Darden nearly a year [or more?] ago, he indicated that Rossi had a surprisingly good grasp of theoretical aspects of his work
Does Darden have any qualifications in the field of theoretical physics to make a judgement? Or was this just a salesman's flattering?
It is diffcult for me to say... now. Perhaps it is more of the latter. But, billionaires seem generally to somehow evade credential or qualification issues, as we have seen in US politics for a decade or more, and even more so recently.
But, Darden seems to have some genuine affinity for science and particularly environmental science, some quotes in italics below taken from this likely somewhat self serving source link:
"Beginning in 1984, he served for 16 years as the Chairman of Cherokee Sanford Group, the largest privately-held brick manufacturing company in the United States and previously the Southeast's largest soil remediation company."
"From 1977 to 1978, he worked as an environmental planner for the Korea Institute of Science and Technology in Seoul, which he was a Henry Luce Foundation Scholar."
"Mr. Darden serves on the Board of Governors of Research Triangle Institute in Research Triangle Park, NC."
"Mr. Darden earned an MRP in environmental planning from the University of North Carolina at Chapel Hill, a JD from Yale Law School and a BA from the University of North Carolina at Chapel Hill, where he was a Morehead Scholar. His 1976 undergraduate thesis analyzed the environmental impact of third world development and his 1981 Yale thesis addressed interstate acid rain air pollution."
No "theoretical physics" evident there. But maybe someone can show us his college course work and summer experiences. Certainly his experience and comments this earlier Fortune interview give us some of his claimed motives in the LENR field:
