   Assuming this is the system that JP Aerospace described at Space Access   
   (that URL isn't working for me at the moment)...   
      
   No outsider has yet been able to make the numbers add up for the system as   
   described.  It seems to assume impossibly good aerodynamics.  With the   
   caveat that right now there is only very sketchy information about the   
   design, the general conclusion so far is that either there is some quite   
   subtle trick involved, or they've goofed.
