Seems to me that lightning protection for timenuts who put things on masts keeps this from being completely off topic.
People who store explosives in earthen bunkers have learned from many years of experience how far away bunkers have to be spaced so than an explosion in one bunker won't affect others. That same body of experience came up with the cone of protection. It is not a myth. Note that lightningsafety.com sells lightning protection. The scrolling set of pictures on the home page shows a picture of four masts protecting a rocket launch site. Bill Hawkins P.S. Lightning can enter a home in other ways. A neighbor had a direct hit to a tree 15 feet from the house. After generating enough steam in a 2 foot diameter tree to split the length of it, a side strike hit an outdoor light and did considerable damage in the house. The tree was not the highest thing around. That same strike produced an EMP that took out one of my two GPS antennas, about 100 feet away. The time from flash to BANG was about 100 milliseconds. No, I didn't measure it - I experienced it. -----Original Message----- From: time-nuts [mailto:time-nuts-boun...@lists.febo.com] On Behalf Of Van Horn, David Sent: Tuesday, June 19, 2018 11:22 AM About that "cone of protection" http://lightningsafety.com/nlsi_pls/cone-of-protection-myth.html _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to https://lists.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
