A very illustrative description of the idea, and of a few of its
problems.

I imagine how Tesla can have reached this idea: It was much his idea,
at least in practical form, of transmitting AC power by generating
and consuming electrical energy at low voltage, but transmitting it
at high voltage with the use of step-up and step-down transformers.

With high voltage in the transmission line, more resistive wires
could be used, because the required current is lower. With high enough
voltage, any wire resistance could be used to transmit any amount of
power with low losses. At a limit, the air itself could be used. 
The fact that the resistivity of the air decreases at high altitude 
could be used advantageously, effectively insulating the energy from 
the ground. Tesla transformers would be a solution for the huge
voltage transformations required, with the whole upper atmosphere
being used as conductor (really a conductor, not as a medium for 
electromagnetic waves). Large coils would operate at low frequency,
minimizing the losses through irradiation. 

With the state of knowledge by 1900, and considering that Tesla
was very imaginative, this could really look eventually feasible,
specially for Tesla, that could be seing a combination of his
previous realizations.
