What I want to know is, was his Wardencliff coil capable of producing
frequencies in the ELF region (Extremely Low Frequencies = 30Hz - 300Hz)???
The first Schumann 'frequency' is 8Hz, but certainly at this frequency the
absorption of the earth would be major problem. The losses would be much
bigger then 1/r^2!!! Sorry guys.
BTW, if you want to know more about 'earth resonance' look at:

This is really a must see!!!
