This energy input, needed to\u00a0<a href=\"https:\/\/www.llnl.gov\/news\/national-ignition-facility-achieves-fusion-ignition\" target=\"_blank\" rel=\"noopener noreferrer\">power 192 lasers<\/a>, came from the electric power grid.<\/li>\n\n\n\n<li>Until recently, fusion has been seen primarily as a scientific experiment, not as an engineering challenge. This is rapidly changing and\u00a0<a href=\"https:\/\/www.nrc.gov\/docs\/ML2225\/ML22252A192.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">regulators are now investigating<\/a>\u00a0how deployment might unfold in the real world.<\/li>\n\n\n\n<li>What have we learned over the past 70 years since the onset of nuclear power?
