text: AJ, you are dodging the question. YOU said we would have "less than two windless nights per year." I said, let's make it just one windless night per year. Hell, let's make it one windless night every FIVE years!
  
  So what happens on that night? Do you have a backup Gas turbine system equal in size to the entire installed wind turbine capacity that will operate on this one night only?
  
  If not how will the grid stay operational? (I'm sure you understand the implication of national grid collapse.)
