It's a net negative with a factor of 400 or so. This breakthrough is not really a breakthrough, it's just marketed as such because NIF needs to justify their funding. Compressing pellets of fusion fuel using lasers has no chance of ever forming the basis of a nuclear reactor. It's scientifically interesting because a self-sustaining reaction (until the fuel was consumed that is) was achieved in a lab setting (as opposed to in a hydrogen bomb). There might be fusion plasma data in there that are of importance to more serious attempts at actually building fusion reactors.
