Cold fusion comeback

'Cold fusion' rebirth? New evidence for existence of controversial energy source

Pretty clear evidence is given that a certain type of cold fusion device is producing neutrons. (If fusion is happening, there must be neutrons.)

Whether cold fusion ever proves useful for energy production is, however, another question.

UPDATE: the New Scientist version of the story goes into more detail, and provides an alternative explanation to fusion. (Not sure how credible it is, though.)
