Third, what is that foil covered small box underneath the Ecat? Over half a year ago, Rossi was saying that the control unit (that could control up to 100 cats) was about the size of a box of cigarettes. In the demonstration, we see a foil covered box about that size under the Ecat. But the control unit is now supposed to be a heap of automotive looking parts off to the side. I don't get it!
Mark, on the basis also of Levi's paper it seems to me that the box under is simply a photovoltaic cell. Give a look to the report, in the introduction you will find phrases that talk about a "prototype A" (the long pyramidal box of figure 1). Prototype B seems a more compact version having shorter distance.
Measures were done on both obtaining comparable results.
"The prototype A under review (See figure 1) was looking like a cube of 150 mm side containing a light source and connected to a reflective pyramid, 600 mm high, which conveys light to a solar panel, measuring 500x330 mm, and some control sensors located at the base. A careful inspection of the apparatus verified that the entire structure was practically empty and weighed no more than 2kg. During operation a very intense blue light was emitted from the top and illuminated the solar panel and sensors at the bottom."
The play seems always the same to me, it contains a light source (like SKLed) inside a box that illuminates a PV cell in order to produce electric energy.
Being evident that the magician's claim about SKLed able to produce 10000 lumens is a pure scam, I strongly suspect the same about SKLep.
