	One might argue that Tesla's (final) coil in Colorado
	Springs, to some extent, fits this pattern, albeit
	larger.  Need not follow, specifically, what was done,
	but that model was the most recent point of an
	evolution of some decades...

	Hydrogen is an excellent cooling gas.  Commonly used by
	utilities (or was) in cooling large generators.

	Worked just fine for 5(?) years, predecessors more or less
	for 30 years.  Hindenburg was the first loss of passenger
	life.  (we should probably NOT go down the Hindenburg
	rat hole...  8)>>  PLease Don't Get me Started...  8)>>)

	Back to physics:
	Hydrogen is a dandy coolant, and only burns IF oxygen
	or another oxidizer is present.  When the entire
	gap (or whatever) is pressurized an _filled_:
	no burn.  Small leaks will disperse, or burn.  Large
	leaks indicate a defective assembly.

	I suggest avoiding flames around hydrogen.

	(it can be argued that keeping one burning will cause
	leaks to burn off, rather than accumulate...)
