Idea is to use a ball shape with HangingBallast to stabilize it. With a 30 food diameter ball you could have two good floors and extra storage space. Should be enough for a family and about the lowest cost possible.
This is very much like User:Vincecate/GeodesicVessel but with no stability from the shape of the structure.
The geodesic shape should mean you don't need as much, or maybe any, internal bracing. This can open up the inside space and make it cheaper to build.
Should be very strong, very stable, very safe, and not very costly for the amount of living space.
Could use small strong glass to make portals to let some light in and let people see out some.
The heavy things like batteries should be at the very bottom of the inside space (say below a flat internal floor). The building on top should be light so that even if the main hull flooded it would still stay upright.
If we could make a form for concrete this could be really cheap. In Anguilla they make forms for poring cisterns where the two sides of the form are connected together by pieces of metal which stay in the concrete. There is a way these are released from the form so the form can be taken off. I think a similar thing could be done to make a 30 foot ball mold work.
Steel or aluminum plates could be done with triangles making a geodesic shape.
- As long as the hanging ballast stays on it should stay upright
- Should have a gentle motion on normal days but significant response to large waves.
- Hard to imagine anything cheaper than this that has this much space and is safe in the open ocean.
- Sometimes functional things start to look nice after awhile. And not every one can afford pretty houses.
- Can make individual family sized units. Could have cable under a line of these so they floated together if you connected a sea anchor at one end and a large kite at the other.
- Since it floats up and down with waves like a boat, should be reasonable to dock a boat next to it.
- Free Floating
- Yes, could anchor also.
- Is small enough for one family. The shape could scale to much larger sizes. Geodesic domes scale well.
- Will move through the water easier than most seastead designs but not as easy as a ship.
- Very shallow draft for a seastead.
