The LiftPort Group has a bold and interesting plan -- to build a massive space elevator before 2020

The LiftPort Group has completed a second round of testing on a prototype space elevator platform that stretches a mile into the sky, which allows a robots to climb and descend the ribbon that is between the two platforms.  The LiftPort Space Elevator would allow a revolutionary way to get cargo and supplies into space -- using a cable thousands of miles long tethered to  an object in geosyncronous orbit.  The company hopes to build the space elevator by the year 2018, but the task will obviously not be easy.  The observation and communication platform that robots climbed is properly dubbed HALE, High Altitude Long Endurance.  HALE was secured in place by several high altitude balloons for over six hours.

The ribbon that will hopefully stretch 62,000 miles from Earth into space will be made of carbon nanotubes weighing less than 1.5 pounds per mile.  Although initial testing was done in Arizona, the space elevator will likely be anchored to an offshore sea platform that will be located somewhere in the Pacific Ocean.

Nothing has a perfectly circular orbit, and what is considered a minor change can possibly affect miles of the tether, therefore creating variable slack and maybe even stress damage. I don't see this happening at all.
