Semi-resurrecting my own thread...sorry.
I am still having a huge problem with hive cities.
While I have not read a huge ammount of books, those I have seem to almost universally reject the so called 'environmentally sealed' spires we see in all the artwork.
From the open aired grand parade in the Eisenhorn novels to my current read, Helsreach, all talk of open topped city walls.....huge open highways and open rooftops, and multitudes of civilians...who supposedly have never seen the sun....under exposure to air attack.
I'm not criticizing the books....Helreach in particular is an awesome read, but maybe the authors are having the same trouble as I am visualizing a completely enclosed cityscape.
For instance why does Grimaldus worry about the exposure of his food and water supplies to air attack if it could just be taken 'indoors' and protected by kilometers of outer shell and city structure? This is on Armageddon a world that supposedly you can't breath the air right?
Why also does Helsreach need city walls when, by definition, a hive city is nothing but one huge outer wall stretching to the clouds?
I guess my minds eye isn't up to the task of conjuring up the closed environment, I keep coming up with a mix of blade runner and coruscant instead.
