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)
