Cold Fusion, not the programming language

My brother sent me a link to an article on real-life cold fusion, or, as the article calls it, a Low Energy Nuclear Reaction.

You can find the article here.

Apparently, the head of the Swedish Skeptics Society and the Associate Professor of the Swedish Royal Institute of Technology were present and given complete access to the experiment, even conducting parts of the experiment themselves.

The process combined nickel and hydrogen to create copper as a by-product, and produced 330 watts of power, 30 of which were used to power the controlling equipment.

This is quite an achievement, and will take our power generation technology a good step forward.

Though I do wonder just how large we might be able to make stuff like this. Would we be able to make powerplants capable of generating enough power to supply a city? How about a country?
Or even how small? Can we make them small enough to power single computers with ease?

Hmm, more questions than answers, but I'm happy to see something like this proven.
I'd like it even more if it were turned into something useful in everyday life.
