I mentioned a roof because it should scale horizontally to a basically 
infinite degree, and as a roof it doesn't have to be particularly tall. 
You'll need sup****ts at frequent intervals, of course, but that's entirely

doable. You may be able to piggyback on buildings and utility poles to 
some extent if you want to make it cheaper, but with enough money, roofing

a city with glass ought to be entirely feasible with current technology.
