The document summarizes the history of cold fusion research, known as the Pons-Fleischmann effect. It describes how the initial 1989 announcement claiming cold fusion was met with skepticism by most scientists due to lack of evidence and reproducibility of results. While most mainstream science rejected the claims, a subculture formed to continue exploring cold fusion. Over time, some governments and militaries have provided limited funding for additional research on phenomena that cannot yet be explained by known science.
