Tesla's two principals on energy generation and distribution

According to Nikola Tesla, in one of his last work and visions, energy was to be harnessed according to two principles, one of which he was using to implement wireless energy:

Cited Two Principles

He [Tesla] at that time announced two principles which could be used in this [wireless energy] project. In one the ionizing of the upper air would make it as good a conductor of electricity as a metal.

In the other the power would be transmitted by creating 'standing waves' in the earth by charging the earth with a giant electrical oscillator that would make the earth vibrate electrically in the same way a bell vibrates mechanically when it is struck with a hammer.

'I do not use the plan involving the conductivity of the upper strata of the air,' he said, 'but I use the conductivity of the earth itself, and in this I need no wires to send electrical energy to any part of the globe.'
