Bradley C. Edwards is a physicist who has been involved in the development of the space elevator concept. ==Biography== Dr. Edwards received his Ph.D. in Physics from the University of Wisconsin - Madison in 1990. His thesis work was in astrophysics on the soft, x-ray background. During his graduate work he worked on x-ray micro calorimeters and several sounding rocket and shuttle payloads. After receiving his Ph.D., Dr. Edwards was hired as a staff scientist at Los Alamos National Laboratory where he was co-investigator on the ALEXIS satellite, developed superconducting tunnel junction detectors, a lunar orbiter, a Mars mission, a Europa orbiter and the world's first optical cryocooler. In 1998, Dr. Edwards began working on the space elevator concept. He received funding from the NASA Institute for Advanced Concepts to examine the idea and published two papers in 2000 and 2003. He proposed methods for deploying a space elevator and overcoming perceived obstacles such as orbital debris, anchoring, climber design, and power delivery and examined construction costs and scheduling, laying the groundwork for current discussions.〔(International Academy of Astronautics - Commission III )〕〔(International Space Elevator Consortium - space elevator in depth the history of the space elevator )〕 He also published two books on the subject, ''The Space Elevator: A Revolutionary Earth-to-Space Transportation'' in 2003 and ''Leaving the Planet by Space Elevator'' in 2006 which gained coverage on major news media.〔(CNN - Express lift to the stars )〕〔(The guardian- The cheap way to the stars - by escalator )〕〔(NBCnews - big bucks go space elevator study )〕〔(NYtimes - Not science fiction: An elevator to space )〕 In interviews Edwards has estimated that price per pound of launching into low-earth orbit could be reduced to 100th the cost of Shuttle missions.〔(【引用サイトリンク】title=Space.com Interview:Elevator Man: Bradley Edwards Reaches for the Heights )〕 Edwards spent eleven years working at the Los Alamos National Laboratory in New Mexico, researching advanced space technologies. He attempted a number of ventures associated with the space elevator concept before apparently leaving the field, spending six years as a senior engineer at Sea-Bird Electronics, an oceanographic company. He has recently started a new company to develop carbon nanotube technology.〔(【引用サイトリンク】accessdate=19 August 2014 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bradley C.
