RE: [TCML] Safety Issuie

["Gary Lau" <glau1024@xxxxxxxxx>]

I think we all agree not to run a coil without a secondary or equivalent
load.

I've not personally tried it, but I'm guessing the reference to the
"aluminum pan with water" is to load the primary through eddy currents
induced in the aluminum pan.  The water I think is there only to boil off
and keep temperatures sane should the test be done for an extended time.

I don't think that matching impedances exactly is important.  We just need
to have a place for the primary energy to go to.
