It's a partly a problem of semantics, really. You can't really say it's a fusor runs at >45K because you're not in thermodynamic eq. (and therefore, there is no T).

Likewise a laser runs at "negative" T, but which is hotter than infinity T (pop inversion happens at T<0). There's no contradiction because T is again defined in eq., so we're just abusing terms.

So if we got net energy out of a fusor it would, for all practical purposes, be "cold" fusion. In fact, it doesn't have a T at all ;)
