        Sorry -- misunderstanding. I meant to say they would stay somewhere
near transportation to the farmsats.

        The distances seems quite great, and I'm guessing that there would
be habitation areas within the farmsat, if the farmsat is not rotating in
sync with the cylinder.

        I certainly won't want to commute 30++ km just to look at a bunch of
chickens everyday! =)

        That's a loooong looong way for a piggy to travel..

        Given that the colonist wanted to keep most industries outside of
the cylinder proper, is it logical to assume that things like abattoirs and
food processing plants would also be outside of the cylinder?

        It seems almost magical that they can fit so many industries into 72
farmsats... =) Or maybe the outer hull of the cylinder proper is dotted with
these industries, but it seems a trifle dangerous, what with micro-meteorite
impacts and solar radiation.

        How would a farmsat deal with such threats anyway? The cylinder
proper is shielded by the outer shell, along with (IIRC) the idea that water
might be kept between the hulls of the cylinder. But the farmsats are a bit
small for this treatment, right?

        Right. Sorry about that, it's just that a cylinder-shaped colony
comes straight to mind..

        Is such a cylinder feasible? I mean, why are most of the Side
cylinders of 32km diameter and not larger, especially the Side 3.

        For you, maybe. For us newbies, not. =) We get a basic education in
physics here, but it's not really obvious how some things connect to another.

        So.. if we really want a big colony, would a sphere be the best shape?

        I don't recall him implying that the diameter remaining the same, so
it's possible that it will get bigger too.

        You want me to ask him tomorrow? =)

        Ouch. Heavy stuff, water. Guess I should have thought that through..

        Appropriate for a frontier that is, as yet, endless..
