Sounds very cool to me.
A tube would be built and held in the air using magnetically suspended superconducting cables and high strength structural tethers.
I guess there must be some way to maintain the cables cold enough (so that the superconducting properties are there). Do you know how this would be implemented?
If you look at some of the pictures you will see a thick tube every section, that houses the refrigeration and cooling units.
Thanks for the precision. Ahaha here they are ;)
Now the next question that is puzzling me is on how much energy would it cost? Are the 45 dollars per pound including the electricity costs, the maintenance costs, construction costs, etc.?
In 2010 they stated that amortization, spacecraft, and O&M costs are included in that rate.
Excellent then! What are we waiting for? :)
