[NewCandle] more D2O anode glow comparisons

[Nick Reiter]

Hello, all,

Been away from the experiments for a couple of weeks
attending to some family matters and added work load. 
Here's whats up:

Last week, I took a suggestion from Sam Faile, and
made some more brightness comparisons between 1M
citric in normal DI water and the 1M citric in blended
heavy and light water.  However, this time, I tried to
set up not for similar current, but for similar or
balanced power.  I think I had been assuming the
brightness of the anode glow in my different
configurations was linear with current, however, with
the difference in apparent conductivity of the heavy
blend, Sam felt that I needed to show that similar
total power dissipation would or would not yeild
comparable brightness.

Again, the device of choice was the small beaker with
coiled 316 stainless wire cathode and central 4043
aluminum alloy welding rod .125" diam.  Power was
applied from my HeathKit DC 0-500V supply.

I took some good 5 second digital camera exposures,
which I then put through the auto-enhance, etc.  Even
with the light water run at 27.45W and the blended
heavy run at 25.55W, the heavy blended solution run
was noticeably brighter and whiter.  No Geiger counter
reactions to note.

I am sending along a little later this next comparison
photo set to Keith.  For some reason, I had trouble
with the focus on these, so they are fuzzier.

Sam Faile reports that he received his order of D2O
finally, from United Nuclear.  His first test was to
add a few ml to his long running dual aluminum foil
(center skinny strip, outer parabolic large strip)rig
in 4:1 H2O-prestone antifreeze.  Sam reports that when
he added the approximately 5ml of D2O to the 1 liter
of prestone electrolyte while running with 120VAC,
there was a temporary (maybe 10 minutes or so)
brightening of the glow at about the first inch of
aluminum (both electrodes) below the solution surface.
 Now the odd thing is that Sam stirred the D2O in - it
didn't just puddle and then diffuse naturally.  Why
just the first inch of the Al strips went bright, we
are at a bit of a loss.  As the initial brightening
effect faded, it appeared as though the overall
intensity of the whole electrode arrangement may have
ended up slightly brighter in the end, but difficult
to measure by eye.  However, Sam vouches that it was
an easily seen effect in the first 10 minutes.

He has more experiments planned for this week.

I'm feeling far less sheepish than I was a couple
weeks back about recommending it to others for
replication.  I do believe the D2O makes a difference
in luminous intensity of the blue-green-white regime
of anode glow.
