So I'm going to ask, as to cold fusion in general, "what has been promised" and what do promises have to do with science?

A new energy source has been promised.

By whom? And, I'll ask again, "What to promises [and speculations] have to do with science?"

Cold fusion is a natural phenomenon, it promises nothing unless a way can be found to make it happen reliably and with sufficient return on energy input to cover losses. Muon-catalyzed fusion, when discovered, was first thought to be a possible energy source. That remains as a possibility, but, the problem was, nobody knows how to make muons and keep them active long enough to recover the energy cost.

And... "convinced of what"?

Convinced that nuclear reactions in cold fusion experiments have produced measurable heat.

Thanks. Now, may I assume that you are not ignorant of the literature?

There are two questions here: the first is "measurable heat." We have a huge number of experiments, some being repeated series of identical experiments, showing "measurable heat." To be clear, this means, for most experiments, heat that is not expected from known prosaic processes, also called "anomalous heat."

Anomalous heat is heat of unknown origin, by definition. Is there such heat?

The second part of the question concerns the origin of the heat, whether the origin is nuclear or not. May we agree that anomalous heat, by itself, does not prove "nuclear."

But if we cannot agree that there is anomalous heat, surely we will be unable to agree on "nuclear." That's why the 2004 U.S. DoE review panel, 18 experts, was evenly divided on the question of excess heat, half the reviewers thinking that the evidence for it was "conclusive," but only one-third considered the evidence for nuclear origin to be "convincing or somewhat convincing."

Right? So, first question, is there anomalous heat?

Given that there are massive reports of it, widely published, from hundreds of research groups, 153 reports in mainstream journals as of 2009, there is only one sane way for you to deny it, as least as far as I can imagine.

That would be to claim that you know the origin of this heat, or at least that someone does. Otherwise it's still an anomaly. Right?

(The 2004 DoE panel, half, thought the evidence for anomalous heat to be "conclusive." If we imagine that the other half thought it was bogus, we end up with a paradox or conundrum. It's unlikely. In fact, the other half, probably, was mostly and merely "not convinced," which can be a lack of conviction from pure caution, some need to see more evidence, and for only for a few on the panel would there be a belief that the evidence was totally spurious. One reviewer seems to have thought that fraud was involved, as I recall, or certainly Bad Science. But this has become an isolated, fringe position. Sometimes, as well, people argue and apply logic from conclusions. I.e., if they believe that LENR is impossible, they then discount the evidence for LENR, more than they would if they were not attached to a conclusion. Human beings. Don't leave home without being one. This is backwards. There may be anomalous heat that is not of nuclear origin.)
