Rare Jerome Pearson Video Speaking on the Space Elevator Concept

While Sir Arthur C. Clarke popularized the concept of the Space Elevator, it was Jerome Pearson and Yuri Artsutanov who did the original engineering, separately, on the concept originally put forward by Konstantin Tsiolkovsky.
From the video introduction: This was the Keynote address delivered at the 2013 ISEC Space Elevator Conference (held at the Museum of Flight in Seattle, Washington). Mr. Jerome Pearson was the Speaker and talked about his history with the noted Science Fiction author, Sir Arthur C. Clarke. He and Sir Arthur had a long history together and, among other things, Mr. Pearson provided technical expertise for Sir Arthur when he was writing his science fiction classic, The Fountains of Paradise.
