A spark-gap tool includes a plurality of electrodes, a mandrel, transductive element(s), and a force transmission configuration. Upon relative movement between components a physical distortion of one or more transductive elements occurs, whereby an electrical potential is generated. A method for powering the spark-gap tool is by physically distorting one or more transductive elements by moving components axially and/or rotationally. A method for treating a borehole is by physically distorting one or more transductive elements thereby creating sufficient voltage potential to cause an arc of selected magnitude across a spark-gap in the tool. A downhole power generation arrangement includes a first member and a second member that are movable and a piezoelectric element on one of the first member and the second member and in force transmissive communication with the other of the first member and the second member.
