17 authors from 4 universities, and 2 industries alone is some form of independent verification. In addition, this is from their report:
"Reproducibility at different laboratories: Providing two divided sample powders of PNZ-type from
same-batch fabricated powder, independent parallel test runs were carried out at Kobe University and Tohoku University. Results of excess heat generation data from both laboratories were very reproducible for room-temperature and elevated-temperature conditions. Thus, the existence and reproducibility of new exothermic phenomenon by interaction of nano-metal composite samples and H(D)-gas have been confirmed."
P.S. This is my response to LINR's post moved to Clearance.
