Upsides To Making A Portal To Heaven  
   To   Build  The   Factory   There    
  
                                          
 First  Of  All,  Real Estate: The Highly 
 Fractalized  Geometry  (Not  Proven  But 
 Likely To  Be  The Case) Implies  Almost 
 Unlimited Room; Even If The  Portal Tech 
 Would  Be  Stolen,  Chances  Of  Running 
 Into A  Competitor  Is  Close  To  None, 
                                          
 Secondly,  The  Resources:  Heavens  Own 
 Alchemical   Properties  (Proof  Exist!) 
 Makes  Most  Base  Materials  Easily And 
 Readily  Available.  Once  The Molecular 
 Movement  Patterns Are  Mapped  Out, Any 
 Compound   Can   Be  Created   Virtually 
 Without                            Cost. 
                                          
                                          
  
   Downsides  To  Making  A  Portal To  
  Heaven  To Build  The Factory There   
  
                                          
 Current Portal  Tech  Takes  Some Energy 
 To Hold Open, Which Isn'T A  Problem  In 
 Itself.  Test Results However  Has Shown 
 That Without An  Active Tether, Heaven'S 
 Time  Flow Breaks Down Completely.  Even 
 A Momentary  Fluctuation  Of The  Portal 
 Would   Render   All    Remote    Assets 
 Practically  Lost.  Much  Care  Must  Be 
 Taken   To  Maintain  Portal  Stability. 
 (One Option  Could  Be Several  Portals)
