We welcomed Dr. James (Jim) Benford to the program to discuss his book (he was the co-editor) "Starship Century," and his chapter, Sailships, plus his editing of the book. During our first segment of this 1 hour 26 minute discussion, Dr. Benford introduced us to Microwave Power Beaming, sailships, solar sails, terrestrial beamed power, in-space beamed power and more. We talked about microwave beaming as a possible space weapon, the storage of beamed energy, and the use of the millimeter band width for beamed power. Also in our first segment, we talked about possible time lines for development for interstellar travel. In this discussion, our guest used Alpha Centauri B as a reference point. Propulsion in general was discussed with a thumbs down for chemical rockets for doing anything like what we were talking about in this segment. Listeners asked questions as to why interstellar travel was important at this time given it is so far into the future. In our second segment, we talked about his goals in editing the book and the fact that if it is bought through the book's website, www.starshipcentury.com, the proceeds are donated to legitimate interstellar organizations and research. Jim listed several of the organizations being considered for receiving such proceeds and interestingly, most if not all have been guests on The Space Show over the years. Dr. Benford mentioned conferences and the Arthur C. Clarke Center at UCSD. We then talked about the Fermi Paradox and factor L as to the probabilities of finding intelligent life someplace other than Earth. Faster Than Light Travel was a discussion topic, Jim was asked what his non-space friends thought of his microwave beam power work and interstellar travel. A listener asked about students in these subject, particularly in the UK and the US. If you have comments or questions, post them on The Space Show blog.
