	With great difficulty....

	That's one way to look at it.  I find it more understandable
	as:
		High Q circuits have low losses.
	Generally this amounts to the same thing.

	I'd not phrase it that way.

	First, decide which 'that' is of interest:
		Primary circuit Q?
		Secondary system Q?
		Overall Q?
	Then:

	That's the obvious way, and the principle one.
	'bigger' wire.

	Primary Q is also influenced by Capacitor losses
	(Dielectric losses) and gap losses (many threads
	on this).

	Corona losses, as they rob energy contribute.
