Dr Bae returned to the program to discuss his new book, "Photonic Laser Propulsion" plus he explained the technology, answered many listener questions plus we talked time lines, a general development plan, the Moon, Mars, beamed laser propulsion comparisons, chemical launch rockets, economics and our vision for humanity's future. Dr. Bae started out with a lengthy intro to the book and his photonic laser propulsion work, he used a quote about inspiration from Carl Sagan and much more. Later in the discussion, when he was asked for his plan to get his ideas and work to policy makers and those that develop tech, he thought that would be take up by maybe other governments, interested parties, private funders. He thought his work was complete as a scientist by developing the tech and putting it out there for all in his book. We talked about funding, specifically gov. vs private funding. Also mentioned was human spaceflight, tourism, and settlement. Don't miss how it tech might apply to each of these categories plus timelines for them.
