For the first time, scientists have produced more energy in a fusion reaction than was used to ignite it. Researchers at the Lawrence Livermore National Laboratory in California say last week’s achievement is a clean energy breakthrough. The U.S. Department of Energy made the announcement Tuesday, calling it one of the most impressive scientific feats of the 21st century.
“Ignition allows us to replicate for the first time certain conditions that are found only in the stars and the sun,” Energy Secretary Jennifer Granholm said in a news conference in Washington. She went on to say this milestone moves the world one step closer to zero-carbon fusion energy “powering our society”.
