    Any arc or spark is inhernetly negative resitance over much of
    its range.

    Poulson also used arcs as oscillators, using the negative resistance
     charactereistic.  I'm unfamiliar with his using _spark_ techniques,
     that may be just me....

    (has anyone tackled an _arc_ CW Tesla Coil?  8)>>)
