	In one of Tesla's notes (Experiments --- ?) he mentions that by varying
the tuning frequency of two such coils he could get a variety of
discharge effects.  I don't remember the exact reference but it is of
interest because if you have two signals of slightly different frequency
their added voltages will, at times, be twice the voltage of either at
at other times zero.  No miracles, but would be interesting to see if
you could duplicate his results.
