John Batchelor and I welcomed back Dr. Haym Benaroya to discuss using 3D printing, robots, drones and reusable rockets for lunar and Mars settlement.  Dr. Benaroya had much to say about 3D printing in space and the pace at which the industry is moving forward.  He explained why the use of robots and drones would take longer given the challenges faced in these industries in working in the space environment.  The subject of advanced propulsion & the lunar space elevator came up.  Not only did Haym say it was probably doable for a lunar elevator given the materials we have today, he was considering a proposal to NASA for a lunar space elevator demo that would be self-deployable.  He briefly explained his amazing concept.  He said for Mars and lunar travel, we would be using chemical rockets for a long time.
