Umm... I have two different views on this project.
1- If they ever manage to do actually build it, I see at couple of issues that I find concerning: At +60,000 miles, in the void of space, what would happen if air locks failed? Air from the ground would be sucked right out into space.... Maybe I am a bit fatalist, but it is food for thought.
2- Instead of wasting millions/billions on stuff like that, they should invest all that "play money" in scientific research for alternative energy sources. Anything based on petroleum based is bound to run dry one day. Then what? We all go back to horse and buggies?? Batteries are still too inefficient, in my mind, and electricity, for recharges, is not cheap.
A lot of people have grand ideas of developing/producing Star Trek technologies, but we are a long way from having anti matter engines or anti gravity propulsion systems.
Anyhoo, just my take on this.
