Cold fusion
From Conservapedia
Cold fusion is the hypothetical effect resulting in excess heat that some scientists have claimed could be produced from nuclear fusion near room temperature. In 1989, electrochemists Martin Fleischmann and Stanley Pons of the University of Utah claimed to have produced such an effect by placing palladium electrodes in a glass of cold water, [1] and some speculated that this could become a source of cheap energy in the future. After Fleischmann and Pons made their claim, the effect was unable to be replicated by scientists, and the claim has been generally discredited since, although some scientists still try to create the effect.
