Design Considerations for the Multi-stage Space Elevator –
To build a space elevator, the toughest challenge is to find material that is strong enough for a self-supporting tether. Building it in multiple stages is a way of overcoming that challenge. Using the concept of dynamically supported structures, it is possible to build upwards from the earth’s surface and provide supports for the lowest parts of the tether, where gravity is strongest. A five-stage design would support a tether made of carbon fiber yarn that is commercially available today. A two-stage design can support a tether with less than one-third of the strength previously thought necessary.
The study report analyses the proposal in detail, covering the underlying physics and technology, design options and prototyping work.

Design Considerations for a Software Space Elevator Simulator –
This study report gives a detailed analysis of all the design considerations for a Software Space Elevator Simulator.
From the Executive Summary:
As with all large, modern engineering projects, detailed computer simulations of the space elevator will be essential during its design, construction and operational phases.
Within the context of these phases, this study enumerated 14 use cases which the simulation software must address, ranging from 3D dynamics and electrodynamics calculations of space elevator motion, to the effects of payload capture and release at various points along the tether, to the effects of friction arising from the interaction of the space elevator climber with the tether. Proceeding from these use cases, requirements were imposed on the software design and an outline for its development was sketched.
