I agree that Tesla's world electrical system does not appear to be feasible.
However, it does appear the ionosphere can be used as an emergency
electrical system for space operations. NASA has already generated
electricity using a tether from the shuttle. This is something closer to
Tesla coils because high voltages and surrounding electrical fields are
involved.

	Tesla spells out his system very completely in his patents, and stated
that he was going to ionize the upper atmosphere to form a "conducting
layer" which was to serve as one terminal of a transmission line, with
the earth being the return line.  He says it all in language which is
far too clear to misinterpret.  He proposed using a voltage of the order
of 100 Megavolts to do so.  If you calculate the capacitance of the
capacitor which is formed by this layer [assume a more realistic height
of 50 miles, which makes the capacitance less than for his proposed
height] and the earth you'll find that it is enormous, with a very small
reactance even at his lowest proposed operating frequency of 925 Hz.
I've posted the analysis here but forget where I put it.  He stated that
he could transmit enormous amounts of energy all over the earth, with a
loss of "only a few horsepower".  Go through the following calculation:

1. Calculate the capacitance between the conducting layer and ground.

2. Calculate the reactance at any frequency you chose.

3. Calculate the reactive power required to excite that capacitance.

4. Calculate the required Q so that that power would only result in a
loss of a "few horsepower".

5. Calculate the total loss resistance [transmitting coil, vertical
conductor, conducting layer between two points, ground circuit
resistance] needed to produce that Q.

6. Calculate the effective bandwidth of the resulting resonant circuit.

7. Think about it all, then increase the permissible losses by a factor
of 1000 and think about it again.
