We are working on a seastead design.

Above the water there will be a big triangle frame.  The
left and right sides will be 70 feet long and the back part of the triangle will be 35 feet wide.
The point opposite the 35 ft side is the front.
The triangle frame will be a truss structure that is 7 feet high (floor to ceiling).
It will be enclosed and the whole inside the living area.  Lots of glass to see out.

There are 3 legs/floats/foils/wings that provide the buoyancy, so it is a bit like a trimaran but with a very soft ride.
Each leg/wing will 19 feet long and have a NACA 0030 foil shape with 10 foot chord and 3 foot width.
Each of the 3 legs will be attached to the underside of the big triangle near one of the 3 points (but the total top of the
leg will be inside the triangle) and going down so that the lower half is in the water.
This makes for a "small waterline area" similar like a small oil platform but one that can move through the water easier because of the foil shape.
The 3 legs will all be parallel with the blunt or "leading edge of the wing" side facing forward so it is low drag for the seastead to move forward.
Each leg will be 50% under the water (so 0.5 * 19 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.

There will be 6 RIM drive thrusters of 1.5 foot diameter, one on each side of the 3 legs/wings about 3 feet up from the bottom.
These RIM drives will have the flat sides toward the front and back of the seastead.

On top of the roof there will be solar all over.

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 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.
Also behind the back on the left and right of the dinghy will be a deck that is 5 feet wide extending beyond the back of the triangle.

There are 3 stabilizers that look like a little airplanes, one attached near the back of each main seastead leg.  
The little airplane has a 12 foot wing-span, 1.5 foot chord, the body 6 feet long, and the elevator has a 2 foot wing-span and 6 inch chord. 
A small actuator makes the elevator angle up or down so it can adjust the angle of 
attack of the main wing of this stabilizer without needing a large actuator.
This is really the "servo tab" idea.
While the thick part of the leg is 3 feet wide the back where the airplane will attach is very thin.  And to get the airplane's
center of lift to balance on the pivot a notch into the front/center of the wing only has to go about 25% of the chord of the wing.

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.

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.   





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, I think that once we have a good
engineering solution for single family seasteads, they to will 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.

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.
