Yep! The Schumann resonance thing looks "bad" We could hope the
Californian's only need there air conditioners running in the day time, but
it looks like relying on the 7Hz frequency is not promising at all. Having
the resistance of the vital ionosphere "link" in our system vary wildly
from day to night is a big unforeseen (by me) mess. The "city" load is
going to mess terribly with the Q anyway so resonances my not be of much help.

I got ~~50k ohms in my other post. Still not bad but certainly not as
wonderful as 10 ohms which would have left lots of room to handle other
problems, like "night".

We do want to stay near Tesla's proposed system. As my quote earlier
mentioned, Tesla was not keen on nuclear power ever working :-)) However,
the 80km high tethered balloons thing is going to need terribly serious
help. If such a nuclear thing could shoot the power up there without the
tethers and such, that may be a vital thing... I am not familiar with
these "Teak" shots but sounds super cool (got any URLs)! Since the low
altitude resistance of the atmosphere will just create energy wasting
streamers ( ;-)) Getting up into the "conductive" ionosphere is super
important!! I think "fusion" things are sort of difficult to maintain
24-7-365?? (moving to the Sun is not an option :-)))
I have not thought much about the ionosphere going and "loosing" our energy
like over the poles much. That is not wanted... Looks like the pure
resistance of the ionosphere link is bad enough.
This afternoon I was feeling sort of good about this possibly working.
Now, I am more concerned...
