Abstract: A method and device for generating an electric current and power from the earth's electric field. The electric current is generated by providing a thermoemissive material at some distance above the earth's surface, connecting the thermoemissive material to the earth's surface with a conductor (e.g., wire) such that a conductive path is established between the thermoemissive material and the earth's surface through the conductor, and heating the thermoemissive material to cause it to emit electrons into the surrounding air, thereby drawing replacement electrons from the earth's surface through the conductor to the thermoemissive material. One way to produce power in the above setting is by installing a D.C. electric motor or other electrical device along the said conductive pathway.
