Interesting things you can do with water....
I remember once reading out of a book my first grade
teacher gave me- she saw I was interested in science
fiction novels, and so she gave me this book on the
future, confiding that she hadn't actually expected
there to be anyone who would be interested in it...
that you could simply place an iron cage into most
places in the ocean and it would magnetize bits of
organic debris that contained magnetic minerals and
cement them on the outside of the cage, forming a
thick cement-like layer.... if your robots are fairly
big, you could make a nice hull of some kind with
this, I suppose.... maybe you could even make it a
flat metal surface with no perforations and sort of
scrape templates off of the outside... that way, you
could reuse the same frame a lot of times... all
you'd need to do is put in some of the other parts...
let's see... I think you could build wires by some
sort of magnetization process also, if you can
chemically sift the influx somehow... possibly you
could have a sort of rotor device cutting everything
up, with no outlet except the walls, which would be
magnetized grids... so everything but the conductive
metals would stay. I'm sure somebody out there has a
better method, I'm not familiar with oceanic refining
processes, since I had heard that most of it was in so
loose a concentration that this wouldn't work, though
it occurs to me that if you can accrete a solid layer
of fairly durable cement-like structure then maybe it
wouldn't be incredibly difficult to filter... glass is
easy... sand. It's all just a matter of equipment...
most of which we seem to want to grow. Which may
What if we built the whole thing underwater, or
simply created the island out of "sea-ment" and buoyed
it upwards, anchoring the whole thing with chains...
there's a lot of fun ideas when it comes to ocean
