   There is one possible advantage to using high-strength flywheels vs   
   batteries: durability.  Batteries have a limited number of charge/discharge   
   cycles, and replacing them on the moon would be expensive.   
   Magnetically-suspended flywheels wouldn't have much wear at all.   
      
   BTW, I'm missing a large percentage of the postings in this group.  Are   
   others having that problem, or is it just my ISP?
