Pressure in a tube is not the same as air pressure at a great altitude, the
voltage and amperage is already there, Tesla didnt need to provide great
mega wattages.

Theres a very nice patent which was issued in brazil, cant remember much
about it, but the basis was running a wire a mile long supported a fair way
up from the ground which gave a nice few free bucks of wattage, if its true
or not I have no idea, though it didnt make the headlines for a while.
harnessing the wattages from the capacitance of the earth is not uncommon,
Tesla simply took this one stage further.

...... and you would think it could be solved in practice rather than
speculation by now ;-)
