Orbital Rings

Project Atlantis is about creating orbital rings that provide energy storage, low-cost surface to surface transportation and cheap access to space.  The ring appears to be a steel cable that is accelerated to orbital velocity in an evacuated tube.  It is tethered to ground by a carbon fibre cable.

Whilst this is an interesting idea, the cost of building it will be high.  It will need to pass through the airspace of multiple countries and over large stretches of open ocean.  It would also appear to be vulnerable to single point failure.  An aircraft collision with the ring at any point, would bring it down all over the world.

Re: Orbital Rings

For Calliban re new topic.

Best wishes for success with this interesting new topic!

I'm looking forward to discussion as members have time to consider the idea.  It might work particularly well in service at an airless body such as the Moon.

It sounds similar to a proposal by Jim Cline in 2011 or so.

I'll be opening the link you provided later today.

and some outrageous claims

Carbon nanotube (CNT)

At this point, the spaceship releases the CNT cable back to Earth, becoming a counterweight once reaching 96,000 km in altitude. The climber units will transport materials and eventually people, utilising the strength of CNT to withstand the necessary tension and environmental stressors.

A year old topic

In the past ideas like space elevators were considered wacky scifi ideas but with advances in science people are taking them serious again
