1. A device for producing deep holes in the earth by the repeated discharges of a condenser bank of large electric capacity of 400 microfarads or more and high electric voltage of 6,000 volts or more which condenser bank is discharged into water by means of a two element electrode fastened at the end of a pipe which electrode has a center element insulated from the outer cylindrical element which encircles it by means of strong electrically insulating material which same center element is in the form of a steel rod and is electrically connected to a heavy electric cable which cable being highly insulated with a plastic covering is connected to a switch in series with the condenser bank and the electrode, said switch being remotely operated by means of a solenoid completes the circuit between the condenser bank and the electrode the current passing through water in moving from one element of the electrode to the other and returning to the condenser bank thereupon producing a very rapid release of electric energy across the electric resistance of the water which is converted to a plasma liberating a great quantity of heat in a short period of time as to produce an explosive impact breaking the earth or rock, ejecting it downward and outward and away from the electrode in increments as the electrode is lowered into the earth.
