Breakthroughs in controlled nuclear fusion? The U.S. Department of Energy is about to make a major statement.

Beijing, December 12 (Xinhua) according to three people familiar with the preliminary results of a recent experiment, scientists at Lawrence Livermore National Laboratory (LLNL) in the United States have made a breakthrough in the pursuit of infinite zero-carbon energy, achieving the net energy gain of fusion reaction for the first time, that is, generating more energy than injected energy.

Scientists in the United States will announce a major discovery of nuclear fusion energy. Scientists who "understand the preliminary results of recent experiments" have discussed the results and analysis is under way. LLNL is scheduled to make a major announcement on Tuesday, December 13. The U.S. Department of Energy is expected to broadcast live around 7 a.m. Pacific time on Tuesday (20:00 Beijing time on Tuesday).

Since the 1950s, physicists have been trying to take advantage of the fusion reaction that energizes the sun, but no team has been able to generate more energy from the fusion reaction than it consumes. This is a milestone known as net energy gain or target gain and will help to demonstrate that the process can provide a reliable and rich alternative to fossil fuels and conventional nuclear energy.

LLNL has achieved a net energy gain in a fusion experiment in the past two weeks, according to people familiar with the matter. The lab used a method called inertial confinement fusion, in which the world's largest laser hits a tiny hydrogen plasma particle.
