Technical Examples

An underground prospecting method and apparatus that utilizes the harmonics and fractional harmonic waves induced into the earth by the electric power grid. The data are converted to amplitude-depth and phase-depth data. The resulting data may be plotted and are compared to known patterns of the interested underground features, such as hydrocarbon, water, minerals and cavities, to identify whether the features exist and at what depth such underground features lie.
