Ascending the ribbon efficiently and reliably is crucial. The climber utilizes current technology throughout and is under development through the Spaceward Foundation Space Elevator Games.
The working climber design is File:Climber.aoi. Notes on the design are located [climberdesignnotes.odt here]
In the grand Space Elevator scheme of things, climbers can be easily identified - they are the things that move. The climber moves up (and possibly down) the stationary Space Elevator ribbon, carrying payload with it.
A picture of the climber is shown below:
Climbers have 3 main parts:
- A beam convertion system, which captures incoming light and converts it into electricity
- A traction and drive system, which uses the ribbon to propel the climber
- A hull, which encoumpases all of the non-climber related functionality, such as attitude control, communications, and life support. **NEAD A TERM FOR THIS**
Most recent work on climbers has been done in the framework of the Space Elevator games.
These climbers demonstrate the principle of a Space Elevator, since they contain all the basic functionality, but do not really have a direct lineage to real spaceworthy climbers.

The climber has the most engineering work that needs to be done and the most opportunity for individuals and groups to get directly involved.
