I am really surprised that all of the RF-expertise here on Vo seems to
be fixated on capacitive coupling when the initial photo on that page
shows a battery driven isolated circuit with its own signal, where
capacitive coupling is impossible.
As mentioned, RF from AM has been eliminated now as contributory.
On a more positive note, Lindemann has added two videos relating to
another aspect of "cold electricity" to YouTube.

Lindemann is looking at the "cold" phenomenon from a very different
perspective than Stiffler, and he does not mention that experiment at
all, but there could be some cross-connection in the two.
The common thread between Lindemann and Stiffler is the importance of
matching high impedance to resonance, and the fact that whatever
"excess" one wishes to find cannot be apples-to-apples. I suspect that
getting resonance to a high level - 18 MHz in the case of Stiffler by
only ~50-60 Hz in the case of Lindemann, makes all the difference in
finding some (putative) gain.
Lindemann's circuit is not close to gainful, whereas the Stiffler
circuit is possibly gainful and the second big difference is that
Stiffler uses an "active load". The LEDs are probably acting as either
"detectors" or coherers of some kind of wave energy, and possibly that
gives a huge advantage.
Lindemann is able to pull-off the EVGray/ Bedini "battery recharging"
shtick, and in that situation he shows the greatest possible gain, since
the draw drops to minimal. The lead-acid battery is notable for high
internal resistance - so that fits in to a general theme here.
It seems to me that the commentators here have been too quick to assume
that the effect is conservative. Isn't the purpose of this forum to seek
out anomalies, and this process may involve some trust in experimenters
with very extensive experience in these things to have already
eliminated obvious inputs.
