Interview with Dr. Bradley C. Edwards

Posted by ScuttleMonkey on from the no-elevator-like-caffeine dept.

Keith Curtis writes "I recently discovered that Dr. Bradley C. Edwards, noted expert on the Space Elevator pays $4 for coffee at the same Starbucks that I do. I asked him if he would meet up with me and chat and he graciously agreed. I recorded the interview for posterity. In our wide-ranging conversation we talked about NASA politics, getting energy from space, location, space tourism, software, nanotech, and several other topics."

    I just don't see one, the most fundamental, question in all interview. I don't worry about climber construction or powering them (it's after all "just" engineering - even if powering means, that you'll put very very small reactor on the climber and restrict it going only from 1000 Km and higher and for 0-1000 you'll use chemical rockets) - BUT (!) AFAIK the material is problem! I've read somewhere, that the strongest nanotube ever produced is still only 50% of necessary strength - and THAT'S a LONG way to go! (you can't use just 100% necessary strength - you need more for safety - something like 130-150%!)
