Its not lightning that activates the lightning rod. The way a rod works, is that, during a thunder storm, it has a chance to generator power and spawn a lightning bolt above it. Because of this, it only works with legit thunderstorms, not just plain lightning. Charged ages, TF portals, and TC flux are just lightning. Real storms work, NEI storms just starts a legit storm, so it works. Same for iodine, it triggers a legit storm, so it can be used to generator tons of storms and get lots of eu. (Although i thought that iodine just made it rain, not storm...there is a difference between raining and storming.)
