Harry E. PerrigoArchivado el 8 de octubre de 2007 en Wayback Machine., a vertical file at the Kansas City Public Library in Kansas City, Missouri, described as follows: "Photos, illustrations, and information on Harry Perrigo, a local inventor of a "free energy" device in the 1910s-1920s turning out to be a hoax. Energy source of "invention" supposedly "from thin air" or from "ether waves" but in actually from a hidden battery."

"Free Energy: APS Board Speaks Out on Perpetual Motion"Archivado el 22 de junio de 2012 en Wayback Machine., What's New, APS, 28 June 2002 "The Executive Board of the American Physical Society is concerned that in this period of unprecedented scientific advance, misguided or fraudulent claims of perpetual motion machines and other sources of unlimited free energy are proliferating. Such devices would directly violate the most fundamental laws of Nature, laws that have guided the scientific advances that are transforming our world."

Random Operators and Stochastic Equations (Walter de Gruyter GmbH & Co.) 9 (2): 161-206. Consultado el 24 de marzo de 2013. «Mostramos que la colección de artículos de la AIAS sobre la 'nueva electrodinámica', publicada recientemente en la revista Journal of New Energy, así como muchos otros trabajos firmados por este grupo (además de otros autores) que son reproducidos en otras publicaciones especializadas así como libros publicados por grandes casas editoriales, están llenas de malentendidos conceptuales. Estos errores básicos relativos a la teoría de campos magnéticos, así como gravísimas inconsistencias matemáticas, invalidan por completo casi todas las afirmaciones hechas por los autores aquí mencionados.»
