In elementary school in the late 1940s, we learned how lightning rods worked and how essential they were to protect houses from lightning fires. And sure enough, back then every house had a lightning rod sticking up from the roof. These days, however, I can't remember the last time I saw such a device. We've never had one on the two houses we've owned over the past 20 years.
Whatever happened to lightning rods, and are they necessary to divert lightning strikes away from buildings and into the ground?
