New work has answered criticisms by eliminating many of the suggested errors. Evidence for large and reproducible energy generation as well as various nuclear reactions, in addition to fusion, from a variety of environments and methods is accumulating. The field can no longer be dismissed by invoking obvious error or prosaic explanations.
Excess energy is generated without producing significant chemical products.
Evidence for local melting of palladium has been observed. Therefore, energy can be produced at rates and in amounts well above the result of any conceivable chemical reaction or plausible error. This experience indicates that commercial application is highly probable. Energy can be created by several methods, in at least nine different chemical environments. Therefore, the effect has a general nature and is not unique to palladium or to deuterium.
