The US Department of Energy officially announced the milestone in fusion energy research. For the first time, researchers created a nuclear fusion reaction that produced more energy than they put into the process. The experiment, conducted at Lawrence Livermore National Laboratory in 吾舜 智 California, generated 3. 15 megajoules of energy, more than the 2. 05 megajoules put into creating it. Nuclear fusion works by forcing together two atoms-most often hydrogen-to make a heavier 如 one-like helium(氢). This explosive process releases massive amounts of energy, the Department of Energy explains. Fusion is the opposite of fission(裂变), the reaction that powers nuclear reactors used commercially today. Fusion occurs naturally in the heart of the Sun and the stars, providing these cosmic(宇宙的) 1 objects with fuel. Since the 195Os, scientists have been trying to reproduce it on Earth in order to make use of the so-called clean, cheap, and almost limitless electricity. According to the International E Atomic Energy Agency, fusion generates four times more energy per kilogram than the fission used to power nuclear plants, and nearly 4 million times more energy than burning oil or coal. What's more unlike fossil fuels, fusion doesn't release carbon dioxide-the greenhouse gas that's the main driver of s1 climate change-into the atmosphere. And unlike nuclear fission, fusion doesn't create long-lived 斑 radioactive waste. according to the Department of Energy. But so far, nuclear fusion hasn't solved our energy problems on a grand scale The recent announcement is a huge step forward in nuclear fusion energy, but applying the technology at commercial scale is likely still years away. Chanda Prescod Weinstein, a theoretical 班 physicist, pointed out that the process the Department of Energy uses requires tritium(氛)
