OK see based on the above diagram, the whole rotating crew quarters also rotates 90 degrees to the original (artificial gravity producing) rotation. Thus the Coriolis force on the crew quaters is minimized. Any comments?

I'm afraid this will not work,

What you will end up with in this scenario is 2 gravity gradients, and 2 coriolis forces. (To make matters worse, these forces will vary over the duration of a rotation).

Coriolis force is a fact of life in a rotating environment. Adding an additional rotation like this will just introduce additional coriolis forces in different directions.

The only way to minimise effects of coriolis force is by building LARGE radius. (ie. maximise tangential velocity)

He's right, if we want no noticable coriolis forces, I'd suggest Bishop Rings, Banks Orbitals and Niven Rings.

Oh yeah, I'd seen this thing mentioned on The OA Worldbuilding List, but I was never exactly sure what it was. What is it exacatly, a bunch of cylinder habitats connected to a a couple rings?

This thread at the Celestia Forum will give you some idea:
http: shatters net forum viewtopic php?t=9011&highlight=rungworld

If you're familiar with Celestia then I suggest you install the Rungworld addon from the website mentioned above, and then either cruise around the Rungworld yourself, or use the links at http: www geocities com traitorsclaw projects rungworld locations locations html to see various views of the Rungworld.

If you haven't got Celestia, it can be downloaded here: http: www shatters net celestia

The traitorsclaw website isn't working.

Looking at realistically, how long do you think it would take to build one of these cities in space? In comparison to the ISS and current orbital capabilites and a few missions to Mars, how would a project like stack up based on current technologies and trends?

OK,

RUNGWORLD webpage is available again. Sorry for any inconvenience. (And thanks Mr Johnson for letting me know about this)

NEVER AGAIN will I host a site at YAHOO/GEOCITIES.
If you're interested, this is what happened to my website: http: shatters net forum viewtopic php?t=9665

Anyway, I've vented my spleen enough... here's the new links:

RUNGWORLD download page

RUNGWORLD celURL's (use this page only after you have installed Rungworld in Celestia)

Please let me know of any broken links or download problems by PM or by email: traitorsclaw at yahoo.com

Thanks

Hm, The OA List has been bashing Yahoo recently as well, why am I the only one with no real issues. I pay Yahoo for my website and I've had no trouble, although, I pay for a whole domain name, so that might change things.

Okay, so I downloaded the rungworld and I'll be sure to take a look at it today.

Based on current technologies and trends? About the same time a Martian city is built: never. Or at least, by the time a new world order is formed and English is a dead language known only by historians.

New trends that incorporate space-based resources, or revolutionary advances in orbital transfer, could change everything. If we have the capacity, I see these things as being built well before a substantial infrastructure on Mars. There's a higher demand for an environment that supports shirtsleeve microgravity and direct access to space.

I agree, some people will like Mars for the novelty, but orbital habs provide a number of things far better; Shirtsleeve environment, micro/zero gravity at the hub for various things (industry, sports, honeymoon suites, etc) and direct access to space. Heck, it would be easy to just push off of one hab (in a ship of course) and drift to a nearby one. Not to mention, agriculture in habs could have a controlled environment, and be more efficient than anything that could be done on a planet.
