The Sea Foam Colony represents the ultimate form of non-diamondoid marine construction, vastly expanding the potential scale of structures through extreme performance while also providing a solution to the many dilemmas associated with the use of free-form organic design. SeaFoam is an idealized material that is projected to be produced as a result of current trends in the development of masonry technology. It is a recyclable foamed variable density geopolymer homogeneously reinforced with carbon nanofiber, producing a light fire-proof self-insulated and buoyant material with -at a given density- greater compression strength than concrete and greater tensile strength than steel at a fraction of the mass. It would be employed with a combination of production-on-demand material mixing, robot
