Cold Fusion
This is a branch of Fusion research attempting to produce fusion at low temperatures
Since the Fleischmann and Pons deuterium and palladium experiment in 1989 that could not be replicated to produce fusion, there has rightly been a very sceptical response to Cold fusion research, yet may papers have been written and research is still ongoing.
