food higher than bottom of the wall).
The walkway will have an aluminum grating that would let a wave pass through but you can walk on.
Also two doors on the back side,  one two feet in from left and one two feet in from the right side. 

There are 3 legs/floats/foils/wings/keels that provide the buoyancy, so it is a bit like a trimaran but with a very soft ride.
Each leg/wing will 14.5 feet long and have a NACA 0040 foil shape with 8.5 foot chord except that the last 0.5 feet of
the thinnest part will be cut short, so with foil does not come to a point at the trailing edge and fits within 8.9 feet
hight of container.  But the buoyancy is very close to that of an 8.5 foot chord foil.
Each of the 3 legs will be attached to the underside of the big triangle near one of the 3 points.
The center of the thickest part and going 1.5 feet in all directions from there will be within the area of the triangle,
but within that constraint, each leg will be as close to the point of the triangle as possible.
The legs will go down so that the lower half is in the water.
This makes for a bit of "small waterline area" similar like a small oil platform but one that can move through the water easier because of the foil shape.
It is not an extreme SWATH design as a 1 foot change in water level is about 1/7th of the total buoyancy, so still significant change.
The 3 legs will all be parallel with the blunt or "leading edge of the wing" side facing forward so it is lower drag when moving forward
than a typical cylinder on a semi-submersible platform.  
Each leg will be 50% under the water (so 0.5 * 14.5 feet) and the top 50% out of the water.
On the top half of the front of each leg, so the top half that is out of the water, will be a built in ladder.

The reason for these sizes for the triangle and legs is so they can pack into a container nicely and shipped to 
a shipyard anywhere for assembly.
Imagine the 3 legs end-to-end with thin/trailing-edge of foil up and leading edge down on the right side of the container.
So the right 3.4 feet of the container (width of legs) is used by the 3 legs.
Then the 3 frame/wall sections will be upright (so 7 feet high) next to each other along the left side of the container.  
I am not sure the width of the walls but if they were 10 inches wide then 3 widths is 30 inches and some extra is 3 feet on the left side.
There should still be lots of room in the center of the container for all the other parts.

Connecting the mid points of the walls both at floor and ceiling level will be structural beams that
make another triangle 22 feet on a side.  Then all the remaining spans will be less than 22 feet.
The rest of the floor and ceiling will be small pieces that are bolted in.

On top of the roof there will be solar all over.  With batteries and electric thrusters as the main propulsion system.

There will be 6 RIM drive thrusters of 1.5 foot diameter, one on each side of the 3 legs/wings about 2 feet up from the bottom.
These RIM drives will be all be fixed orientation to provide forward thrust.  It will use differential thrust to turn.
For slow movements in tight areas like harbors it can reverse thrust on one side and forward on the other to turn in place.

There will be a conduit/pipe welded to the back of the trailing edge to take electrical wires down to the thrusters.
There will not be any "through hulls" in the legs.  The legs will also have multiple
airtight compartments each for safety.


Behind the back near the center will be two supports going out and 2 ropes going down to a dinghy.
The dinghy is a 14 foot RIB boat (deflated for shipping) with an electric Yamaha HARMO outboard.  It is sideways against the center of the backside of the living area.
When the seastead is moving forward the dingy is shielded from the wind by the living area.

On the lower part of each leg will be several bolt on heave plates.  These will help dampen the response to waves.

About 25% of the displacement will be for LiPo4 batteries which will be put low in the 3 legs.
Each leg will have its own charge controller and inverter so there is triple redundant power on the seastead.
Also, the thrusters for a leg will get power from that leg's inverter or batteries.  So
the 3 pairs of thrusters will have independent failure modes as far as power.

When the seastead is going to be staying in one place for awhile, we can put down 3 helical mooring screws and give the seastead tension legs 
so it becomes nearly stationary when parked.  Near each corner there will be a pair of helical mooring screws with a motor unit between them.
We only plan to do this in the Caribbean where tides are very small and in protected places where the saves are small,
so pulling down 3 feet will be sufficient to never go slack.


Two seasteads will be able to connect together with a walkway, one behind the other, so that while underway 
people can move between seasteads, enabling a real community.  The two computers for the two seastead will both work thrusters
to minimize the movement of the walkway, particularly when warned that someone will be on it.





I think that some well engineered single family seastead, perhaps something like the idea above, can have a huge
impact on the world.  In the same way that the engineering of the printing press, the Internet,
Bitcoin, and AI has had a profound impact on the world.  Each of these engineering solutions
gave more power to individuals and removed some from "the rulers".  I think that once we have a good
engineering solution for single family seasteads, they will result in a similar increase in
power to the individuals at the expense of "the rulers"i, and so will also have a profound impact on the world.


I believe that most of the world currently has governments that so disrupt their
economies that it is much harder for people to prosper than it should be.  The total fraction of an
economy that is government spending (with all levels of government) is really high.  Governments get
money by taxes and fees, but also by printing money.

If someone moves onto a seastead and changes countries often (perpetual traveler idea) or stays in 
international waters, they can avoid most of the taxes most people have to deal with.  

Many people could be much better off by moving onto a seastead.  After this starts it will become
clear how much higher a quality of life someone can have by moving to a seastead, so I think
the idea will snowball or go viral.   In some sense if people can't leave their current country
they are not really free.  In practice many people can't get permission to permanently move
into another country.  So in practice most people are not really free, they are
"tax slaves".

If people are free to leave then governments that are really bad will lose lots of good people
and those that provide a great place to live could gain a lot of great people.  So you could
get the benefits of competition between governments and so governments could have market
forces pushing them to improve (which we don't see much of today).  With seasteads the 
impact of bad or good government changes could be quickly seen as many people could 
far more easily "vote with their feet".  If people can easily pick which legal system
their home is under they will have fare more control over their destiny and freedom than most people do today.

Ever time you have to buy something, say gasoline or electricity, from someone else it
provide an opportunity for governments to tax the exchange.  So the more self sufficient
you are the less tax exposure you have.  If you are out in the deep ocean and 
making your own electricity, making your own water, and catching your own fish,
grow your own sprouts, you have inherently have very little tax exposure.

Historically homes have been tied to a geographic location and governments have covered
geographic locations.  With seasteads the home becomes mobile and you can change what
government and laws you live under.  It is a real game changer.

To begin with single family seasteads can move around between countries often like yachts.
As we get more some will pay for the rights to do tension leg anchoring for extended periods.
As we get even more some will make floating communities that move around.   And at some
point there can be a community that stays in international waters.  So it can sort of
grow organically and evolve over time to be more independent of existing countries.

Please  expand on the above explanation of the "why of seasteading",  the motivation, and potential impact of seasteading.  
Please try to explain why someone could be very passionate about seasteading as a possible solution to a big problem in the world.
But try to explain it in a way that someone not familiar with the issues and seasteading 
could understand why it could be a powerful solution that has a big impact on the world.
