Default Standing-Wave Current vs Traveling-Wave Current

Hi Dave,

I am well practiced mixing it up with the masters of obscurity, and I
certainly don't confuse you with Prior Art, or Cecileo. However, the
HVDC project you allude to is new to me (even if it is/was decades
old).

As an aside, I have worked with the lawyer who was instrumental in
closing down WPPS (a nuclear power consortium we generally called
WHOOPS). That consortium agonized that Washington's credit rating
would go down the toilet if we defaulted - barely a blip in the
interest rate resulted when we mothballed several nuclear reactors.

Even further aside, I lived in Japan in the early 50s when they used
DC residential power (and we had to be careful to buy AC/DC
appliances). Woe to those living at the end of the block where the
street lights were dim.

Edison used to portray AC as being the killer current (eventually
selected for use on death row). Actually there were a mix of
characteristics that lent either the death potentiality. DC will
cause the muscles to clamp, and if you seized a hazardous wire, you
could never let go. AC, on the other hand (no pun), would cause
fibrillation, and you stood some chance of releasing the same
hazardous wire. AC, on the third hand (again, no pun), would also
cause the sweat glands to excrete (due to the same fibrillation) and
lower your path resistance (more lethal current).
