 I would start with the study of lower frequency
resonators since apparently the great problem is that
resonant circuits in the 8 to 12 hz range are not
easily buildable, so first we can study existing
models and speculate from there what the requirements
would be if the same circuit were to be lowered in
frequency. I have a particular low frequency resonator
that might be used as a model; where it exhibits a
30,000 hz resonance from 25-30pf scopings; but the
coil is only a square succession of 20 zig zag spiral
layers of 30 winds, for a total of 600 winds. The
layering method is responsible for a certain amount of
internal capacity in the multiwound coil where it is
the voltage between layers that becomes predominant in
the internal CV^2 term, and not the voltage between
actual winds that makes little contribution. One
mathematical model based on comparing a diagonal
layering method for a 25 unit array compared to the
conventional zig zag layering showed that the
diagonally wound model would have almost 6 times more
internal capacity, where if this were true the
existing inductor  using diagonal windings resonating
at 30,000 hz would now resonate at 5,000 hz. Now this
particular inductor already resonates 13 times slower
then what quarter wave value estimations give, where
each wind is only 20 inches in circumference.
Supposing then the wire route change were able to
accomplish a 5000 hz resonance, how far would I have
to expand the circumference to match 500 hz from an
alternator? Ten times the initial 20 inch per wind
equals 200/12 = 16.6 ft per wind, or a diameter of
only 5.3 ft. To model a further reduction down to 10
hz, this would be a 50 fold reduction yeiding 830 ft
per wind, for a huge diameter coil of some 264 ft.
Just some idle speculation of what a earth frequency
resonant coil might look like...
