> This may turn out to be no improvement at all: just an indication that with enough power and energy, we get a slight energy payback. Or, this may be a method that can be greatly improved. We'll see.

Also two observations to be optimistic: it seems that the sensors were damaged because it exceeded its specifications (so we only know the lower bound of the produced power), and the NIF laser is old (which means it's inefficient). The only (skeptical) worry is that this announcement might lead to another fraud positive investigation event a la Ninov or Schön. I honestly hope not.
