In this months US Airways magazine, Kristin Ohlson has written a fine article / overview of the Space Elevator.
She quotes a number of “leading lights” in the field (Dr. Brad Edwards, Ben Shelef, Michael Laine, Ken Davidian, etc.) as well as some “lesser lights” (including yours truly).
It’s a good article – well worth your time to read.
