During our first segment, Dr. Laubscher talked about carbon nanotubes, the manufacturing process, how to move the process and technology forward, end uses for the product, possible timelines for advancement and the current day use of Chemical Vapor Deposition (CVD) in the process. Bryan talked about the need to find a better process for making carbon nanotubes than CVD. Later is this segment, Dr. Laubscher was asked about the potential relationship to space other than with the space elevator. This was an interesting discussion , don't miss it. In our second segment, Bryan talked about how hard and challenging the space elevator was and later in the segment, due to a call from Pooley, we went through many of the top challenges faced by the elevator with a status report on each one. As this segment was opening, I did ask Bryan for a time line for space elevator advancement. Our guest suggested that at some point, there would be significant demand for the elevator. Next, we talked about the upcoming International Space Elevator 2014 Conference to be held at the Museum of Flight in Seattle, August 22-24, 2014. For conference info, visit www.spaceelevatorconference.org. John from Ft. Worth called to talk about materials, composites and much more. We also talked about the strength needed for the elevator ribbon and John asked about SSTO. Blaze emailed us about nuclear waste and Bryan had an interesting take on it. This was another valuable discussion, don't miss it. Dr. Laubscher talked about ribbon length, characteristics, strength needed, and its location in space, plus the counter weights it would need. Adrian emailed several questions to us about the ribbon breaking and related issues. He also asked our guest radiation issues. Doug emailed about ways to climb up and down the ribbon. Some of the other issues that came up were wind, lightening, ribbon oscillation, space debris, policy & regulatory issues. As our program was ending, Bryan offered us words of wisdom and said his company website was www.odysseustech.com. In addition, Dr. Peter Swan emailed us about his paper on the elevator which you can download and read at www.virginiaedition.com/media/spaceelevators.pdf. Post your comments/questions on TSS blog.
