/snip/ Did he ever say "entire" factory or just heat a factory? :) Or was only his room? Seeing his old tests to McKubre, it should be something below <400W, if that was the state of the art back then. /snip/ In his patent application, he states:
[0060] A practical embodiment of the inventive apparatus, installed on Oct. 16, 2007, is at present perfectly operating 24 hours per day, and provides an amount of heat sufficient to heat the factory of the Company EON of via Carlo Ragazzi 18, at Bondeno (Province of Ferrara).
