	I fail to see the similarity.  One might call a
	motor similar to a Tesla Coil.

	I suggest key elements of Tesla Coil are AC
	(or rapidly varying/pulsing DC), and resonance.
	Nether is present in this case.

	The concept of running anything 'thru' a Sun seems

	iffy...

	Sparks occur in vacuums.  DIFFERENT sparks, but
	sparks

	To do what?

	If the objective is to generate power, as in the
	previous: that depended on the length of wire at
	right angles to the direction of motion.

	Unwillingness to proceed with it, rather.
	Note that utilities routinely manage miles
	of wire at megavolt and up.  If NASA wished to
	proceed, the know how is out there.  Also: the
	power is NOT free.  Its a drag brake on the
	orbiter...

	The tether generator requires the wire extended...

	So is utility engineering.  Lots of professional
	advice available.

	cf above...

	I think not.  The effect is DC and NEEDS a longer

	wire.  (There might be advantages to a toroid, for
	other reasons.)

	I'd think not.  cf above...
