Ummmm..... I'm gonna say not true. If they managed to produce a cold fusion reaction (lol, I love that - cold energy), it sure as hell wasn't in just some flask. Also, see this sentence:
It creates enormous amounts of energy, but it takes huge amounts of heat to happen at all.
Mostly the bolded part.
EDIT: the other articles were posted while I was typing. Reply as follows:
Lol, none of the articles are really all that consistent. The Fox one even gets the basic materials used wrong. The actual terminology of the experiment doesn't match up, mostly the Science Daily one where they call it an electrolytic cell (most definiately will NOT result in fusion). That name actually means to break down into electricity. I also have to wonder at the 'low-energy nuclear reaction' part. How useful is it if it doesn't produce that much energy?
