Regarding "strange claims", last year at about the same period of the ECW blogpost linked above I was sent what looked like promotional material for potential investors on this company. Below is a supposedly independent report of Star Scientific's testing related to their catalytic oxidation apparatus (names redacted). If what they're doing is not just fancifully described but otherwise ordinary catalytic combustion, it might be more similar to what BLP/Mills are doing than Norront AS/Holmlid.
This all seems to come from a lack of a standard mainstream category for these phenomina inside the electromagnetic realm within the atomic well. Wouldn't be surprised if it was the same dense hydrogen cluster effects or attempts at achieving similar effects.
