Bart,

So you think that that massive salt water cap bank is
only around .1 uFd? Maybe it's around .8 to 1 nFd per bottle then. I 
can't quite remember what the ave-
rage capacitance per bottle is, can anyone refresh my
memory on those figures? Note that these appear to be 750 ml wine 
bottles too, not 12 oz Corona beer
bottles - approximate twice the liquid volume capacity
with the wine bottles over the beer bottles. I'll try to
contact him back again and see if I can get more info
from him about his secondary coil, primary coil, and
toroid dimensions. Another thing that I noted was the
long trnsmission lines from the power supply/capaci-
tor bank assembly to the coil in its outdoor firing po-
sition. This looks like another source for loses in ad-
dition to the lossy salt water caps.
He did say that he was using just plain table salt for
the brine solution of his bottle caps after previously
using Epsom salts. The Epsom salts solution woud
freeze in the harsh Maine winter conditions but the table salt brine 
has never frozen on him. He has had
these wine bottle caps with the table salt solution for
four years now.
