Yes I found this entry amazing myself when reading the Colorado Spring
Notes.                                        Earlier having built a 10 foot
diameter coil outside I thought it was my imagination
that it seemed to work better in the evening. Of course sunlight also
corona discharge which leads one to suspect an optical illusion. However I
it is not the sunlight but condition of the ground that seems better in the

Incidentally on of the last experiments I made with this large coil and
equal length 1500 ft resonator of 20 inch diameter I operated both by
the two primaries in series and noting the arcing between them, and then
the difference by reversing the polarities of one of the primaries. In this
kind of
experiment I was attempting to send an electrical pulse into the earth by
two ground connections at wide distance of separation, to secure this effect
opposing coil polarities should give. It of course does produce a better
between them when the coils are opposite polarity, but what is surprizing is
amount of reduced discharge that occurs between the two coils when they are
of like polarity. Evidently the smaller stronger coil  overides the smaller
identical voltage
produced on the large diameter coil, or perhaps a small phasing difference
might cause this effect.

To make a long story short, I grounded the large diameter secondary to the
gas mains
about 25 ft away and grounded the smaller coil with a copper post into the
ground right
near its location next to the large coil.. When these two coils are
operating in magnetic 
mutual agreement that produces a longer arcing  between their top
it stands to reason each coil is opposite or 180 phased, which also means
that when one secondary grounding is borrowing free electrons from the
earth, the other is returning them.
I wonder if I could get the opinion of some experts here: if I had instead
used a common
ground for both secondaries would this have increased the efficiency of the
as a whole because of the previous noted 180 phasing? I would think that
would decrease the advantage of grounding in the first place.

About 12 hours after these experiments on a calm summer day a loud
was heard. It was the lightening arrestor on the nearest utility pole, which
made our
street the only one without power. The utility man went around the block
for a burned up squirrel but found nothing. The neighbors of course called
the police
claiming that my experiments were responsible, but I explained to them I
hadnt turned 
anything on that day. Those were the end of those experiments.

On 9/7/99 I will post the results of an ongoing experiment with 180 phased
