4 Stars – The most recent of three books, the one to read if you read only one, but does NOT repeat all the maps, photos, and diagrams from first two
This book was published in 2010 and is the most recent of the three books that I bought and read, all quick reads.
It covers underground bases, undersea bases, long range magnetic levitation and pneumatic tunnel high-speed transport, and extraterrestials.
The author offers a conversational presentation, he does not use hyperbole, and does his best to be balanced with what he can show is known.
