When reuseable space craft by SpaceX are a reality (likely later this year) there will be no economic need for a space elevator. Its the same reason we will probably never build super high speed rail systems over most of the US. The cost benifit just is not there. When the cost of going to space is reduced to mostly a matter of fule space is very accessable very cheeply. Not much more expensive than a flight in the concord was. The real cost is throwing away the rocket everytime you use it. Build rockets with the reuseability of jet airplanes and presto cost to space is no big deal. No one talks much about building high speed rail across the ocean because an airplan can get you accross very fast for a tiny fraction of the cost of the rail system. Same with space. Build a 30,000 mile elevator to space at $1,000,000,000,000 or a $50,000,000 space ship that burns $300,000 worth of fuel per flight.
