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)
