Haven't we already established that there's no continuity among the books, that each is an alternate variation on the theme? So nothing would really carry through from one sequel to the next.<br />

Was it the big diamond mountain? I liked how that was the justification for the space elevators (although iirc even diamond actually does not have the compressive strength to serve as a tower-style elevator).

</blockquote>I don't know the specifics discussed in the book you're referring to, but space elevators rely on tensile strength, not compressive. The center of mass is in geosynchronous orbit and the elevator hangs down to the surface from there. So it's necessary to find a material with sufficient tensile strength to support all that weight. These days, we know that carbon nanotubes are probably the answer, but even before nanotubes were discovered, it was expected that some sort of diamondlike carbon-based fiber would be the only thing strong enough. Clarke assumed as much in <i>The Fountains of Paradise</i>, the seminal SF novel about space elevators, and it stands to reason that he would've used the same principles when writing about space elevators in a later work.

And if one looked very carefully, it was just possible to make out the thin thread of the Panama Tower, one of the six umbilical cords of diamond linking Earth and its scattered children, soaring twenty-six thousand kilometres up from the equator to meet the Ring around the World.

'Go closer to the window,' she said, very softly. 'So that you can look straight down. I hope you have a good head for heights.'<br />
<br />
<br />
What a silly thing to say to an astronaut! Poole told himself as he moved forward. If I ever suffered from vertigo, I wouldn't be in this business...<br />
<br />
<br />
The thought had barely passed through his mind when he cried 'My God!' and involuntarily stepped back from the window. Then, bracing himself, he dared to look again.<br />
<br />
<br />
He was looking down on the distant Mediterranean from the face of <b>a cylindrical tower, whose gently curving wall indicated a diameter of several kilometres</b>. But that was nothing compared with its length, for it tapered away down, down, down - until it disappeared into the mist somewhere over Africa. He <br />
assumed that it continued all the way to the surface.

To my understanding, it appears that Clarke used a compressive tower design (and calls 'em towers, and never calls 'em "tethers") in 2061 and 3001. The ring would be effectively weightless but I don't think there's a mention of a counterweight or anything like that.<br />
<br />
It is, however, only explicitly diamond in 2061. But given the significance attributed to the diamond in 2061, I don't think it's too much to assume that the same diamond was used in 3001, albeit reduced from six towers' worth to four.<br />
<br />
Note: this is not at all an argument that such construction <i>would work</i>. It wouldn't, for a number of reasons (compressive strength of diamond or other, even stronger materials is still probably too low; diamond cleaves and an impact would, I believe, smash an elevator quite badly; more speculatively, diamond oxidizes into CO2 or CO or decomposes into graphite in extreme conditions, which the upper atmosphere and open space both qualify as).<br />

2061 was a pretty cool book, really. It had Roy Scheider in it.

There are still some elements that carried through: The second mission to Jupiter, life on Europa, the stellation of Jupiter, HAL joining Bowman. If anything, it's <i>2061 </i>that was ignored-- at this sleepy moment, I can't think of anything that carried through from that one.

The Galaxy's crash on Europa is referenced specifically, and the above-noted space elevators in the epilogue carry through as a concept.<br />
<br />
Without rereading it entirely, I want to imagine that the other two got knocked down and no one wants to tell Poole because most of the time he's in one, or standing next to one, and that's just a ghoulish thing to do. <img src="/styles/flatawesome/xenforo/smilies/shifty.gif" class="smilie" loading="lazy" alt=":shifty:" title="Shifty :shifty:" data-shortname=":shifty:" /></div>
