Twenty-one years ago, two professors Pons & Fleishmann, announced that they had created some kind of nuclear reaction, but at low tempature. It caused a world-wide reaction. This is the promise of endless cheap power. The stuff that powers sci-fi spaceships and even planets.
Unfortunately, other labs had difficulty reproducing the results, there were all kinds of accusations, and the professors went on to different things (I've lost track). I guess these scientists can be much more vicious than I would have known; look at the climategate email string of scientists who were ready to off guys with an opposing viewpoint).
Anyway, it turns out that some labs and scientists around the world have continued to work on this, and it looks like something real was happening. Perhaps something at the quantum level, where the normal world vanishes and even Einstein was puzzled. On my permalinks is to lens-cagr where developments are reported. I periodically check in to see what is new, and I recommend that you do too.
