Balls of steel. This topic is so poisoned after Fleischmann and Pons, nobody touches it willingly. Well, looks like almost nobody.
But seriously, it's like the bugbear of research nowadays. No matter whether it would be possible to do fusion in those conditions, or not, people avoid getting near this subject for fear of tainting their reputations and destroying their careers.
Personally, I'm not sure what to think about cold fusion. On one hand, making two D particles stick together is hard. On the other, the D soup within a Pd lattice is definitely a complex system and, probably, still has some surprises in store. Time will tell.
