The Space Elevator

Book excerpt: The authors take the reader through the history of the concept, technical design and economic practicalities of building an elevator to space, and, ultimately, the implications of what such a low cost transportation system would mean to society. Based on three years of NASA-funded studies and written for the technically literate layperson, Edwards and Westling discuss the recent technological advances that now make the space elevator feasible. They conclude by addressing the effects that the space elevator could have on mankind's future from communications and energy to colonizing space.
