How do you know that a faraday cage is part of the test? By definition, a Faraday cage is an enclosure made of a conductive material. One version of the hot cat is housed in a stainless steel tube, so it is a Faraday cage. There is another version which no one talks about any more, which is housed in silicon carbide. This ceramic version was the one Rossi described in his tribute to Focardi as a breakthrough, then it was never mentioned again.
