   certainly, very resistant and light material may lead to much   
   simplified design , for tanks and engines (a hose that would not breaak   
   whatever the way you plug it..etc..), and maybe (??) pressurized tanks   
   would get rid of the pumps   
      
   in this way , a rocket may be assembled within a few weeks and ready to   
   launch with reduced infrastructure ..   
      
   then the cost of the fuel may become a concern ... which is not today,   
   compared to the overall costs of launches   
      
   building an elevator would anyway requires some conventionnal launches   
   .   
      
      
   we may never get this magic material for the elevator , though it seems   
   now not completely impossible   
      
   I read somewhere that the resistance achieved and tested for carbon   
   nanotube/epoxy composite was half way to the required strentgh .. with   
   hopes to do better   
      
   the price of the material may now be over ¤/$ 1000 per gram ...   
      
   IF someone finds a way to produce nanotubes by the ton , then many   
   things may have to be reconsidered !!   
      
   that may be tomorrow , that may be never ...   
      
   I am very amused by the perspective of building bridges unwinding   
   something that looks like scoth tape ;-)   
      
   more than this, some people seems no to believe (or make others believe   
   they believe) in the space elevator   
      
   example:

   (they even have a date for it : Countdown to Lift: April 12, 2018 ;-)   
      
   or

   (or maybe this one ;-) : http://www.spaceelevator.ca/  when everything   
   else fails ;-)
