ABSTRACT:
A lightning rod is enshrouded by a large number of electrically isolated metallic points. When a storm cloud passes overhead, a charge is induced in the lightning rod, causing the metallic points positioned near the lightning rod to emit sparks, causing the air about the points to become ionized. These produced ions are accelerated by an electric field produced by two metallic plates, one being electrically connected to the induced charge in the lightning rod and the other being electrically isolated from the charge induced in the lightning rod. The acceleration of the produced ions is strong enough to produce more ions through an avalanching effect created when ions collide with other air molecules in the presence of the strong electric field. This large multiplicity of ions is transported by the electric field set up by the accelerator and guided by a collimator into the atmosphere surrounding the lightning rod apparatus to attract a lightning strike, thus protecting a larger area from the damaging effects of lightning strikes.
