Did Pons and Fleishman turn their hands to designing Lightning protection systems to redeem their credentials? Interested in your comments *after* you have read the study. http://lightning-protection-institut...-terminals.pdf Yes, let's have more technical discussion and less name-calling, please. There seem to be three observations that need to be understood. 1. The electric field gradient near a sharp point is greater than the field gradient near a blunt point. This is basic physics and should be completely beyond dispute. But that is the field gradient IMMEDIATELY LOCAL to the point... and that's not what lightning protection is about. I would think that lightning protection should begin with the safe equalization of charges. If one could prevent localization of charge, there wouldn't be anything to discharge. Failing that, if one could provide a controlled discharge mechanism, that drains charge without a massive discharge channel, that would also be good. Failing that, you fall back to a point g defense; first dissuading the creation of a conductive channel to the protected area, or, failing at that, providing a specific, perhaps sacrificial path for the massive discharge. The first methods, involving charge management, might be effected by controlling the conductivity of the air. Chemical and mechanical methods seem difficult to deploy and might not be able to affect sufficient volume. I wonder if conductive air volumes, or specific channels, might be created by RF stimulation? Might it be possible to map the atmospheric charge, and through an array of steerable microwave exciters, create specific conductive paths for the relatively safe dissipation of localized charge? I wonder if the HAARP has investigated lightning control possibilities? Ed wb6wsn |
