Gulglielmi is confused. He wrote: "You are aware that several alleged technical mistakes have been pointed out, such as omitting control on DC current input (which has been acknowledged by Prof. Essén in a recent interview) and assuming that the output heat is released by a perfect black body . . ."
These are not mistakes. 1. It is not possible to do one test in which you check for every skeptical notion that people might come up, such as DC input. You have to do a series of tests with different power meters. 2. Assuming the device is a perfect black body is the most conservative assumption you can make. It reduces output to the lowest level it might be. Guglielmi's other assertions about the ethics of investigating anomalies are pure academic politics, and they are beneath contempt. - Jed
