Tesla never produced any ULF at earth resonant frequencies in Colorado!
	(Lowest frequency he used at power was about 50Khz)
This was a hypothesis he formed after receiving returns from advancing 
and receding thunderstorms.  He hit the nail on the head about the 
frequency, though.

Wrongo!  Tesla was constantly limited and hampered by the technology of 
his day!  He seemed to always be seven leagues ahead of his 
contemporaries and available technology.

Mica caps would have been better for him, but no such units were being 
made at that time to stand the voltage.  Salt water and glass , as poor 
as they were, amounted to the pinnacle, the acme, of technology at his 
level of usage in 1899!  He always used the best of the best!

Believe me, Tesla would be ordering custom built government spec. 
polypropylene film and end foil construction pulse caps were he doing his 
work today!

This is a great idea from a number of insulation standpoints, too!
Speed controlled by a valve, etc.  A turbine Gap!  Add the concept of 
series gap quenchin' and you are there! Good goin'!  The expense of the 
air supply will keep all but the most ardent coilers away, though.  For 
most motors are free to cheap.

Chip,  Earth resonance has to do with electrically exciting the 
transmission line (or 1/4 wave line) which is a line linking the 
antipodes usually, but according to the Corums in July at the ITS 
gathering, it can be any cross sectional line through the earth.  On 
the anitpodal resonance, Tesla was accurate to a fraction of a hertz on 
his original estimate!!

A resonator can be a piece of wire, a coil, a stretch of even high 
resistance conductor (earth)!  A signal injected into it (via the ground 
in the case of Tesla's original concept) will reflect and build at or 
near resonance by standing waves which can be altered by slight changes 
in the frequency.  Nodes can be set up and power taken at any point.  I 
am still on the fence about actual implimentation of the concept, but it 
is intellectually feasible.
