Are there theories that can explain cold fusion?
Cold fusion researchers have attempted to find theoretical models to explain the observed cold fusion effects: large thermal energy releases, low-level nuclear phenomena, and the absence of massive harmful radiation and other conventional nuclear effects. There is yet no single, generally accepted theory that explains all these phenomena. There is no doubt, however, that the phenomena exist and will eventually be explained. It is difficult to come up with a single theory that fits all the data. A potentially important point, however, is that considerable confusion about the potential role of electromagnetic effects and the application of conventional ideas involving quantum mechanics exists in the one reaction (involving deuterium fusion and the creation of helium-4) associated with conventional fusion that appears to be relevant to cold fusion. The underlying formalism (quantum electrodynamics and quantum field theory) associated with the theory that explains this reaction is actually
