maglev roads

if maglev roads were built 

with civilian commercial technologies available today 

then it would probably be segments of technology 

placed near each other under and in the road 

but if room temperature superconducting magnets 

were made from carbon nanotubes 

then the road could be weaved from carbon nanotubes 

which would make it a lot quicker and cheaper to build maglev roads 

but then again 

if room temperature superconducting carbon nanotubes 

were made available to the civilian commercial market 

then that would radically change every industry
