   As others have stated, more information is needed - i.e. amount of power,   
   cost of NG supply, etc., etc.   
      
   One option for long term durability in a much lower tech form would be an   
   oilfield cathodic genset.  These are large bore, single cylinder, low RPM NG   
   engines combined with a matched genset that are designed and built for long   
   term, low maintainence operation.  Typically used to power the cathode   
   protection on NG and oil transport lines in remote locations.  The engines   
   themselves are used to operate pumps on wellheads in remote locations,   
   running on NG supplied directly from the well. Technology has been around   
   since the mid-20's...
