Net Energy Gain of 0.3 kWh: Nuclear Fusion Achieves Historic First Profitability | Yunqi Science --- China's "Artificial Sun" EAST tokamak has set a new world record — sustaining a high-confinement plasma for 1,066 seconds. But there's an even more significant milestone you may have missed: for the first time in history, a nuclear fusion experiment has achieved net energy gain. On February 12, 2025, the U.S. Department of Energy's National Ignition Facility (NIF) announced that during its December 2024 experiment, the facility produced 1.3 megajoules of fusion energy while consuming 1 megajoule of input energy — a net gain of 0.3 megajoules, or roughly 0.08 kilowatt-hours (about 0.3 kWh when converted to the more commonly used "degree" unit in Chinese energy billing). This marks the first time humanity has extracted more energy from a fusion reaction than was put in — crossing the critical "Q=1" threshold where output exceeds input. ## The Long Road to "Burning Plasma" NIF's approach differs

Building Momentum, Advancing with Steadiness --- This appears to be a slogan or tagline (possibly for a company annual report, government work report, or institutional messaging). The four-character parallel structure is common in formal Chinese rhetoric. I've rendered it with rhythmic concision that preserves the paired conceptual contrast: "蓄能积势" (accumulating energy/momentum) and "行稳致远" (proceeding steadily to reach far — a classical idiom derived from *The Book of Changes*).
