cold fusion definition

The fusion of hydrogen atoms into helium at room temperature. In 1989 two scientists announced that they had produced cold fusion in their laboratory, an achievement that — if true — would have meant a virtually unlimited cheap energy supply for humanity. When other scientists were unable to reproduce their results, the scientific community concluded that the original experiment had been flawed.
