Title: Method for locating and evaluating geothermal sources of energy by sensing electrostatic voltage gradients

Abstract: A method and apparatus for locating and evaluating geothermal sources of energy wherein it is known that the earth has electrical currents and that these currents are reflected in electrostatic voltage gradients above the earth with magnitudes in proportion to the magnitudes of adjacent subterranean geothermal sources, characterized by detecting the voltage gradients; individually recording the voltage gradients; and evaluating the recorded gradients for determination of the location and potential of adjacent sources of geothermal energy.
