Anyway, this group says it has achieved it but their report is very scant in details in order to make a proper assessment. I really hope they publish something more substantial, at this point what we need is many others to be able to replicate, no more stand alone successes that then fade due to lack of replication.
The problem is that this is potentially a very valuable technology so i can understand that people are hesitant to share details. Brillouin for example has burned through a couple of million already so they want to see a return on that investment. It would be great if there was more publicly funded research to reduce the need to keep investors happy. Sadly we all know the bad reputation LENR has in academia but maybe the new EU program could push this in a better direction. Hopefully they are willing to share and invite people to replicate, 1 result is worthless, the whole idea of science is to repeat and replicate results.
So the team replicated Prof. Mizuno results? They state that their reactor and possibly the catalyst are based on this research. The energy outputs are not super high but it is impressive that they were able to keep it stable for that long.
