First, The diode array cools off when operating. Part of
thermal energy is Johnson noise, diodes should rectify
Johnson noise and export it as net DC. The reduced Johnson
noise leads to reduced thermal energy which means cooling
equal to the export of DC electricity. Conservation of
Energy holds.
Second, I do not expect LEDs as the spherical diodes in
the compound photocell. I am treating then as small diodes
that will have a high resistance near zero volts so the
Johnson noise can act to move the resistance up or down
depending on polarity and be sorted into a net forward
flow that can be aggregated.
I did suggest as a separate device that resistors on LEDs
would produce a high enough Johnson noise voltage to
create light. The idea should be tried.
My main interest is using an array of diodes to extract
energy from zero grade ambient heat. This would be
absorbing heat and rleasing DC electrical power.
For a diode, a load resistor, and a capacitor in a loop,
if the saturation current, Is, of the diode is very low
the Johnson noise power will have higher voltage, If the
voltage is higher, the diode output will be asymmetrical
so the capacitor will charge and the load resistor will
dissipate net rectified Johnson noise. The capacitor
shorts out counter Johnson noise, which would be low harm
AC anyway, from the load resistor. The Johnson noise in
the diode only sees the junction capacitance.
The Japanese photocell array is a ready made diode array
when used in the dark, though not optimized, so it may
replace the tedious assembly of SMS7621 small discrete
diodes.
