While it could cost $10+ billion to build [...] scientists believe that carbon nanotube material could be the answer.
Yeah, that's going to cost a lot more than $10 billion!
There's plenty of fun tech and mega-structures in this book but I don't think it has anything interesting to say about the plausibility of any of it.
