	The long partially-evacuated tube was just a form of conductor, with
earth return circuit.  Not wireless at all!

	For his scheme to work the ionosphere (at a height much grater than 15
miles) would have to be a good conductor.  Granted it was (of course, it
isn't) the capacitance from this to ground would be enormous and to
excite it to the voltages he proposed would have required enormous
circulating currents and incredible energy storage.  These things are
readily calculable, as he could have done if he had thought of it, and
it turns out that his resonant circuit would have required a Q of the
order of tens to hundreds of millions just to keep the no-load power
loss within any semblence of reason.  The bandwidth which would go with
that Q is infinitesimal.  I suggest anyone interested in this form of
"wireless" energy transmission go through a few of these computations
for himself.  His wireless transmission technique hasn't been supressed
by evil men for their own selfish purposes - it is suppressed by simple
ohm's law!  His patents are absolutely explicit as to how his scheme was
supposed to work, with no hidden "secrets" about them, and no room for
the apologists to wiggle in.
