This week we’re joined by one of our favorite regulars, Fred Scharmen. Fred currently teaches architecture and urban design at Morgan State University's School of Architecture and Planning, and is the Principal and Co-Founder of The Working Group on Adaptive Systems. What brings him on today’s show is his just-released new book Space Settlements. The 400-page paperback contains a visually stunning collection of designs for space colonies from the mid-70’s, including iconic artwork and comparison studies of 20th and 21st century architecture projects. Our conversation talks about his research leading up to this book, the process of writing the book and the fascinating stories discovered along the way.
