-----Original Message----- From: Terry Blanton >> I think putting roads underground is far too expensive, so I doubt that will happen either (except perhaps here and there in large cities).
> As a former employee of Parsons Brinckerhoff, I agree, in the short term. However, there's the "Big Dig". It actually worked out for Boston. One of the fabulous little-known colonial towns in Mexico is Guanajuato - a town with almost all of the auto traffic AND parking moved completely underground. The town itself is a pedestrian paradise. Unlike the "Big Dig" this was a freebie, in a way. IOW the town had the distinction 300 years ago - back when labor was rather inexpensive - of sitting on a large deposit of silver, so they made the best out of the situation and converted the mines into roads. Why would not some form of subsurface robotic tunneling for roads - in the future history of cheap LANR power, be almost as cheap? ... no silver lining? Jones
