Introduction In the 1990s, Martin Fleischmann told Eugene Mallove and others that Paneth and Peters may have discovered the first indications of cold fusion in 1926. Paneth and Peters found indications palladium hydrides transmuted hydrogen into helium. They later retracted their results saying they were probably caused by helium permeating through glass. However, it remains possible that the helium was generated by cold fusion. . . .
