Abstract
An improved grounding electrode system includes a moisture collector connected to a grounding electrode. The electrode may have a perforated conductive tubular assembly having at least two circular conductive collars. The whole electrode assembly is buried in the earth with the top end exposed and surrounded by an osmotic conductor. The tubular assembly can be filled with a chemical which enhances the soil conductivity. The moisture collector is preferably a mesh screen to condense moisture from the air and pipe it to the inside of the grounding electrode and/or to the surrounding soil. An osmotic conductor may be inside the electrode and/or in the surrounding soil.
