cold fusion

Cold fusion is a hypothetical method for achieving nuclear fusion at low temperatures, such as room temperature. This concept gained significant attention in 1989 when chemists Martin Fleischmann and Stanley Pons claimed to have produced fusion reactions at room temperature using electrolytic cells with heavy water and palladium rods.12

Despite their announcement, efforts to explain these results theoretically and to reproduce them worldwide were largely unsuccessful. Another disputed experiment in 2002 by Rusi Taleyarkhan and colleagues claimed to observe fusion reactions during acoustic cavitation experiments with deuterated acetone. However, most attempts to replicate these findings have also failed. These disputed experiments are distinct from the primary methods of harnessing fusion energy, which involve magnetic or inertial confinement of high-temperature plasma.2
