I was very puzzled how a thin resistor wire in a red-hot cavity could cast a broad shadow on the outside surface.
> Figs. 1-2. Two images from the test performed on Nov. 20th 2012. Here, the > activation of the charge (distributed laterally in the reactor) is especially obvious. The darker lines in the photograph are actually the shadows of the resistor coils, which yield only a minimal part of the total thermal power. They don't --- see the Penon description of the first radiometry test (though that version had a hole in the middle) http://coldfusionnow.org/wp-content/uploads/2012/09/105322688-Penon4-1.pdf On page 5 you can see that there's a ceramic holder between two concentric cylinders : it looks like a long cog-wheel with the heater-resistor wires between the teeth. When this holder is inserted into the cylinder then the teeth of the "cogs" make good thermal contact with the outside, which shows up as hotter, brighter bands down the length of the cylinder. The gaps between the cogs do NOT make good contact, so they produce darker bands. Not shadows after all !!!!
