What is the Vret path on this sky battery?  Somehow the circuit must
be closed.  I assume the Vret goes to earth; but, is the circuit
completed by evaporation with a charge on each water molecule?  This
would must impact world weather somehow!

It's mostly from thunderstorms: lightning and neg-charged rain. 
Conventional theory of the Earth Global Circuit has thunderstorms as 
electrostatic generators which on average deliver neg. charge downwards 
and pos. charge upwards. Everywhere else on Earth the slight air 
conductivity lets charges leak back down. I remember one calc that showed 
the RC time constant being about a second, so local e-field should reflect 
what worldwide thunderstorms are doing.  E-field measurements with a 
field-mill normally show a 24hr cycle from 100V/M to 300V/M.  I've heard 
that the peak occurs when African coastal thunderstorms turn on during the 
local afternoon.

Here at the UW we have a realtime tracking program for worldwide lightning 
pulses at 100KHz, with lots of remote antennas.  2D distribution comes 
from sort of a cat scan type of algorithm.

Aha, they're now talking about a remote volcano detector: using the 
lightning network to immediately sense ash cloud eruptions.

I recall old papers about rainstorms: the colliding cloud droplets 
normally bounce and do not meld together, but provide a weak e-field and 
it overcomes the surface-energy issues, and forces droplet-melding. The 
same can be seen in simple desktop experiments: clean water splashed on a 
clean wet surface will roll as distinct beads of water, and not meld. But 
hold a charged balloon a few feet away, and the rolling water balls all 
meld into the wet surface and vanish.


So, new way to destroy civilization: short out the vertical e-field, which 
keeps cloud droplets from becoming raindrops, shutting down global rain as 
well as the thunderstorms creating the worldwide e-field?  :)  But volcano 
ash clouds would probably re-start things again.  That, and winter 
thunder snow storms.  Whew.

How 'bout this one, no wind needed!   :)
