If I'm not mistaken, Tesla's plan was to set the earth-air-ionosphere cavity into resonance with a wave of about 10 Hz. You would draw power from this wave using an antenna. Some of Tesla's speculations became interesting during Project Sanguine and Project Seafarer, which were programs to develop an ELF transmitter for communication to submarines. (ELF is the band from 2000 Hz down to DC.)
