Abstract

A lightning shield reduces the chance for a direct hit on a person by placing an inverted hemispherical dome over the person's head and shoulders. The dome has a conductive covering, preferably a wire mesh. The dome thwarts ground leaders from completing a circuit to a descending lightning streamer from a cloud. Embodiments include umbrellas, backpack models, balloons, and mini-shelters.
