What is “cold fusion”?
The collection of phenomena that has come to be called “cold fusion” was discovered in the mid-1980s by professors Martin Fleischmann and Stanley Pons, who used their own money (about $100,000) to perform the electrochemical experiments that led to their announcement at a press conference on March 23, 1989 at the University of Utah. One of the most intense controversies in the history of science erupted almost immediately. The phenomena reported by chemists Fleischmann and Pons defied then current understandings of how nuclear reactions could occur—they were never thought to be able to happen under such mild, modest temperature conditions (with the exception of radioactive decay). In a small, vacuum-insulated glass cell they had electrically split heavy hydrogen (deuterium) from oxygen in the molecules of a heavy-water solution. The heavy hydrogen was compressed into a palladium metal electrode, after which the cold fusion effects emerged after days and weeks of careful measurement. Th
