Defkalion claims to have technology that is “ahead of Rossi”. They claim that they will reveal, “announcements and initiated testing and certification by independent third parties.” in early December (15 days from November 20). They claim that they do not use Rossi’s methods. (http://nextbigfuture.com/2011/11/defkalion-claims-to-have-what-they-call.html)
But there’s more to this story. Check out this post on Defkalion’s blog. Maryyugo suggested that Defkalion has a relationship with Piantelli. The official line from Defkalion is that “we never answer/comment any post that is based on speculations.” However, a poster named Engineer says, “Indeed the html code for the image reads: /files/1/2011/11/18/Piantelli-engine%5B1%5D.jpg”
It is interesting that Defkalion would claim that they are “different from those of Rossi.” As Rossi claims that he has not revealed his catalyst to them, this is an interesting and brave claim. However, if they have a relationship with Piantelli, as Piantelli is clearly a previous inventor, this may give them the legal protection that they need.
The biggest thing that concerns me about Defkalion is the fear that they and Rossi get embroiled in a legal war that stops either technology from progressing.
