[NewCandle] Ron Stiffler thread

Thu Feb 7 11:48:02 EST 2008

Hello Dr. Stiffler, and welcome to this nefariously
subdued group!  It is indeed - in my opinion - a haven
for a tad more critical thought than one might find
elsewhere.  I like it here, a lot less talk and a lot
more experimentalism and empirical results.

Thanks very much for explaining your recent work and
results.  I myself have not worked with your concepts
as much as Jones has, or in as diverse a way.  Since
late last fall, I've mainly focused on the basic
Thomas oscillator driving LEDs.  Originally, my
interest was (and has been) more with LED anomalies in
general, and as my earlier post this morning
indicated, I am still looking at that outside of HF
driving concepts.

One of the other reasons I picked up eagerly on the
work of yours and others described by Jones
originally, was that as early as 1994 to 1995, a
retired scientist friend of mine and I had
experimented with power extraction from large
non-inductive antenna arrays feeding diode pairs and
bridges (It wasn't until about 1998 that I even heard
of the AV Plug!)

At any rate, welcome, its a pleasure to have you here.

Keith, to reply to a couple of your points:

************That I had repeatedly checked with
different driving power sources, from HVDC to
rectified 60cy to rectified 30KHz bugzapper to the
current Thomas oscillator arrangement.  Using a
calibrated Si cell.  From what I can tell, there seems
to be no deviation of more exotic power sources from
supply DC, as long as there is filtering capacitance
on the downstream side of the rectifiers or AV plug. 
With a green LED, conversion efficiency of light into
photocurrent by the Si cell is about 20%, and is
lawfully linear with applied current to the LED.

The weird happens in other ways:)

The Holy Grail 'neath ancient Roslin waits.
The blade and chalice guarding o'er Her gates. 
Adorned in the masters' loving art, She lies;
She rests at last beneath the starry skies.
