I don't believe Marshall Savage called it a "Ringworld" however, his sort of habitats did not rotate by the way, he was looking for a way to adapt humans to living in zero gravity, using electroshock therapy to stimulate the muscles. I see the term "Ringworld" and only one image comes to mind.Yatima wrote:Let me have one last go at contributing to this thread in the spirit of imaginative interpretation of UPPs and Descriptions.
A ring of habitats can be something quite distinct from an Asteroid belt, if you want it to be. In his book The Millennial Project: Colonizing the Galaxy in Eight Easy Steps (https://en.wikipedia.org/wiki/The_Mille ... Easy_Steps) Marshall Savage spits that the first step in harnessing more of the power of the energy output of a star (the very purpose of a Dyson sphere and its derivative, the Niven Ring World) is to create thousands, then millions of individual habitats (using asteroids, artificial habitats etc). In this model, the Dyson sphere is not so much a solid shell around the star, but rather a Dyson cloud of artificial and individual habitats.
I find this a fascinating concept, and one you could see emerging much more naturally than the monolithic engineering project that a Ringworld or Dyson sphere requires.
So you could choose to interpret this description and UPP in this way, and therefore make it a lot more interesting than a mere Asteroid Belt.
Ringworld has its smaller cousins, there is the Banks Orbital and the Halo, but if your going to have one ringworld, I would choose the big one. Northstar is the perfect sun for one, it is a class G2 V Solo star just like out Sun, and it only has 4 asteroid belts with no planets to disturb the ringworld. An O'Neill colony is sort of ho hum, the population of Northstar is only in the hundreds of millions. The entry mentions the presence of a ringworld as if that was a minor thing. I would think if there was a ringworld there it would be sort of a big deal! Obviously we need an explanation to square this circle.
