The Seasteading Institute

Progress has been made in the genetic understanding of why barnacles attach to surface. This might lead to a replacement for a medetomidine drop system for keeping critical submerged surfaces free of barnacles.

For garunteed reliability,

as passive system that always works

must be applied for any hull garden management.

For seastead islands,

as a source of food and materials,

barnancles and other biota are exellent.

For speedy watercraft,

a passive biofouling retardant,

like would be most effective.

though actively cleaning is possible,

regular drydocking is also an effective method.

Biorock, baby!

There is no fate but what we make for ourselves. Each to his fate.

Exactly. Even better if we can use something cheap, like wood, for the seed material.

rocks, like limestone or coral,

for making cement or concrete,

are much cheaper than wood.

wood rots and wood burns,

but maybe we could use it to replace steel,

it would certainly be much cheaper.

though wood tends to expand if it gets wet,

anyways here’s a discussion on bamboo reinforced concrete:
