Abstract
A heating device for heating underground soil including a conductor housed in a conductive casing, where when at least one driving current is supplied to the conductor, the conductor generates at least one magnetic field that induces at least one induced current in the casing. The driving currents are of a frequency sufficient to cause the induced currents to generate resistance in the casing, thereby increasing the temperature of the casing. A plurality of the heating devices may be arranged in an array to facilitate the heating of a zone of soil.
