Finished O'Neill's book

The last chapter was in his words, speculative.  I won't comment upon it much.

Mostly, I was interested in the nuts and bolts of his ideas.  The "how-to" part. Basically, he was depending upon the Shuttle to perform according to its expectations, which it did not.  The rest of his ideas collapse after that.

In short, in order for his ideas to be put into practice, there needs to be at least, a much cheaper access to space than what exists now.

He didn't express much interest in nuclear power, believing that it won't be necessary.  It appears that it will, unless Elon Musk of SpaceX can figure out a way to make his rockets reusable.  In other words, Musk will need to succeed where the Shuttle failed.

Without success there, it may come down to fusion propulsion.  In that case, the high energy output of fusion may make single stage to orbit spacecraft possible.

Also, there is JP Aerospace and his airships.  People may ridicule that idea, but what if it is the only way?

Well, that's all for today.  Thanks for coming by, and have a great evening.
