use the coils (transformers) and form
something like a tree-diagram...
1 coil to 5, 5 to 25, 25 to 125 and so on...
the first coil pass thru the lightning
conducter, the conductor is made of high
resistance wire...
the coil would have flux change, thus
is the 5 coils, the 5 coils change the
flux in the 25, the 25 change the 125...
all lowered voltages could be tapped...

if there is a lightning, e.g 100000000 volts
split into 500000 sub coils, then each would
have 200 volts of electricity...
if a thunderstorm has 10 lightnings, the
conduction could produce 1000000000 volts in
1 or 2 seconds, divide by 1 hour (3600 secs)
there would be 30000 volts, in 3 hours there
would be 10000 volts, the voltage can supply
250 volts for 40 hours, just if there is a
battery to hold the voltages...

in theory, it should work....in theory...
