    Found this through StumbleUpon a couple of minutes ago, sounds like it could come in incredibly handy for reducing the maintenance cost of concrete seastead structures – but what the hell do I know, I’m a 19 year old university student.

    (Is this in the right section?)

    While the bio-brick aparently exists, which was covered in another thread, this is only a desireable idea, until such time as they can get it modified to fill cracks. My suggestion would be to use the same ones as in bio-brick and something like a caulk-gun to apply a grout of the bio-brick stuff.

    Several problems are: How is the bacteria to know it has reached the bottom of the crack…? If it only works in a specific range of Ph and conditions, what does sea-water do to the whole equation?

    I see problems with the whole idea, maybe using the bio-brick and a floating dry-dock would be a better consideration.

    Never be afraid to try something new…

    yes, ideally we would use something that can stay alive all the time.

    the gengineered stuff with the self-destruct genes is vendor lock-in, just like monsanto and their self-destructive crops.

    I do agree with using some kind of live symbiotic organisms that plug the holes and extend the craft,

    such as for instance using coral or some other live-rock types that live in the ocean.

    of course another issue with it is that live-rock only grows in certain regions,

    so it would be best to have an ecosystem of different kinds that grow at different water-temperature ranges

    and can hybernate till conditions are appropriate for it to grow.

    If you could find out the orignial bacteria name that could be helpful.

    Eventually we should make a list of all the live-rock bacteria, for use in our concrete mixes.

    by the way here are 2 related threads
