I have not heard from Hydrobetatron https://translate.google.com/t…betatron.org/&prev=search in years. Surprised they are still around, and by the looks of their website they are still heavily involved. As I remember, they formed during the early Rossi years. I would suppose the founder Ugo Abundo is part of that European circle that still advocate for Rossi?
I tried a google search for their patent. The only link I got is back to Hydrobetatron. That means there is a high possibility of fake!
