Wisconsin state Sen. Chris Larson is excited by what he thinks could be looming in the world of fusion ignition.
“Are we close to harnessing the power of the sun for unlimited clean energy?” Larson posted on Twitter recently. “If a recent breakthrough by researchers in CA is any indication, the answer is ‘yes.’ Scientists were able to realize a net energy gain from a lab-created fusion reaction for the first time.”
In direct reaction to all the changes, the U.S. Department of Energy recently moved to announce that fusion energy researchers at the Lawrence Livermore National Laboratory in California have accomplished nuclear fusion, outlining the accomplishments as a huge scientific breakthrough brought on by years of research that could ultimately spark even more advancements in the areas of national defense and clean energy.
Nuclear fusion releases a large amount of energy by combining two light nuclei into a heavier one, a recent CNBC report said. For approximately the last eight decades, scientists have been working to replicate the sun’s fusion energy production on earth. The fusion experiment must generate more energy from the reaction than the laser energy used to drive it in order to accomplish ignition. This ultimately occurred in the experiment that took place on Dec. 5, with the reaction reportedly requiring two units of energy—or megajoules—and producing in the neighborhood of three megajoules.
Even with the new discovery and rising hope that fusion power plants will someday offer a road to clean and abundant energy, some seek to temper excitement by warning that such technological advancement likely remains years away.
“You have to have a robust system of drivers to enable that,” Kim Budil, director of the Lawrence Livermore Lab, said in the report. “So, you know, probably decades. Not six decades, I don’t think. Not five decades, which is what we used to say. I think it’s moving into the foreground and probably, with concerted effort and investment, a few decades of research on the underlying technologies could put us in a position to build a power plant.”
