I think I can believe in the possibility of Low Energy Nuclear Reactions, because on the surface it does seem possible to be able to exchange electrons at a low energy level.
However, it’s just a question of how useful this reaction is and whether it can be scaled up to industrial use.
Electrons exchange all the time...
You can force a neutron into an atomic nucleus, destabilizing the nucleus. I believe this is a common method for making radioisotopes. However, this process is a net consumer of energy, not an energy source.
Quite so. And even after useful devices are introduced, it commonly takes decades after the first models of products incorporating a major new technology hit the market before the technology becomes fully practical, affordable, and economically significant.
