The core of the Space Elevator is the physical connection between Earth and space. In our baseline design this connection is in the form of a ribbon though earlier designs discussed a round cable.
The primary technical challenge to building the Space elevator has always been the availability of material with sufficient strength. The availability and strength of this material drives all aspects of the space elevator.
