    Bioengineering(the use of living materials in engineering) combined with Bioengineering(The engineering of living materials, I fuess they forgot to google the term before deciding to use it) and we should be able to make a seastead that does the a segnifagant part of the maintenance itself.

    head to http://www.landscapeonline.com/research/article/456 for a brief talk about te use of living matrials.

    Genetic enginerring will most likely be beyond the first few generations of seasteads. as it ether takes lots of money(to directly manipulate DNA) or time(classic selecting breeding). But grafting(en.wikipedia.org/wiki/Grafting) has been used in houndreds of years to create graft-chimras.

    I still working on finding a plant to use to make the floats out of. but we could use a biorock to help reinforce the outside. maybe add an iron oxide to concrete to encrease it’s conductivity? It is already used as a coloring agent forconcrete thou I’m not sure if it’s conductivity or how compatible biorock is with concrete.

    insert FarScape referrances here :P

    It should be possible to build artificial islands using natural species of plants, start with a reed raft on which to grow the various plants that will become an island. it will take years but should not require GM.

    And what, do tell, are the “the various plants that will become an island”? the reed raft will only last a few years. look up theUros, floating islands of reed named after the Indians who inhabite.

    I beieve the referrence is to using them as a platform, much like the floating island with all the Mangos and soda bottle floats… With good selection of plants that tend to float and bind the mats together, you could avoid using plastic bottles, if you started with floating reed mats…

    If you can’t swim with the big fish, stick to the reef

    I get ‘reef raft’ + ‘mystery plants’ = ‘floating island’

    but does anyone know of a good resouce to find plants that can tolerate full strangth seawater?

    Halophytes, Haloavoidant and Halotolerant plants make up about 2% of the plants of the world. Some plants can be bred or engineered for it, through gene transfer… Look for plants in those categories…

    Start with ones that live in those environments that make it necessary to deal with salt water…

    In Burma, they use the FLOATING stems of mangrove palms to provide support for children learning to swim. also the leaves are used to create buoyancy (not sure what for though)

    http://hubpages.com/hub/Edible-Tropical-Plant-Foods

    With a little bit of GM, the mangroves could be persuaded to live in high-salinity water. Bear in mind, they already live in saline waters (though I’m not sure at what salinity) and some mangroves can apparently live in waters up to twice the salinity of seawater (wikipedia). If the resistance of some of the hardier mangroves could be merged with the buoyancy of the mangrove palm, a platform could be created using them as the base, or at least a part of it.

    Wave energy is typically low in areas where mangroves grow,[8] so their effect on erosion can only be measured over long periods.[6] Their capacity to limit high-energy wave erosion is limited to events like storm surges and tsunamis.[9] Erosion often occurs on the outer sides of bends in river channels that wind through mangroves, while new stands of mangroves are appearing on the inner sides where sediment is accreting

    So we could grow mangroves within a breakwater or bay of a floating island.

    Also there are seagrasses, surfgrasses, kelp and various other aquatic plants we can grow. Though we’d need to have a solid foundation, such ferrocement modular islands.

    Corral and seashells that grow on the surface of the of the island can be ground down for making cement,

    the addition clay minerals or ashes can make it a hydraulic cement.

    http://en.wikipedia.org/wiki/Pozzolan

    so we could have concrete floating islands,

    and extend them from things gathered on the island.

    some materials can be harnessed from sea water.

    though some things might be more abundant on land.

    ease of transporation associated with floating on the water,

    should make transporting tons of materials relatively easy.

    i have used mangroves to filter saltwater aquariums. They will grow in full sw.

    Cool, I am not sure mangrove palms grow at the same salinity tho… have to check it out.

    A mangrove is any tree that lives in soil saturated in saline water. It is not a single species or even family of trees.

    So what species of saltwater tree was it?
