We welcomed Dr. Paddy Neumann from Australia to the show. Note that the program was originally set for August 2 but due to technical difficulties, we did the program on August 3. I archived the program under the original date for data base continuity. Paddy, as he likes to be called, is working advanced electric propulsion in his lab at the University of Sydney in Sydney, Australia. The Neumann Drive can run on a variety of different fuels but his two preferred fuels focused on magnesium and carbon. He discussed how his drive worked, the advantages it has over other forms of electric propulsion, the advantages his fuel choices have, the uses for his drive and the likely customers. We talked time lines for commercial operations, the big challenges ahead and lots more. Read the full summary for this program at www.thespaceshow.com for this program for this date, August 2, 2016.
