Marty, since you're in Reno, go talk with the PolyPhaser folks in Minden. They have good info on lightning protection in general and Early Streamer Emission (ESE) devices.
In short, a Franklin Rod attempts to divert a strike to a seleced spot (the rod) which is in turn well is bonded to the earth. Lightning is fickle, but usually this works.
An ESE device differs from a Franklin Rod in that the ESE allows a stream of ions to escape and neutralize the potential lightning strike so that the strike doesn't happen. If this is true, why does lightning stike them?
Other than creating confusion by mixing terms, the article is a good one.
