You know if we are already going through the effort of transporting & stacking dirt vertically for these things we might as well go all the way and integrate them into the pylons of offshore wind turbines, which'll guarantee them a viable support structure, an infinite amount of available seawater & more than enough power to desalinate it locally. Heck, the harvest logistics means it'll give fishing boats something to do off-season too.
