[A spin-off article from this talk has now been published in print in the British Interplanetary Society’s “Spaceflight” magazine, November 2015, p.432-33.]

Here is a summary of what I said at my British Interplanetary Society presentation “Building Selenopolis” on 5 March 2008.

I had an audience of about 25 people, who seemed satisfied by my talk, if not wildly enthusiastic. Of course 90 minutes is a long time to listen to one person’s voice, even though I had some nice pictures to show them.

I gave each person a summary sheet to take away, listing the key points. The following is an expanded version of that summary, which should give you a good idea of what it was all about.
