vaguely recall a number more like 1000uF, but I don't see it in books in
my collection.
Lets try calculating:
Area / Platespacing * 8.9e-12 = farads
4 * PI * 6,400,000^2 / 100,000 * 8.9e-12 = 46,000 uF
To get 250,000uF the insulating part of the atmosphere would have to be
only 12 miles thick.
This is exactly the altitude Tesla referred to in his patent.
Remember, Tesla was trying to utilize a tropospheric phenomenon, NOT
the 50+ mi high region that decades later was discovered to be the ionosphere.
