Nuclear Matinee: Scientists announce nuclear fusion breakthrough
Researchers at the National Ignition Facility in California announced this week that they had achieved a major milestone on the path toward nuclear fusion as an energy source, as described in a paper published in the science journal Nature. For the first time, the energy produced in a nuclear fusion reaction in a confined hydrogen fuel exceeded the energy put in to start the reaction.
