What is it with this field and all the "secret" scientist! First Rossi was always bringing in "experts" that were never revealed. Then it is reported that important and respected "visitors" who were impressed were working on the AE project and yet a year later not a peep from any of them.
Now this project has clandestine top notch secret scientist? Even Jed himself slightly criticized this approach a while back.
Yes, it would be wonderful if everyone involved would voluntarily step forward, identify themselves, and tell us exactly what they are doing, who is paying them, and what they have seen. Unfortunately, that is not usually how the world works. Most of these scientists who get involved do not want to be associated with LENR, and those that do not care about that, tend to be publicity shy.
So we have to be realistic in our expectations, and in this case thank our lucky stars Mizuno decided to do this the way he did. He *has* been as transparent to us as the language barrier, time zones, and his busy time constraints allow him. We should be thanking him, instead of nipping at his heels. Think about it; just 5 months ago he started seeing the big results in his lab, put his paper out only 2 months ago, directly answered some questions, and through Rothwell has answered many, many more...and we already have replications underway! Is that being "secret"?
IMO, complaints about secrecy, and how some researchers disseminate, or tease us with information, are legitimate. However, Mizuno is not one of them. Had he handled this the way others you mention have, this would have taken years to get to the bottom of. Instead we will know soon.
