RE: Solid versus stranded Wire (perf example)
Hi All,
I believe Brent Turner's (8"?) Secondary is wound with stranded wire,
the he uses for demonstrations. He gets good performance.
Brent (harnessed) sits on an insulator pedestal emitting
~5.5' power and air sparks from his fingers, rings, poles, etc.

No - inductance is lossless. We are talking about losses and
therefore resistance. All else being equal, stranded wire is
measureably lossier than solid section, presumably due to skin
effect artifacts. I have measured this in quite short lengths of wire.
Area for area, litz is better than both as it has a greater effective
cross sectional area due to the insulation between strands. I am not
saying that a resonator built with stranded wire will produce inferior
results however - primary losses and output spark losses are
dominant.
