Now here is a practical use for some of Tesla's magic! I can think of
several people and organizations who should be "down range" Glenn b.

Reminds me of the days just before I got into amateur radio when we
used Model A sparks coils, a battery, and short piece of wire to
generate random noise throughout the HF spectrum; it tended to take out
the ham station down the street that was getting into everyone's hifi.
Also during the 1950s and 1960s, a number of telephone exchanges were
so targeted to test their survivability in the event of an EMP. Their
electronic components tended to fail within the next six months after
receiving a pulse.
