Yes.  However, remember that as the spark gap fires and F increases, A also 
increases to match it, so the energy in the capacitor remains constant.

I can't see how.  Personally I attribute the high peak powers to a large 
current at a high voltage, although rumour has it aliens, the ghost of 
Nikola Tesla and/or Tim Bearden may be involved...
