In none of the articles linked there's numbers called, and without actual numbers on how much...
Quote:"...the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel..."
...we're unlikely to tell how much of a success this experiment was. If it's just an eV, then I'd hardly call that a success, as you'd need to exceed by several MeV at least.
H2-bombs and latest Fusion-bomb (Ivy) exceed the amount of energy put in too, doesn't mean it suits for commercial use.
