For the first time, researchers have created a fusion reaction that resulted in a net energy gain. The results, from the Lawrence Livermore National Laboratory in California, mark a significant step on the very long road toward generating clean energy from nuclear fusion.

“Last week, lo and behold, indeed, they shot a bunch of lasers at a pellet of fuel and more energy was released from that fusion ignition than the energy of the lasers going in,” White House Office of Science and Technology Policy Director Arati Prabhakar said at a press conference announcing the achievement in Washington, DC, today. “I just think this is such a tremendous example of what perseverance really can achieve.”
