Michel,
Just thinking out loud for a moment....
What you are saying in effect is that- in the diode array proposal-
there is no apparent "heat sink" or lower energy dump for ambient
energy, correct?
Since a delta T is required for an energy transfer, then there can be no
net recovery. OK, but....
Have you ever considered the alternative = that being that the way that
the zero point field (or whatever name one wishes to attach) might
operate when properly engineered (in order to give the appearance of
"free energy")...
... is NOT to provide excess energy per se, which is the common
assumption - but instead to provide an enhanced "sink" for ambient
energy, even if that ambient is in the form of electrons coming from
ground ?
I hope you will now ask, 'how that can be accomplished?' ;-)

Well no, it seems he wants to use the photocell (consisting in many tiny photodiodes in parallel) by
itself, or maybe with a resistor, to see if it can rectify thermal noise in the dark.

Hi Charlie,
It certainly will if you cool it, otherwise it should radiate exactly
as much energy (blackbody radiation) as it receives, or do I
misunderstand the concept of thermal equilibrium?
As an exercise in seeing whether I understand what Charlie's getting at, I'll try to answer your
question, and we'll see if I'm all wet.
The key here is the reason Charlie's using LEDs, not ordinary diodes.
If you look at the current/voltage curve of an ordinary diode, it's essentially linear at 0 volts
(it's an exponential, but close to zero we can ignore all but the linear term). This is what the
model says; checking it with an actual diode is a little tricky since the currents involved are
tiny.
The point is there's no sharp cutoff down there -- at ~ 0 volts a diode conducts about equally
well forward or backwards. The "cutoff" comes at ~ 0.6 volts forward bias (for a silicon P/N
diode) where dV/dI plunges rapidly to something close to zero.
A consequence of this is that if you hook a diode, a noisy resistor, and a capacitor in a loop,
the capacitor isn't going to charge -- the voltage on the diode is going to be very close to zero,
and in that range, the diode just acts like a resistor. In other words, it leaks like a sieve.
No joy there if you want practical free energy.
Charlie's idea is that, if he uses an LED, even though noise on the resistor may be able to sneak
through the diode either way (due to the low voltage), once in a while a noise pulse will be high
enough to kick a few electrons over the forward barrier voltage, and a light pulse will come out.
The light then leaves the circuit, and its energy can't be recaptured by the "leaky" diode.
A photocell nearby will catch the light, and turn it back into electricity. The photocell will be
putting out (noisy) DC, not AC, and can be used to charge a capacitor directly.
So, overall, the idea seems to be to use the LED in order to do an end-run around the fact that
diodes aren't ideal.
I started a series of measurements on diodes at low voltage a long, long time ago, in a lab course
in school (dropped the course, never finished the measurements). I've been meaning to do that
experiment over again a little differently from the way we were doing it then (use JFETs instead
of a VTVM), and also check one other thing: Can an LED "run backwards" and operate as a solar
cell? I don't know but I suspect the answer is "yes", which could throw an additional monkey
wrench into the works when trying to use LEDs to cohere noise.
Aloha, Michel

Vortexians,
Looking at the array of hexagonal concentrators and spherical photo
diodes in: photodiodeshttp://www.technologyreview.com/Energy/19696/?nlid=662 I
see a lot of small diodes in parallel so I will try to get one and
see if it aggregates rectified Johnson noise in the dark.
Aloha, Charlie
