NASA is starting to take the Space Elevator concept seriously! They're offering $400K prizes for power-beaming and high-tensile-strength tether, essential components of the technology.
A Space Elevator could be one of those epochal achievements like the pyramids, the Great Wall, or the Moon landing -- only more practical, if the economics are anything close to what its proponents claim. Hopefully it won't turn out to be another tech like nuclear fusion power whose viability seems to recede with the horizon.
