> There is more than just a change of name involved with LCF: the statement "it still requires energetic deuterons" means the deuterons still have to be hot.

the original cold fusion experiments explanation was lattice confinement in heavy metal (i.e. large electron clouds) like Pt/Pd plus energetic deuterons. What was very unclear is where those deuterons got their energy. It was theorized something along the lines that high electrostatic charges in the metal cracks accelerate the deuterons, etc.

Unfortunately pseudo-scientificity got somehow attached to that research, and that for decades prevented any meaningful research into the source of those deuterons and how to efficiently increase their number and/or how to efficiently add another source. Only passage of time and the name change to LCF - marketing, yea! - has allowed to restart the research, though still without due credit to the original research.
