A well grounded Tesla-coil transmitter has to apply about 75,000 watts "to keep the earth vibrating so long as there is no energy taken out at any other place."
Experimental documentation would be interesting...
Of course we're not discussing wireless transmission by radio waves. The subject of this thread has boiled down to the wireless transmission of electrical energy by the "disturbed charge of ground and air method" (CSN, p. 29).
100 years of research has only found 'radio waves'.
