Length: 100,000km, anchored on the Earth with a large mass floating in the ocean and a large counterweight at the top end, called an Apex Anchor.
Width: One meter
Design: Woven with multiple strands to absorb localized damage and curved to ensure edge-on small size hits do not sever the tether.
External Power: The power must be external as the gravity well is extreme and lifting your own power is a non-starter.
Dr. Edwards’ approach was to use large lasers pointing up to the climber with a “solar panel like” receiver on its nadir position.
Cargo: The first few years will enable 20ton payloads without humans [radiation tolerance an issue for the two week trip] with five concurrent payloads on the tether for the two-week trip to GEO. [Currently, the plan is seven concurrent payloads for one-week travel.]
What could possibly go right?
