My standing question for that is wouldn't a launch loop have to be located over the ocean, at least say 10 miles out? And then wouldn't it take much longer 25 minutes to take a boat trip out, take the trip and then take a boat trip back in at your destination?

Edit: On second thought if you're spending launch loop kind of money maybe building a 10 mile bridge out to the station isn't that big of a cost?



From what he's said publicly, I don't see how it can be a launch loop or anything much like it.


From the last discussion [1] I thought launch loop was our best guess?

How does a launch loop conflict with anything he's said publicly?

He's said that any loss of power or stability would result in a safe failure mode. I can't see how that fits in with a thousand kilometre long looping supersonic cable in the sky.
