The cites that Jim gives are most excellent. I am a research meteorologist at
the National Severe Storms Lab and, while lightning isn't my area, I know the
scientists that study it. They have lots of evidence that the porcupines sound
like a nice idea, but the the electrodynamics of how lightning propagates
renders the porcupines ineffective.
