me356 notes that he gets weird excess lighting in metal when he applies a stimulation signal that triggers excess heat

In our case with 'Signal' the very curious thing is that in GS5.2 we obviously do not have a LINAC in there, at least not in the traditional sense. It is just a Rossi patent fuel mix in a GlowStick. Also, we had no characteristic x-rays, meaning that our photons were not coming from one strike target, like Tungsen.

People formerly from the French Nuclear Authority immediately recognised our 'Signal' as equivalent to what you would see after a large beta burst.

ie a wide array of electron energies leading to a broad band of photons.

So Rossi fuel, leading to broad band of electron energies and photons and Nasa saying that transmutations / LENR occurs with energies of photons in the range produced.

Lastly, shoulders says that EM stimulation can allow CCs to release a range of electron energies dependent on that EM stimulation.

See page 21 here

This anomalous lighting could possibly be something like Cathode Luminescence which is due to electron beams. Hence me356 observing LENR excess heat when the anomalous glowing is happening (due to stimulated emission of electrons from the CC) and this would also explain reports from Rossi's Lugano reactor that the inside was glowing through the heater coils. Iron oxide, possibly on the surface, being a semi-conductor is a good candidate for being stimulated in this way.

Using different EM stimulation would lead to more heat, light or electricity.
