-------------------------
  I was hoping that it would be possible to get some idea of the input
energy in a certain spark length by this test. For example if the spark
increased one foot and it was found that the input energy increased 2 watt
seconds we could say the energy in the spark is apparently 2 watt seconds
per foot of spark.
  This could help verify some of the other methods we are using to find the
watt seconds per foot of spark.
