dragonstar57 Posted January 31, 2011 Share Posted January 31, 2011 (edited) what are the obstacles preventing a city from being built underground? Edited January 31, 2011 by dragonstar57 Link to comment Share on other sites More sharing options...
lemur Posted January 31, 2011 Share Posted January 31, 2011 (edited) ventilation would be my first thought. second thought is drainage if it's below sea level. Edited January 31, 2011 by lemur Link to comment Share on other sites More sharing options...

TonyMcC Posted January 31, 2011 Share Posted January 31, 2011 second thought is drainage if it's below sea level. Drainage would be a problem if it was below the water table (which could be well above sea level). Link to comment Share on other sites More sharing options...

John Cuthber Posted January 31, 2011 Share Posted January 31, 2011 Great, you just proposed making this http://en.wikipedia.org/wiki/Seasonal_affective_disorder into a practically fatal illness. Even the rest of us would get tired of the lack of light. Link to comment Share on other sites More sharing options...
rktpro Posted February 1, 2011 Share Posted February 1, 2011 NO atmosphere below the surface that will make them spend a lot of money for proper ventilation! And also you can't grow fully when you have no sunlight! Link to comment Share on other sites More sharing options...

CaptainPanic Posted February 1, 2011 Share Posted February 1, 2011 I would suggest that an underground city is only useful if the volume of living space is a bottleneck at a certain location (I'm thinking of Manhattan for example where population density is really high). For most places on earth however, the bottleneck is not volume, but it's surface area (or sunlight, which scales with surface area). Only under the assumption that you have unlimited energy (future scenarios with nuclear fusion, or really clean fission) can volume become the limiting factor on earth.
