I disagree. "

	Fine; that's your privilige.  In defense of your belief I suggest you
do a simple calculation.  Tesla was going to have his conducting layer
at something like 20 miles height, and expected it to cover the whole
earth.  Calculate the capacitance between that conducting shell and the
conducting earth - the transmission path he proposed, remember.  [To
make the calculation simple just assume an equivalent flat plate
capacitor of the same area.]  Calculate its reactance at any frequency
you can imagine, remember that he was going to charge it to "100 million
volts", and calculate the current that would have to be fed into that
capacitance to maintain that voltage.  After you do that sit and think
for a bit, then report the result of your calculations.  It gets even
more interesting after you get that far, but that's a good starting
point for a critical analysis of the scheme.
