Hi everyone!
The latest papers of Holmlid look interesting on the first view, and they seem to make some media attention.
But what exactly is "ultra dense deuterium", which seems to be the base of all other claims Holmlid made in his papers?
If you search the internet for it you will only find other papers at which Holmlid participated.
Did anyone independently report about "ultra dense" hydrogen gases?
This seems to be the very weak point on all of Holmlids reports
See this discussion at stackoverflow:

QuoteNo, I don't think there has been anything published in any reputable journal claiming to have reproduced Holmlid's supposed experimental discovery of ultradense deuterium. If there had been, it would have been big news.
He is active in the cold fusion community, so it would not be surprising if other cold-fusion kooks did similar experiments and presented them at true-believer conferences, etc. Holmlid is basically a one-man echo chamber who tirelessly pushes his crackpottery in online venues such as Wikipedia and physics.SE. Although he has managed to get his articles published in journals, a literature search showed that out of 2154 references to his papers, 1863 were self-citations.
Extraordinary claims require extraordinary evidence. Holmlid's claims, about both "Rydberg matter" and "ultradense deuterium," are extraordinary, and there is no evidence for them from any reputable experimentalist.
