I must've missed a few classes; are you talking about creating or removing heat
in a general sense, starting an atomic nuclear reaction, or simply producing
energy? I joined the group last night and, obviously, missed a few emails, too.

Thank you for posting the Mr. Wizard video. It was an excellent
demonstration.
Here is a simply circuit which performs non-linear mixing of two waves.

The diode is the non-linear circuit element which does the heterodyning.
This circuit is an
The nonlinearity must be attached to the cathode itself because a THz
signal will not go through even 1 micron of electrolyte. In the
Letts-Cravens-Hagelstein experiment, a tiny amount of gold was added to the
cathode to produce the nonlinearity. Did it work because it formed a diode
junction?
Sounds fascinating. May I ask: what are you using as your non-linear
element, to cause the two laser beams to heterodyne? Is it the target they
shine on, itself?

I think in principle it should be possible to generate moire patterns with
fractal characteristics.

Hi Harry, interesting thought...
The film camera isn't a pattern contributor toward Moire interference
patterns, but it does have a random granularity in the photo emulsion.
Could the 'freaky patterns' that are created by overlaying random dots,
linked below, qualify as your "sampling

If a Moire pattern can be photographed using a film camera then there are
moire patterns which exist without a sampling device.

The Moire effect is the result of spatial undersampling an image, and the
Moire pattern is the aliasing. This is the reason that Canon and many
other camera manufacturers put an optical blurring filter in front of the
image sensor. The blurring filter is a spatial lowpass filter to prevent

Rumford's used an acoustic model of hot and cold radiation to give equal
existence to hot and cold radiation but the acoustic model has serious
limitations. I think a hole model would still treat hot radiation as
fundamental and cold radiation as only a secondary phenomena.
