Thanks to Veblin for providing a link to a new article from the German Spektrum.de website titled “Cold Fusion: Hunter of the lost treasure.”
The original German article is here: https://www.spektrum.de/news/jaeger-des-verlorenen-schatzes/1564692
A Google English translation is here:
The author, Janosch Deeg, reviews the current field of cold fusion, and contrasts it with “Hot” fusion. He interviews Hartmut Zohm, professor of physics at the Ludwig-Maximilians-Universität München who is working on the hot side of fusion. Zohm was a doctoral student at the Max Planck Institute for Plasma Physics (IPP) time of the Pons and Fleischmann announcement, and neither he or his colleagues there could replicate the Pons-Fleischmann effect.
On the cold side of fusion, Deeg interviews Peter Hagelstein of MIT who is a champion of the LENR effect in the academic field, and is working to understand what might be going on the phenomenon. David Nagel, a professor of computer and electrical engineering at George Washington University tells Zeeg that there are results in LENR research that can’t be explained away. Swedish physicist Hanno Essén is also interviewed, he still seems convinced that Rossi has developed a working LENR process (Essén was one of the first academics to witness an E-Cat test).
From the article:
He [Essén] is pretty sure that the E-Cat is actually producing excess heat: “Based on the measurements I participated in and the reports of other independent scientists, I would say the evidence is pretty good that Rossi can generate unusual heat.” In his opinion, there are enough other physical effects that have not yet been explained. That’s why LENR is not unique to him. He describes Rossi as a “hard-working entrepreneur with numerous skills.” Essén criticizes, however, that for the inventor rather the economic than the scientific interests were in the foreground.
I think the article is a fair and neutral review of what is going on in LENR at the moment. On the experimental side of things, from numerous published articles and reports, there very interesting results that have been reported, which point to nuclear effects happening. But I don’t think things will change too much in terms of mainstream interest until there are useful products available in the marketplace.
