	Lighting a filament (a demo Tesla used to do) I've
	not tried.  The physics are simple:
		need to get enough current into the filament.
	(Tesla used to use Very heavy copper, i've heard
	tales of bus bars....) to demonstrate that The Freqs
	are Different and the behaviour is different.)
	Random thoughts:
		Pick a LOW CURRENT lamp (measure them)
		Flashlight lamps are high current FOR THE
		EQUIVALENT WATTAGE.
		Try a multiturn coil.
		Fat Wire (current operated device).
		Build a series resonant circuit AT THE COIL
		freq?

	Not enough current.

	(Filaments are very nonlinear.  Might be Just
	Under incandescence and Not Quite There.)
