The National Ignition Facility (NIF), a troubled laser fusion lab in California, has finally produced some results fusion scientists can get enthusiastic about. In a series of experiments last year, NIF researchers produced yields of energy 10 times greater than achieved before and demonstrated the phenomenon of self-heating that will be crucial if fusion is to reach its ultimate goal of "ignition"—a self-sustaining reaction that produces more energy than it consumes.
