Ringworld (CT type)

Did any groups ever do anything with the CT ringworld? What? How did it work out?

Search the archive. We talked about it years back. And more recently we talked about Traveller ripoffs, including the Halo series which is about a Ringworld of sorts.
 
rancke;471952I suppose that strictly speaking I ought to be outraged by the fact that MgT retconned the old [B said:
Secret of the Ancients[/B], but I must confess that my outrage is somewhat reduced by the fact that the old SotA was essentially a bland and boring railroad trip to a vacation at Grandfather's Place.

I *liked* the retcon job of SotA. (Totally agree about the original, Hans.)

I honestly like the retcon of SotA better than the original in this particular case as well. Overall, MgT did a nice job - and added a lot more background information and history to the Ancients period.

Make that three of us...

I've always been a bit iffy on the OTO take on the Secret/Ancients - the MgT version really came across much better (and "believable") and made it much more of an actual adventure. It is also able to be mined for all sorts of great ideas.

Plus, you can still get the PDF for free.

Too bad it's empty and incomplete.

probably a good thing.

The Traveller atlas says the Imperium has about 11,000 planets. Which would mean the ringworld has room for about 272 entire Imperiums.

Of course a full Dyson sphere is even worse. It has room for about 50,000 entire Imperiums.
 
In order do something with the ringworld, you would need two walls, one mobile, both 100,000km long and 40-50km high.

That would be the work of decades for the 3I and the Zho with nothing else major getting done, no wars. Just to make the materials to make the walls, and to transport the wall sections and install them even with TL 15 grav tech, is incredible.

Then centuries more bringing in water, air, and organic materials (or base materials to make them out of) just to get started. 100,000 km long walls, starting with the walls 2,000km apart, is 1.42 e+14 displacement tons just to get material ten meters deep. This is 2,857,142,857 shiploads if the ships have cargo space for 50,000 tons.

Then they could start moving the wall, while keeping up the shipping volume (actually greatly increasing because they would mine out the nearby systems).

I just don't see how the economies of the 3I and Zho, even if totally devoted to the project, get the job done. Even with several thousand ships just hauling materials, I don't see how they survive long enough to get the first section full. (5k ships, each making 8 trips per year, is 71,500 years).
 
So's the Imperium.

At least, until every system is claimed & detailed by a TMLer... ;)

Not the same kind of incomplete. The canon ringworld isn't functional. Canonically, it's got no atmosphere and no soil. Read the quote upthread, where I quote the A12 entry on it.

It's not a ringworld, but the incompleted frame of a ringworld.

And there is nothing in the A12 entry (at least in what Aramis quoted) that says there are no side walls (or even just sections missing).

And even if there weren't, there are many worlds in the Imperium with little or no atmosphere but a large population.

You could build a lot of large domed habitats with extensive hydroculture gardens for food, etc... which won't require nearly as much in the way of resources as making the whole ringworld a fully functional habitat.
 
you could build a small outpost on the surface on the ringworld without too much trouble, true. if no sidewalls were present, it would make quite a nice shipyard location (you could just push the completed hulls off the edge and they'd be in zero-g. landing would be a case of matching orbital velocity with the ring and then easing over the ring).

but that would not even be a pinprick agianst the total land area of the ringworld.
