The incredible paper about evidence for nuclear fusion in the deep Earth coming from some of my old papers spurred my curiosity about its background. The theory of geo-fusion seems to go back to a certain Steven Jones. He even published a Nature paper about it in 1989, in the heydays of the cold-fusion mania. But it has not been confirmed, as the search for magmatic tritium was not successful. The new paper by Jiang et al. seems to change that, but it does not convince even a tiny little bit.
It rather seems to me that this geo-fusion theory is of about the same quality as the theory of deep, abiogenic oil, of which I have already written. Alas, no deep oil or deep fusion will save us from what appears to be a serious energy crisis. Would be nice, but these theories are nonsense.
Interestingly, Steven Jones seems to like nonsensical theories. As his Wikipedia entry reveals, he is a strong proponent of the theory that the the World Trade Center was destroyed by controlled demolition during the September 11 attacks, rather than by the airplanes crashing into it. I don't have a high opinion of such conspiracy theories, as I mentioned before. It seems that Prof. Jones, as great a physicist as he may be, is due for a reality check.
Physicists (I am one!) tend to think that they are very intelligent. Sometimes, this leads them to venture into areas of which they do not know very much. I also do this, but I try to be careful. Others are sometimes overly self-confident. Such as the German physicists who tried to reject the greenhouse warming theory as contradicting basic physics. Somewhere along the way they lost track and started to produce deep nonsense. Too bad.
