A lightning conductor is a metal rod or strap connecting the highest point on a building to the earth. Its purpose is to protect the building from a damaging discharge of electricity between the atmosphere and the building, that is, a lightning strike.

Lightning rods are very simple by design, the original was invented
back in 1750 by Benjamin Franklin.
First we place a lightning conductor (rod + chain) on the top of a wooden house.
We place ether in the house. Ether evaporates and is inflammable. We create
lightning between a generator and the lightning conductor. The house is
sheltered. When we take the chain away, the house burns.
During electrical storms, huge amounts of electric charge are
separated in clouds. Charges near the bottom of clouds induce
equally large charges in the ea
