The Anchor

The anchor does more than simply hold the end of the ribbon down. The location is critical as is how the ribbon is held.

Value Units
Location Eastern Equatorial Pacific
Facility Floating ocean-going platform
Dry mass 27,000 tons
Onboard Power 20 MW
Maximum Velocity 20 kph
Cost 70M dollars

Status:

Overall facility is mature technology that can be purchased immediately. Hold down mechanism requires development.

Additional Work Needed

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

Item Notes Completed and Ongoing Efforts
Ocean going platforms and airstrips An initial study of the anchor station has been completed but we need to know about the adjacent facilities. We need to know what we can do for housing, floating airstrips, additional businesses or other facilities that will be onsite. We need someone to start working on this - design a floating city. It probably doesn't need to be huge but there will be hundreds of primary works and everyone to support them and the clients that will be coming in.. oh yeh, don't forget the half dozen 20 to 100 ton climbers being assembled (inside) and launched that will each stand 40 to 150 feet tall and as wide when ready to launch
Full design of the ribbon attachment mechanism The bottom end of the ribbon must be held securely under constant tension which means being able to reel in and reel out miles of ribbon at pretty good speeds. This attachment will actuall be very similar to a climber drive system - same tensions, same speeds, same requirements for handling the ribbon. The one additional feature is the spool sitting below deck feeding the hold-down mechanism. On top of this the entire unit must be self contained so it can be moved off the anchor facility to a replacement anchor facility every couple years when the platform needs to go in for repairs - imagine a railroad track between to ships. We need someone to start designing the details and running numbers.
